Removal
1. Disconnect the cable from the negative battery terminal. Crank the engine to set cylinder No.1 to TDC.
2. Raise and secure the vehicle. Drain the refrigerant.
3. On 2.0L engines: Remove the exhaust manifold cover, EGR pipe and oxygen sensor.
The oxygen sensor (for 2.0L) must be removed before the next step. On 2.1L engines, the sensor can be left in place; using hammers on the exhaust system is not recommended.
5. Disconnect the exhaust pipe from the manifold; disconnect the mounting bracket from the engine block.
6. Disconnect the air filter mounting bracket from the unit.
7. Remove the two lowest intake manifold nuts.
8. Disconnect the spark plug wires from the spark plugs; remove the distributor, but do not disconnect any wiring from it.
9. Remove the valve cover.
10. Disconnect the air intake valve, air intake muffler and muffler hose from the air filter.
11. Remove the power steering pump, leaving the hoses attached. Move the pump out of the work area and secure it with a rigid wire.
12. Remove the exhaust manifold.
13. Remove the three upper mounting bolts on the intake manifold. Separate the manifold from the head and slide it back or away from the head.
14. Remove the thermostat housing as a whole without disconnecting the hoses.
15. Disconnect the heater hose from the head.
16. Remove the upper timing belt cover. Loosen, but do not remove, the timing belt adjusting bolt. Slide the belt off the camshaft pulley. Do not kink the belt or allow it to come into contact with engine fluids.
17. Remove the cylinder head mounting bolts. Remove the cylinder head.
To install:
18. Use a putty knife or similar blunt instrument to remove all traces of gaskets from the head and engine surface.
19. Once correctly positioned, place the new gasket onto the engine. Make sure the dowel pins and oil jet are positioned correctly.
20. Install the head. Lightly coat the bolt threads with clean engine oil. Hand tighten the bolts, making sure the two long bolts fit into the center holes.
21. Tighten the cylinder head bolts in two steps, following the pattern shown. On the first pass, tighten the bolts to approximately 30 Nm. On the second pass, tighten to a final tightening torque of 68 Nm.
22. Double check the engine position; it should be set at TDC for cylinder No.1. The pointer on the back of the cylinder block should align with the white mark on the flywheel. The "UP" marker on the camshaft pulley should be vertical and the alignment marks on the surface of the camshaft pulleys should align with the surface of the cylinder head.
23. Carefully place the drive belt on the pulleys.
24. Tighten the adjusting bolt.
25. Rotate the engine counterclockwise until the camshaft pulley has turned 3 teeth.
26. Loosen the adjusting bolt; this will tighten the belt. Re-tighten the adjusting bolt to 43 Nm.
27. Install the upper drive belt cover.
28. Install the thermostat housing.
29. Replace the gasket (always) and install the intake manifold. Start with the center bolt; make two or three complete passes, using a crisscross pattern when tightening the nuts. The final tightening torque is 22 Nm.
30. Using a new gasket, install the exhaust manifold. Start with the center bolt; make two or three complete passes, using a crisscross pattern when tightening the nuts. The final tightening torque is 32 Nm.
31. Install the power steering pump.
32. Install the air muffler, suction valve and hose.
33. Install the valve cover. Install the distributor, connect the spark plug wires. Attach the air filter mounting bracket to the engine block.
34. Connect the exhaust pipe to the manifold. Use new self-locking nuts and tighten them to 55 Nm. If the oxygen sensor is installed on the pipe, do not use hammers or pneumatic tools.
35. For 2.0L engines, install oxygen sensors, EGR pipe and heat shield.
36. Fill the cooling system.
37. Connect the cable to the negative battery terminal. Start the engine and let it idle. Check the work area for any sign of fluid leakage.
