Removing and installing the timing chain Nissan Qashqai 2007 - 2013

Nissan Qashqai is equipped with petrol engines HR16DE (1.6), MR20DE (2.0) and diesel units M9R (2.0), K9K (1.5). On gasoline engines, regardless of the type of engine, the movement of the camshaft is driven by a chain drive. On diesel engines, the timing chain is only installed on the M9R (2.0).

According to the Qashqai technical data sheet, the procedure for replacing the timing chain is provided for Maintenance 6. See the photo report for how to cope with replacing the chain yourself.

How much does it cost and what chain to install?

On Qashqai with engine (1.6), production article number 130281KC0A is installed. The closest timing chains in terms of identity will be from the manufacturers Pullman 3120A80X10 and CGA 2CHA110RA.

Prices for these products vary from 1500 to 1900 rubles. For a Kashakai with a 2.0 engine, the chain with Nissan catalog number 13028CK80A will correspond. For an alternative replacement, timing chains ASParts ASP2253, price 1490 rubles, or Ruei RUEI2253, cost 1480 rubles, are also suitable.

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.

Timing chain Nissan Qashqai 1.6

On Qashqai cars with 1.6 liter engines, a chain is installed under article number 130281KC0A

. Manufacturer: VPM. Average price - 1400 rubles. Like the previous model, this substitute has a price on average 3 times lower than the original. There are no significant differences in the quality of this part from the original.

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.

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.

Run the engine and check for unusual noise or vibration.

Note: If the hydraulic pressure inside the timing chain tensioner drops after removal/installation, slack in the guide may cause a clunking noise when the engine is started and immediately thereafter. However, this does not indicate a malfunction. The knocking will stop after the hydraulic pressure rises.

Warm up the engine thoroughly and make sure there are no fuel or oil/fluid leaks, including engine coolant and engine oil.

Bleed the air from the pipes and hoses of the relevant systems, such as the cooling system.

After the engine has cooled, check the oil/fluid levels again, including engine coolant and engine oil. If necessary, top up and bring to the required level.
