Cm. figures 100, 101 and 102.
1. Disconnect the cable from the negative battery terminal.
2. Rotate the engine to align the marks on the camshaft pulley and set cylinder No.1 to TDC. Once the engine is set to this position, it must not be rotated or moved.
3. Remove the engine support bolts and nuts, and then remove the side support rubber pad and bracket. Remove the cruise control actuator, if equipped; move the drive out of the work area without removing or twisting the drive cable.
4. Remove the splash guard from the bottom of the engine.
5. Loosen the adjusting nut for the power steering belt and remove the belt. Remove the adjusting pulley and the power steering pump. Move the pump out of the work area with the hoses attached.
6. Disconnect the electrical wiring from the generator. Remove the generator through bolt; remove the mounting and adjusting bolts and remove the generator and belt.
7. On vehicles with air conditioning, remove the compressor mounting bolts. Remove the compressor and belt; do not disconnect the lines from the compressor. Move the compressor out of the work area and secure it with a rigid wire.
8. On fuel injected vehicles, remove the spark plug wires from the valve cover and the wire protector from the cylinder head.
9. Remove the valve cover.
10. Remove the crankshaft bolt and remove the crankshaft pulley.
This bolt is one of the tightest on the entire car. The pulley should be held in place while the bolt is loosened. Wrap an old drive belt around the pulley to hold it steady - don't try this with the belt that's on the car; it will stretch or become damaged.
11. Remove the camshaft drive belt covers.
12. Loosen, but do not remove, the adjusting bolt on the camshaft drive belt tensioner. Move the tensioner away from the belt and retighten the bolt.
13. Use a piece of chalk or a marker to draw an arrow on the timing belt. The arrow can identify the direction of rotation or the outer edge of the belt. The belt should be reinstalled so that it runs in the same direction. Carefully remove the belt from the pulleys without bending it. Protect the belt from oil, coolant, etc.
14. This is an excellent time to check or replace the water pump. Even if you are only planning on replacing the timing belt as part of your maintenance program, plan to replace the pump at the same time.
To install:
15. If the water pump is to be replaced, install a new sealing ring and install the water pump. Make sure that the sealing ring is not deformed or moved from its position. Tighten the mounting bolts to 12 Nm.
16. Double check the engine position; it must be at TDC for cylinder number 1. All of the following conditions must be met: the pointer on the back of the cylinder block is aligned with the white mark on the flywheel, the UP mark on each camshaft pulley is up, and the alignment marks on each camshaft pulley are aligned with the edges of the cylinder head.
On fuel-injected engines, each camshaft can be held at TDC by using 5mm drifts inserted into the alignment holes just behind each camshaft pulley. This makes belt installation much easier.
17. Install the camshaft drive belt so that it rotates in the same direction as before. Remove the drifts holding the camshafts, if installed.
18. Loosen the adjuster and allow it to tighten the belt. Tighten the adjusting bolt.
19. Install the belt covers, except the top cover on SOHC engines.
20. Install the crankshaft pulley and key. Coat the bolt threads with a light oil, but do not lubricate the end of the bolt that contacts the washer. On fuel-injected engines, tighten the bolt to 150 Nm; on carburetor engines, tighten the bolt to 115 Nm.
This tightening is best done with the wheels locked (using the parking brake) and the gearbox in gear for a manual transmission or with the selector lever in the "PARK" position for an automatic transmission.
21. Rotate the engine counterclockwise until the camshaft pulley has turned 3 teeth. Loosen the adjusting bolt, then tighten it again to 43 Nm.
22. Install the valve cover and upper timing belt cover on carbureted vehicles. On fuel injected vehicles, connect the spark plug wires and harness protectors.
23. Install the air conditioning compressor and belt. Tighten the bolts to 25 Nm. Adjust the belt tension.
24. Install the alternator and belt. Tighten the through bolt to 45 Nm.
25. Install the power steering pump and belt, tightening the bolts to 27 Nm.
26. Install the side engine mount and cruise control drive if removed. Tighten the engine mount bolts to 40 Nm and the nuts to 65 Nm.
27. Connect the wire to the negative battery terminal.
28. Run the engine at idle speed. Carefully check the work area for any sign of fluid leakage or the sound of belt beating or vibration of the connections.
29. Turn off the engine. Install the splash guard.
