Changing the oil in a Nexia gearbox: how to change the oil in a Nexia gearbox

Checking the level and changing the oil in a manual transmission Daewoo Nexia N150

Tools:
Parts and consumables:

Notes:

Check and, if necessary, replenish the oil level in the gearbox every 10 thousand kilometers or 6 months. operation.

Check the oil level in the gearbox no earlier than two minutes after stopping the engine. Carry out the work on an inspection ditch or overpass.

Checking the gearbox oil level

1. Using a 13 mm spanner, unscrew the inspection hole plug located next to the inner joint of the right wheel drive in the gearbox housing and remove it.

2. Insert your finger into the hole and check the oil level.

Note:

The normal oil level is at the bottom edge of the hole.

3. If there is insufficient oil, remove the breather cap.

4. Unscrew the breather with a 17 mm wrench and remove it from the hole in the gearbox housing.

5. Clean the metal trap of the transmission inspection plug.

6. Use a syringe to add oil to the Nexia gearbox to the bottom edge of the inspection hole (see point 2). As soon as the oil starts to come out through the inspection hole

7. Tighten the breather and inspection hole plug.

Changing the oil in the Nexia gearbox

Note:

The Daewoo Nexia N150 gearbox is filled with oil for its entire service life. Only the instructions are silent about the length of the period, so presumably it is 100-150 thousand km, or 7-10 years of operation. In any case, even on a new car, it is recommended to replace the mineral water poured into the box with synthetic water.

Even during the operation of the car, it may be necessary to drain the oil and replace it, for example, when repairing a gearbox or when there is a significant oil leak from the gearbox, when it is not possible to add oil of the same brand that was poured into the gearbox. It is recommended to change the oil when the gearbox is warm.

1. Clean the bottom cover of the gearbox from dirt. Place a wide container with a capacity of at least 3.5 liters under the lid.

2. Using a 13 mm socket, unscrew the ten bolts securing the cover partly and drain the oil into a substitute container.

3. After draining the oil, completely unscrew the bolts and remove the cover. Clean it from deposits, wear products of gearbox parts and traces of the old gasket, and also clean the mating surface of the gearbox housing.

4. Then put the gear in neutral, chock the rear wheels, apply the parking brake and jack up the front left wheel to drain any remaining oil from the 5th gear housing.

Note:

You need to jack it high (to the height of the jack, maybe even more). Rotate the left front wheel backwards, and more old oil will spill out.

In this way, approximately 1.7 liters are drained, with a total volume of oil poured into the gearbox of 1.8 liters.

5. Lower the car.

6. Replace the transmission cover gasket with a new one.

7. Screw in the bolts and tighten them evenly to the specified torque.

8. Fill the transmission oil into the gearbox to the required level, as described in the first part of the article.

And a little about the author’s secrets

My life is not only connected with cars, but with repairs and maintenance. But I also have hobbies like all men. My hobby is fishing.

I started a personal blog in which I share my experience. I try a lot of things, different methods and methods to increase my catch. If interested, you can read it. Nothing extra, just my personal experience.

How to change the gearbox oil on a Daewoo Lanos or Daewoo Nexia?

You will find the answer to this question if you click the more details button.
Since the design of the gearbox
on the
Daewoo Lanos and Daewoo Nexia
does not provide for an oil change, but it needs to be replaced, when purchasing transmission oil (2 liters), you also need to buy a gasket for the bottom cover of the box (gearbox housing).
If for some reason there is no gasket, then you will have to get silicone sealant. The catalog number of the gearbox housing gasket for Daewoo Lanos, Daewoo Nexia, Chevrolet Lanos is 96179241.
Separately, a few words on the choice of gearbox oil for Daewoo Lanos and Daewoo Nexia cars.

.
The manufacturer recommends using transmission oil SAE 80W GL-4
; when operating a vehicle in climatic conditions where the ambient temperature remains below -30 for a long time, it is recommended to fill in
75W-90 GL-4
. That is, you can fill in both mineral water 80W90 GL-4 and synthetics or semi-synthetics 75W-90, 75W80, 80W85 GL-4. For example, I fill the gearbox of my Nexia with 80W GL-4 mineral water. I also tried synthetic 75W-90. Excellent oil, especially in winter, but in summer there is a small minus - noise in the box. Not strong, but there. That's why I switched to the oil recommended by the factory.

Now, step by step - Changing the gearbox oil on a Daewoo Lanos and Daewoo Nexia:

1. Unscrew the bottom cover of the gearbox

and carefully drain the oil from the box (photo 1) (if there is no new gasket available, then the covers must be removed as carefully as possible to avoid damaging the old gasket).

2. When the oil has completely drained, wipe the bottom of the box and the bottom cover with a dry cloth, removing traces of old oil and dirt.

3. After the bottom cover is installed (we use sealant when installing the old gasket), find the oil level control plug next to the internal drive (photo 2) and unscrew it. From the top of the box we look for the oil filler plug, carefully remove the plastic cap from it and unscrew it (photo 3).

4. Next, using an oil blower or syringe, pump transmission oil into the filling hole (photo 4) until oil begins to flow out of the control hole. We first tighten the control hole plug, and then the fill hole plug. Don’t forget, before doing this, clean the plug from dirt and put a protective cap on it (photo 5). It is not recommended to install and use the plug without a protective cap, since it simultaneously serves as a breather.

According to the manufacturer, an oil change in the Daewoo Nexia gearbox is not required during the entire period of operation of the car. However, he does not clarify how long this period is and how to check whether the lubricant has been used up or not. But the lack of lubrication in the gearbox can cause serious problems, as a result of which a complete repair of the gearbox will have to be carried out. And, as you know, it is expensive. To avoid this situation, it is recommended to change the lubricant in the Daewoo Nexia every 100 thousand kilometers. It is worth checking the oil level periodically.

It is almost impossible to determine what kind of oil the manufacturer poured into a car’s gearbox at the factory. But most often this “consumable” turns out to be mineral. And it thickens quite strongly at subzero temperatures. So if you are planning a replacement, it is better to buy semi-synthetic or synthetic lubricant.

Periodically, approximately every 15 thousand kilometers, it is necessary to check the level of consumables. As already mentioned, on the Daewoo Nexia the gearbox oil change is not provided for the entire time the car is used. But there are situations when there is a need for replacement. For example, when repairing a gearbox or when transferring a car to a new “consumables”. If a replacement is planned, then the old fluid should be drained while it is hot. This way it will be more fluid.

Changing the oil in the Daewoo Nexia gearbox yourself

Normal operation of the gearbox is impossible without lubricant. Thanks to oil, rubbing components and transmission elements do not wear out so quickly. This is why the fluid should be changed periodically. How to change the oil in the Daewoo Nexia gearbox and what will happen if you do not replace the lubricant on time, you can find out from this material.

Comments and Reviews

How often does an oil change need to be made?

To begin with, we suggest you sort out the question of when to change and fill new fluid into a manual transmission of a Daewoo Nexia 150 2011 or another year of manufacture. According to official data from the automobile manufacturer, the oil initially poured into the transmission at the factory must be used throughout the entire life of the vehicle. But the manufacturer also does not specify what the specific service life of the car should be. Therefore, the car owner will not be able to check whether this resource has expired or not.

Nexia gearbox

In order to prevent serious malfunctions in the operation of the Daewoo Nexia gearbox and avoid large financial costs, it is recommended to change the transmission oil after 100-150 thousand kilometers. Or every 7-10 years. If there are malfunctions in the operation of the unit or difficulties with switching speeds, the fluid can be changed earlier. The best option is to replace it every 100 thousand kilometers.

Useful tips

It is almost impossible to check what exactly is poured into the gearbox at the factory, but most often this oil turns out to be mineral oil, which thickens quite strongly in winter. When planning a replacement, it is recommended to purchase synthetic or semi-synthetic gearbox oil.

From time to time, at least once every 15 thousand km. mileage, you should check the lubricant level in the gearbox. The design of the Daewoo Nexia gearbox does not provide for lubricant replacement throughout its entire service life. However, sometimes the need for replacement still arises - in the case of a gearbox repair, when switching to a lubricant with a different viscosity, and in other similar situations. When planning a replacement, it is advisable to drain the old lubricant in a warm and fluid state, that is, within 10-15 minutes from the end of the trip.

Which oil is better to choose?

When changing the oil in a Daewoo Nexia n150 gearbox with 8 or 16 valves, you need to know what kind of lubricant should be poured into the system. The manufacturer does not regulate this replacement. Accordingly, you will not be able to find information about choosing a product in the service book. Practice shows that Daewoo Nexia gearboxes whose owners fill with synthetic or semi-synthetic lubricant last a long time. Initially, when a car is manufactured, mineral oil is used in the gearbox, so when buying a car it is also better to change it to “synthetic” or “semi-synthetic”.

Transmission "Daewoo"

The following transmissions were installed in Daewoo Nexia:

• five-speed manual;
• four-speed automatic.

The production of Nexia, equipped with a manual transmission, began in Uzbekistan. What kind of oil is used in this car? SAE 80W90, SAE 75W90 lubricant is used. Only hatchbacks that were produced in 1994-1997 are equipped with automation. Only Dextron 2 is filled into automatic transmissions.

It is worth noting that, in accordance with the recommendations of the Korean manufacturer, there is no need to change the Nexia gearbox oil. Its resource should be sufficient for the entire period of operation. This is approximately two hundred thousand kilometers. It is sometimes necessary to check its quantity and, if necessary, top up.

Changing the oil in the Nexia gearbox is intended only for regions where the temperature is very low (less than thirty degrees). This is due to the fact that in low temperature conditions mineral motor oil thickens. When making a car, mineral water is poured into it to save money. In view of this, it is recommended to change the mineral oil in the Nexia gearbox to synthetic/semi-synthetic before the car has driven one hundred thousand kilometers.

You need to know how to check how many liters of gear oil are in the unit. It is recommended to check it every 8-16 thousand kilometers. The oil in the gearbox must be poured with the same oil that is already filled.

How much should I fill?

It is equally important for owners of these car models to know how many liters are poured into the transmission. Service books for cars that require replacement of this consumable usually contain a table with fill parameters. In the case of an 8- or 16-valve Nexia, there is no such information in the service manual. However, before changing, you need to consider how much lubricant to pour into the gearbox.

As for volume, the transmission of the Daewoo Nexia should contain about 1.8 liters of oil.

History of Nexia

This Korean middle-class car was presented to the public in 1986. The development was carried out by German specialists (). The car was created on the basis of the Opel Kadett E, which was widespread at that time. "Nexia" began to be produced for residents of developing countries. Since 1995, cars have become available to citizens of the former Soviet Union. By the way, this car is known to Korean residents under the name “Daewoo Cielo”.

Ergonomics of Daewoo Nexia

The car stood out, first of all, for its low price. It cost no more than Russian front-wheel drive VAZs. The car was quite reliable, unpretentious in use, was ahead of Russian cars in terms of these characteristics and was not inferior to imported middle-class models. Replacing broken parts was easy due to their availability. All this explains the ubiquity of this machine.

However, Nexia gradually began to lose ground. The last car of this model was released four years ago. After this, the Korean manufacturer began producing the Daewoo Gentra.

Consequences of untimely replacement

8- and 16-valve Daewoo Nexia requires periodic replacement of transmission oil, since the additive package in the lubricant loses its properties over time. As a result, it becomes inoperable. Because of this, the liquid cannot provide the proper level of protection for rubbing surfaces. The loss of basic properties will lead to foaming of the working substance, which will ultimately cause scuffing of the main gear. As a result, the gears of the transmission differential will begin to hum, that is, the operation of the gearbox will be accompanied by a hum.

After 500-1000 km, the teeth on the gears will be destroyed. And this will lead to the transmission jamming. The driver will not be able to engage one or more gears. In Nexias with automatic transmissions, oil is also used to cool the unit. Failure to change the lubricant in a timely manner will result in kicks and jolts when shifting gears.

The best motor oil. does it exist?

• used oil loses its original composition, loses its lubricating properties and additives
• The viscosity level is significantly reduced, the oil foams and oil starvation occurs, as a result of which the rubbing parts of the manual transmission are subject to accelerated wear, and scuffing appears on the gearbox gears

To avoid the above problems, you must promptly:

• checking the fluid level. This must be done when the gearbox has cooled down every 8-10 thousand km. The fluid should be level with the bottom edge of the filler hole.
• checking the gearbox housing for the presence or absence of damage, oil leaks, etc. If leaks are detected, you must contact a diagnostic service
• analysis of oil by color, smell and content. The liquid should not have a cloudy color, there should be no sediment or metal particles in it. You should also pay attention to whether the oil is cloudy, dark, or clear in color.

Level control and topping up

Before changing the lubricant, you need to make sure that its level is normal. If the check shows a critical lack of fluid, you need to carefully inspect the unit for leaks. Visually assess the condition of the transmission - the gearbox should not have cracks or other signs of leaks. Otherwise, the problem must be solved.

Visually familiarize yourself with the process of replacing transmission fluid in a Daewoo Nexia car in the video (author - Alexandr Borziy).

To diagnose the oil level, do the following:

Tools

In order to replace the fluid in the gearbox of a Daewoo Nexia, you will need the following tools and accessories:

• jack;
• syringe;
• 13 mm socket head;
• 17 mm socket head;
• 19 mm wrench;
• oil directly;
• transmission pan gasket;
• container for draining used lubricant.

In order to choose the right gasket, it is first recommended to inspect the transmission pan from below. This is due to the fact that there are two types of pallets, having 10 or 11 holes - the number of holes must be checked before purchasing a gasket. In addition, you don’t have to buy a gasket, but remove the pan and cut it out yourself from paronite, or simply replace it with a sealant, which in practice copes well with the task.

How to change the lubricant yourself?

You can replace the working fluid with the help of specialists at a service station or yourself. Let's look at the process of changing it yourself.

Preparation

Before completing a task, you need to prepare. Buy two liters of lubricant and prepare the tools:

Before purchasing a gasket, be sure to inspect the pan on the transmission. On sale you can find two types of pallet gaskets, which are mounted with 10 or 11 bolts. Therefore, when buying a seal, make sure that it suits you. If it is not possible to purchase a gasket, you can make it yourself from paronite. As a last resort, if there is no seal, the perimeter of the pan must be coated with sealant.

Detailed instructions for changing the oil are given in the video (the material was filmed and published by the Expert R channel).

Stages of work

The replacement procedure must be performed in a garage with a pit or on an overpass:

Price issue

When performing work yourself, there is no need to spend money on service stations. You just need to buy lubricant. The cost of gear oil depends on the manufacturer. For example, one liter of universal “Mannol 80W-90” costs the buyer 212 rubles on average. Castrol 80W-90 lubricant costs about 350 rubles per liter canister. The cost of original Toyota oil of the same volume is about 730 rubles.

See photos of replacing transmission fluid yourself in our gallery.

Tool for changing gearbox oil

Replacement algorithm

The oil is changed when the engine is warm so that the waste is drained more completely. We install the car on the pit/overpass and begin work in this order:

Unscrew the plastic protection.

We turn out all the bolts of the pallet except the last two.

Drain the used oil.

Raise the front left wheel with a jack.

The control hole plug is unscrewed with the head at 13.

Instructions

Changing the oil in the gearbox is carried out on an overpass or pit. The replacement procedure includes the following steps.

Steps 1-3

4-7 steps

Step 8

Steps 9-11

1. If there is engine protection, remove it.
2. Using a 10 mm socket, loosen the transmission pan bolts.
3. We tighten the bolts in the front part of the pan and place a wide container under the drained oil.
4. After draining all the lubricant, completely remove the pan. In this case, even if the gasket does not break, it is recommended to replace it.
5. Usually only 1.5 liters of oil is drained, and 200-300 g continues to remain in the crankcase. To completely drain, you can raise the front left wheel to the maximum height possible with a standard jack.
6. Using a 13 mm socket, unscrew the oil level plug on the right side of the gearbox under the inner CV joint. Then we thoroughly rinse the plug itself from the inside, as well as the loose magnet located in its cavity.
7. After waiting until oil stops dripping from the gearbox, we install the pan in place, thoroughly cleaning its seat from old grease and gasket residues. The pan is installed with a new gasket or sealant, without tightening the control plug.
8. Next, you can fill in new gearbox oil. To do this, twist the breather in the upper part of the gearbox, next to the selector mechanism. Remove the plastic cap from the breather and unscrew it using a 19 mm wrench.
9. For convenience, insert a funnel into the breather hole and slowly add oil until it begins to flow from the plug hole, then tighten the control plug. As a result, about one and a half liters of lubricant is poured.
10. If the front left wheel was lifted to completely drain the fluid, then after closing the plug, add oil to the nominal volume. Otherwise, there is no need to perform additional filling.
11. All that remains is to screw the breather back to its original location.

At this point, replacing the fluid in the Daewoo Nexia gearbox can be considered complete. There is nothing complicated about this, all that remains is to check and make sure that the gears change easily enough, regardless of the time of year.

How to change the oil in a Daewoo Nexia gearbox yourself

If you are the owner of a Daewoo Nexia car, you may encounter a problem such as a lack of technical information regarding the frequency of oil changes in the Daewoo Nexia gearbox. Indeed, in the instructions, the manufacturer clearly indicates that the volume of transmission fluid will ensure correct operation of the gearbox throughout its entire operating life. Unfortunately, even if you try to re-read these lines several times, you still won’t find a word about when this operational period ends. We will try to help you in this matter by providing useful information to increase your knowledge regarding the operation of individual important components and mechanisms of your car.

Necessary clarifications

Depending on the country of production, Nexias were equipped with 2 types of gearboxes.

1. 5-speed manual.
2. 4-speed automatic.

Sedans produced in the Republic of Uzbekistan were equipped with manual transmissions. Daewoo Nexia manual transmissions must be filled with transmission lubricants that meet the following standards.

1. API GL4 SAE 80W90.
2. API GL4 SAE 75W90.

It should be noted that, according to the manufacturer’s idea, the lubricant resource poured into the Daewoo Nexia gearbox on the conveyor should be sufficient for the entire life of the vehicle. This corresponds to a mileage of 250,000 km, after which the oil needs to be changed. According to the instructions, every 15,000 km it is necessary to check the transmission level and top it up if necessary.

At the same time, according to the recommendations of the manufacturer, changing the oil in the Nexia gearbox is mandatory if the car has been operated for a long time at temperatures below -30 degrees Celsius. Therefore, in the northern regions of our country, changing the gearbox oil is usually carried out immediately after purchasing a car.

3- and 5-door hatchbacks produced in the Republic of Korea between 1994 and 1997 were equipped with automatic transmissions. Such units can only be filled with Dextron II gear oil. The Nexia automatic transmission has a reusable oil filter. When replacing the lubricant, it can be cleaned and put back.

Change of oil

Some motorists prefer to perform such manipulations almost immediately after purchasing a car, despite the extremely low mileage. They argue for their actions by the fact that oil could have been filled at the factory, accompanied by technical characteristics that do not suit the car owner. Indeed, the fact of such dissatisfaction and, to some extent, reinsurance is confirmed. At the factory, mineral oil is sometimes poured into the gearbox. This liquid is good in the summer. Unfortunately, in winter it becomes excessively thick, preventing the normal operation of the gearbox. It is for this reason that many people prefer to purchase synthetic or semi-synthetic oil.

Useful tips

If you have decided to replace the transmission fluid in the gearbox of your favorite car yourself, we recommend that you familiarize yourself with our useful tips. Initially, you need to check the oil level in the Daewoo Nexia gearbox. It doesn’t matter if you have absolutely no idea how to do this. We are ready to instruct you, eliminating the information gap. By the way, it is useful to carry out such a check after the car has once again covered 15 thousand kilometers. By checking how much oil is left in the Daewoo Nexia box, you can top up the missing amount in time and prevent gearbox failure.

Believe me, the gearbox can, of course, be repaired at service stations, however, such help will cost you too much.

So, to check the oil level in the Daewoo Nexia gearbox, you need to use a special dipstick, which you can easily find after lifting the hood.

This special dipstick has markings accompanied by the words “min” and “max”.

It is important that the trace of oil on the dipstick after removal from the hole is between these two marks. If you notice that it has dropped below the minimum mark, it means that there is an oil leak in the box. Be sure to add the missing amount and observe in the following days whether the loss continues or not by re-checking the oil level. If a lack of transmission fluid is again detected in the Daewoo Nexia gearbox, take steps to find the problem.

Replacement frequency

Understanding that driving on used material can cause serious damage to the gearbox, we recommend that you fill in new transmission fluid after one hundred thousand kilometers. Our recommendations are based entirely on statements made by professional service station technicians. Although there is a separate category of thrifty car owners who prefer to drain the used fluid after 60 thousand kilometers.

Well, you have the right to decide for yourself when it will be useful to replace the transmission fluid, but we recommend not delaying this process if the mileage has exceeded one hundred thousand. You should not save on purchasing consumables for your “iron horse”, since such savings can lead to even greater financial losses.

What oil to use

We have already drawn your attention to the fact that there are several options for transmission fluid, differing in their technical characteristics. In particular, when using mineral oil, the gearbox will function successfully, but only if there are no low temperatures. You won't be able to drive your car in winter if you use mineral oil; it will simply become too thick, with a high level of viscosity of the oil in the box. Accordingly, you will not be able to change speed normally.

Many motorists like 75W80 synthetic lubricant. We confirm that it is surprisingly good in cold winters, however, in the summer it can provoke the appearance of third-party noises and sounds, for this reason it is better for you to still opt for the Daewoo Nexia gearbox oil recommended by the manufacturer.

Tools for work

Don’t rush to take your car to a service station; you can handle such a task as changing the oil yourself. You just need to prepare for such manipulation first. In particular, it is important to collect all the necessary tools so that no difficulties arise during the execution process. Every motorist can assemble the tools, since the list consists of those devices that are always at hand. So, you need to prepare:

Don't rush to buy a gasket at random, as you may later be disappointed and upset about wasted money. The gasket may be accompanied by ten or eleven holes.

Take the time to look under the box and count the number of holes. If you follow this recommendation, you will be able to purchase the correct transmission gasket. By the way, if the process of purchasing a gasket is accompanied by difficulties, then you can make it yourself by cutting it out of paronite. You can also use a sealant without purchasing a gasket.

Checkpoint on the Daewoo Nexia - what will we use?

When purchasing oil, pay attention to the release date.

Despite the fact that the manufacturer declares the indefinite use of gear oil in the Daewoo Nexia gearbox, it needs to be changed.

Experts advise not to exceed the mileage before an oil change of 100-120 thousand km . Otherwise, there will be expensive repairs - synchronizers, seals, shafts will not last long on old oil.

Oil Standards

In the event of a forced oil change, the plant itself recommends using fluids of the SAE 80W , class not lower than GL-4 . In cases where the vehicle is operated in low temperature conditions, the recommended viscosity should correspond to the standard 75W-90 GL-4 .

The plant does not give clear recommendations regarding the composition of the oil, although initially it pours mainly mineral oils into the gearbox. The only advantage of mineral oils for gearboxes is the price.

Types and manufacturers

Otherwise, synthetic and semi-synthetic fluids work much better. This affects both the lubricating and washing properties of the oil and its durability. According to experts, the brand does not play a special role, although each driver has his own preferences. Castrol Syntrans 75w90 is perfect for Nexia .

Hochleistungs-Getriebeoil GL4+(GL-4/GL-5) 75W-90.

In addition to this oil, you can choose more inexpensive analogues that are no worse than the same:

• Castrol DriveLine 75W-90 Syntrax Universal;
• Castrol TAF-X 75W90;
• Castrol SMX-S;
• Hochleistungs-Getriebeoil GL4+(GL-4/GL-5) 75W-90;
• Hessol Hypoid Getriebeol SAE 80 W 90 GL-5.
