This operation requires removal of the timing belt. DO NOT attempt to remove the water pump unless you know how to remove the timing belt.
Removal
1. Disconnect the cable from the negative battery terminal.
2. Turn the crankshaft pulley so that the piston of cylinder No.1 takes the TDC position on the compression stroke. In this position, turning the crankshaft and camshaft is prohibited.
3. Drain the coolant from the radiator. Use a clean, dry container to drain the coolant, seal the container and dry any accidentally spilled coolant thoroughly.
4. Remove the engine support bolts and nuts, then remove the side mount and strut rubber gasket. Remove the cruise control actuator, if equipped. Move it out of the work area without disconnecting or twisting the cable.
5. Remove the splash guard from below the engine.
6. Loosen the power steering pump belt adjusting nut and remove the belt. Remove the adjusting pulley and the power steering pump. Slide the pump with the hoses.
7. Disconnect the wires from the generator, remove the generator through bolt, adjusting and mounting bolts, and remove the belt and generator.
8. On vehicles with air conditioning, remove the compressor mounting bolt. Remove the compressor and belt. Do not disconnect the hoses from the compressor, move it out of the work area and secure it with a rigid wire.
9. On fuel injected vehicles, remove the spark plug wires from the valve cover and the wiring harness protector from the cylinder head.
10. Remove the valve cover.
11. Remove the crankshaft bolt and crankshaft pulley.
This bolt is one of the tightest bolts in the car. When you loosen the bolt, the pulley is held in place by the old belt, but you should not support the pulley with the belt you are going to reinstall on the car. This will stretch or tear the belt.
12. Remove the camshaft drive belt covers.
13. Loosen, but do not remove, the adjusting bolt on the camshaft drive belt tensioner. Slide the adjuster off the belt and tighten the bolt.
14. Using chalk or a marker, mark an arrow on the timing belt. The arrow will indicate 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 pulley, being careful not to twist it and keeping it away from oil and coolant.
15. Remove the water pump mounting bolts, pump and O-ring.
To install:
16. Install the new O-ring and pump. Make sure the O-ring is not deformed or displaced. Tighten the mounting bolts to 12 Nm.
17. Double check the crankshaft position: cylinder number one should be at top dead center on the compression stroke. All of the following should be true: the pointer on the back of the cylinder block should line up with the white mark on the flywheel or drive plate (for an automatic transmission). The "UP" mark on each camshaft pulley should be up, and the corresponding marks on all camshaft pulleys should be aligned with the cylinder head surface.
On fuel injected engines, each camshaft can be pinned at TDC with a 5mm punch in the service holes located just behind each camshaft pulley. This greatly simplifies belt installation.
18. Install the camshaft drive belt so that it rotates in the same direction as before, remove the pins holding the camshafts if you installed them.
19. Loosen the adjuster and allow it to tighten the belt, then tighten the adjusting bolt.
20. Install the belt covers, except the top cover on single cam engines.
21. Install the crankshaft pulley and key. Coat the bolt threads with clean oil, but do not lubricate the bolt surface that contacts the washer. On fuel-injected engines, tighten the bolt to 150 Nm (110 lb-ft) and on carburettor engines, tighten to 115 Nm (85 lb-ft).
Tightening of this bolt is carried out with the wheels locked, the parking brake set and the gear engaged for a manual transmission or for an automatic transmission the selector lever set to the "PARK" position.
22. Turn the crankshaft counterclockwise until the camshaft pulley rotates by 3 sectors (teeth). Loosen the adjusting bolt, then tighten it to 43 Nm.
23. Install the valve cover and upper timing belt cover on carbureted engines. On a fuel-injected vehicle, install the spark plug wires and harness guard.
24. Install the air conditioning compressor and belt. Tighten the mounting bolts to 25 Nm. Adjust the belt tension.
25. Install the alternator and belt. Tighten the through bolt to 45 Nm.
26. Install the power steering pump, tighten the bolts to 27 Nm.
27. Install the side engine mount and cruise control actuator, if removed. Tighten the engine mounting bolts to 40 Nm and the nuts to 65 Nm.
28. Fill the cooling system with coolant.
29. Connect the cable to the negative battery terminal.
30. Run the engine at idle speed. Check the work area for signs of fluid leaks and the sound of belt beating or vibration of connections.
31. Turn off the engine and install the lower splash guard.
