Attention! An inertial hammer must be used to remove the chain guide locating pin. Sealant and new gaskets must be used when installing the drive chain top cover.
Removing
1. Remove the ground wire from the battery.
2. Drain the coolant from the cooling system.
3. Remove the cylinder head cover.
4. Disconnect the central high-voltage wire from the ignition distributor cover.
5. Unscrew the ground bar from the upper cover of the drive chain and release the electrical wires from the brackets on the cover. Remove the two bolts securing the coolant bracket and elbow to the upper timing chain cover and remove the elbow.
6. Remove the upper chain guide.
7. Remove the high voltage wire and unscrew the plastic shield from the base of the upper drive chain cover.
8. Remove the bolts securing the coolant supply pipe to the radiator fan and water pump. Disconnect the pipe from the water pump and move it to the side.
9. Disconnect the electrical connector from the camshaft position sensor and the camshaft adjuster relay that controls the intake valves.
10. Disconnect the vacuum tubes from the valve located on the front of the timing chain cover.
11. Remove the bolt securing the auxiliary drive belt tensioner post to the drive chain cover. Mark the location of the washers and gaskets for proper reinstallation.
12. Remove the plug from the upper timing chain cover located under the intake camshaft.
13. Screw an additional bolt into the timing pin of the drive chain guide.
14. Using an inertia hammer and an adapter, remove the chain guide pin by the head of the additional bolt.
15. Unscrew bolts of fastening of the top cover of a driving chain. In this case, the right bolt remains in the cover.
16. Remove the top drive chain cover.
17. Remove the gasket from the groove at the top of the lower drive chain cover.
Installation
Attention! When installing a new upper timing chain cover, check and, if necessary, adjust the position of the camshaft position sensor.
1. Clean the mating surfaces of the upper timing chain cover and cylinder head.
2. Apply a bead of sealant to the junction of the top of the lower timing chain cover with the cylinder head.
3. Install a new gasket into the groove at the top of the lower drive chain cover and lubricate the top surface of the gasket.
4. Apply a thin coat of sealant to the mating surfaces of the upper timing chain cover and cylinder head.
5. Install a new seal on the back of the timing chain cover.
6. Install the lower right bolt into the cover, then install the cover onto the cylinder head.
7. Install the remaining cover bolts and gradually and evenly tighten the cover bolts to the correct torque, starting with the bottom bolts.
8. Install the chain guide dowel pin.
9. Further installation is carried out in the reverse order of removal. Pour coolant into the cooling system.
