How to replace a mechanism chain
The timing belt on Nissan Qashqai with engine volumes of 1.5 and 2.0 liters, in addition, on other chain-type gasoline units, although the gas distribution system of the Nissan Qashqai 1.6 liter, which uses diesel for fuel, has a timing belt.
Replacing the mechanism chain of Nissan Qashqai 3.5.0 l, 1.3.2 l, 1.5 l should be carried out according to the regulations every 150–200 thousand km, and the belt on 1.6 l diesel engines should be changed after the same time period.
The chain mechanism is more reliable and durable compared to a belt, and you have to change it less often than is usually indicated in the manual. For the most part, it effectively fulfills its purpose even after 150 thousand km and can last up to 250–300 thousand km without complaints.
When working with the timing chain on a Nissan Qashqai 2L or other gasoline engines, done at home, you must follow the following sequence of actions:
- Remove the right front wheel.
Attention! It is important to carry out the full range of work with a cold engine!
- The first cylinder is set to the compression stroke: the crankshaft pulley rotates clockwise, here the TDC marks are aligned with the gear indicator.
- The belt located on the tensioner drive is removed.
- Next, the intake manifold and valve cover are removed.
- The crankshaft pulley and engine support are removed.
- The oil pan is removed.
- The next step is to remove the engine cover, for which purpose the bolts are loosened, the front oil seal is removed from the cover, which must be pryed off with a screwdriver.
- Then the tensioner, damper and the timing chain itself are removed.

Does the Qashqai have a chain or a timing belt?
The design of the timing drive on the Nissan Qashqai differs depending on the type of engine. Almost all Qashqais are equipped with a timing chain. The only exception is a car with a 1.5 liter K9K engine. This engine has a belt installed.
There are advantages and disadvantages in both cases. The most obvious advantage of a timing chain drive is its durability. The disadvantage is that it is noisier. But on the Nissan Qashqai, this problem is solved with the help of sound insulation. The timing belt is more elastic, cheaper and easier to replace, but has a shorter service life and the risk of rupture.
Since the most popular cars are those with a timing chain, we will consider what catalog numbers of the original spare part and its analogues it may have.
Symptoms
- engine error due to timing discrepancy
- poor starting on cold start
- knocking noises in the engine compartment when the internal combustion engine is running (from the timing drive side)
- spins for a long time
- poor engine thrust
- high fuel consumption
- a complete stop of the car while moving; when you try to start, the engine does not start, and the starter rotates more easily than usual
A timing chain with production part number 130281KC0A is installed on a Qashqai with a motor (1.6). The closest timing chains in terms of identity will be from the manufacturers Pullman 3120A80X10 and CGA 2CHA110RA.

List of internal combustion engine modifications
In the literal sense, the QR25DE motor has only two modifications:
Turbine for QR25DER Modification QR25DD
Factory boost made it possible to install a turbo engine on first-generation Infiniti JX35 and QX60 cars. The second version of the QR25DD was used in Nissan Primera cars. All attachments, with the exception of the TVS EATON compressor, remain unchanged.
However, the manufacturer changed the configuration of the QR25DE engine on-board system settings when installed on different minivans, sedans and SUVs, resulting in different characteristics:
Thus, by flashing the ECU, the user can do this at a service station using the appropriate equipment.
Timing chain Nissan Qashqai 2.0

RUEI2253
. Manufacturer: RUEI. Price – 1300 rub. Also a good analogue of the original spare part. A good combination in the price/quality category.
Tips and Cautions
It would be a good idea to replace the oil seal. Also, while the belt is removed, it is recommended to inspect the compressor and tensioner bearings and replace them if there are any unusual sounds or play. When assembling QR20DE parts, the bolts must be lubricated with grease so that they do not acidify and are easier to unscrew.
Timing chain tensioner QR20DE
Please note that the crankshaft cannot be rotated counterclockwise, since the timing chain may stretch in the opposite direction, push through the tensioner and slip (therefore, the marks will be knocked off).
Design of the Qashqai 2.0 liter engine.
The in-line 4-cylinder 16-valve gasoline engine has an aluminum cylinder block. The timing chain drive is equipped with a variable valve timing system with a phase shifter on the intake camshaft. There are no hydraulic compensators in the cylinder head. The valves must be adjusted manually by selecting pushers-washers of different thicknesses.
Nissan Qashqai 2.0 engine cylinder head
Nissan Qashqai block head
made of aluminum alloy. Two camshafts rotate in the bearing housing, which press their cams directly onto the valves through special pushers. The camshafts are not secured with separate covers, but with a common pastel. Spark plug wells have very thin walls; excessive force when tightening spark plugs leads to cracks in the cylinder head. The mechanism for changing the valve timing on the intake shaft is implemented using a hydraulic system. An increase in pressure causes an increase in the deviation of the camshaft from the nominal position relative to the valve axes. The oil pressure level is regulated by a solenoid valve controlled by the electronics of the Nissan Qashqai engine.
CHECKING AFTER INSTALLATION
CHECKING AFTER INSTALLATION
Leak check
• Before starting the engine, check the oil/fluid levels, including engine coolant and engine oil. If the level is below normal, add and bring to the required level. See chapter MAINTENANCE.
• Check for fuel leaks as follows:
-Turn the ignition key to the “ON” position (without starting the engine). After creating pressure in the fuel lines, check for fuel leaks at the joints.
— Start the engine. While increasing the engine speed, check again for fuel leaks at the joints of the fuel lines.
