Camshaft Replacement

Front

1. Do the battery removal procedure.
2. Drain the engine coolant.
3. Disconnect the radiator hoses (A).





4. Remove the exhaust gas recirculation (EGR) valve.
5. Remove the timing belt.
6. Remove the rocker arm assembly.
7. Remove the front camshaft pulley.
8. Remove the thrust cover (A), then remove the front camshaft (B).





9. Install the front camshaft in the reverse order of removal. Always use a new O-ring (C). Apply new engine oil to the journals and the cam lobes.
10. Apply new engine oil to the threads of the camshaft pulley mounting bolt, then install the front camshaft pulley.
11. Install the rocker arm assembly, then tighten the mounting bolts.
12. Install the timing belt.
13. Install the EGR valve, then connect the radiator hoses.
14. Adjust the valve clearance.
15. Do the battery installation procedure.
16. Fill the radiator with engine coolant and bleed the air out.
17. Do the crankshaft position (CKP) pattern clear/CKP pattern learn procedure.

Rear

1. Relieve the fuel pressure.
2. Do the battery terminal disconnection procedure.
3. Remove the under-hood fuse/relay box.
4. Drain the engine coolant.
5. Remove the quick-connect fitting cover (A), then disconnect the fuel hose (B).





6. Remove the heater hoses (C) and the bracket (D).
7. Remove the timing belt.
8. Remove the rocker arm assembly.
9. Remove the rear camshaft pulley.
10. Remove the thrust cover (A), then remove the rear camshaft (B).





11. Install the rear camshaft in the reverse order of removal. Always use a new O-ring (C). Apply new engine oil to the journals and cam lobes.

13. Install the rocker arm assembly, then tighten the mounting bolts.
14. Install the timing belt.
15. Install the heater hoses and the bracket.
16. Connect the fuel feed hose, then install the quick-connect fitting cover.
17. Adjust the valve clearance.
18. Install the under-hood fuse/relay box.
19. Do the battery terminal reconnection procedure.
20. Inspect for fuel leaks. Turn the ignition switch to ON (II) (do not operate the starter) so the fuel pump runs for about 2 seconds and pressurizes the fuel line. Repeat this operation three times, then check for fuel leakage at any point in the fuel line.
21. Fill the radiator with engine coolant, and bleed air from the cooling system with the heater valve open.
22. Do the crankshaft position (CKP) pattern clear/CKP pattern learn procedure.
