Removal
1. Disconnect the battery from ground.
2. Drain the oil and coolant.
3. Raise the front of the car.
4. Remove the lower shields.
5. Remove the radiator expansion tank.
6. Remove the spark plugs and all drive belts.
7. Having unscrewed the bolts (indicated by arrows), remove the air conditioning compressor and set it aside without disconnecting it from the line.
8. Remove the alternator, tensioner pulley and bracket (the lower bracket bolts are indicated by arrows).
9. Remove the cruise control actuator (if provided).
10. Disconnect the lower radiator hose and remove the coolant pump.
11. Set the piston of the 1st cylinder to TDC of the compression stroke.
12. Remove the cylinder head.
13. Remove the tray.
14. Secure the crankshaft pulley to remove the bolt.
15. Loosen the bolt and remove the crankshaft pulley.
16. Loosen the bolts (arrows) and nuts of the chain cover.
17. Carefully remove the lid.
18. Remove the chain and sprocket.
19. Remove the tensioner dampers and components.
Examination
1. Check the condition of the chain and dampers. Replace worn parts. If the dampers are heavily worn, remove and clean the pan and oil receiver.
2. Check the plunger operation. The plunger should move freely with the lock retracted.
3. Check the operation of the tensioner lock. The lock should securely hold the plunger.
4. Check the cleanliness of the oil injector jet.
Installation
1. Clean the front of the engine, chain and cover, install the nozzle. The nozzle should be facing the chain.
2. Place the chain on the camshaft sprocket, aligning the links with the reference marks on the drive and driven sprockets. Crimp the chain by tying it with strong tape.
3. Align the link with the distinctive mark (indicated by the arrow) with a groove for the crankshaft key (indicated by the arrow) and put it on the drive sprocket.
4. Apply a bead of sealant to the cover, make sure all gaskets are in place and install the cover (within no more than 5 minutes after application), by engaging the shaft of the leading rotor of the oil pump with the leading gear of the crankshaft.
5. Install the bolts and tighten to the specified torque (see subsection 3.1.1). The chain cover mounting bolts, which differ in size, are shown in Fig. Designation of chain cover bolts with different sizes. Remove the chain binding.
6. Install the remaining parts in the reverse order. Make sure the cover is installed correctly, fill the cooling system with liquid, add oil. Start the engine, make sure there are no leaks. Set the ignition timing and test the vehicle's performance.
