Remove/Disconnect

The following camshaft timing procedure replaces the information in the published service manual. Use this new procedure to properly time the engine.

Clamps

J 38614 Camshaft Sprocket
Remover

Remove or Disconnect
1. Negative battery cable.
2. Air cleaner assembly.
3. Drain engine coolant.
4. Accelerator and cruise control cables from throttle-body.
5. Fuel rail cover.
6. Relieve fuel pressure.
7. Fuel lines from fuel rail and remove fuel mounting bracket.
8. Heater hose and bracket from lower intake manifold.
9. PCV valve and vacuum line from throttle body.
10. Electrical connector from EGR.
11. EGR valve and reposition.
12. Electrical connections from canister purge solenoid and MAP sensor.
13. Vacuum lines from upper intake manifold tee.
14. Wiring loom bracket for rear spark plug wires.
15. Power brake vacuum hose and remove upper intake manifold.
16. Coolant recovery tank.
17. Serpentine belt.
18. Serpentine belt tensioner.
19. Power steering lines from pump and reposition for pump removal. Refer to SECTION 3B.
20. Reposition PCM (1991-93 ONLY).
21. PCM mounting bracket (1991-93 ONLY).
22. PCM electrical connectors and reposition (1994-95 ONLY).
23. Spark plug wires from spark plugs.
24. Wiring harness cover at right strut tower.
25. Fuel line bracket.
26. Timing belt covers.
27. Breather hose from rear camshaft cover and crankcase vent from breather manifold.
28. Camshaft carrier covers.
29. Side plate bolts from actuator.
30. Rotate actuator assembly from the tensioner pulley socket and out of the mounting base.
31. Timing belt tensioner pulley.





32. Position actuator in vertical position in vise (rod tip down), clamp actuator body in vise lightly. (Figure 1)

IMPORTANT:
^ Allow oil to drain to boot end for at least 5 minutes prior to refilling.
^ The actuator assembly uses a tapered bushing between the actuator and mounting base. Do not lose or damage the bushing when removing the actuator assembly.

33. Straighten out a standard paper clip (0.032 inch diameter, no serrations) to a minimum straight length of 47 mm (1.85 inches). Form a double loop in the remaining end of the paper clip.
34. Rubber end plug from the rear of the actuator assembly. The assembly is filled with oil and removal of the plug may allow oil to escape. DO NOT REMOVE VENT LUG.
35. Push the paper clip through the center of the vent plug and into the pilot hole.
36. Insert a small screwdriver into the screw slot inside the actuator, behind the rubber end plug.
37. Retract actuator plunger by rotating screw in a clockwise direction, until it is fully retracted. Push on paper clip and slowly rotate screw counterclockwise until paper clip engages.
38. Timing belt.

IMPORTANT:
Remove timing marks from camshaft and intermediate shaft sprockets.

39. Rotate crankshaft so the # 1 cylinder is at TDC (top dead center). Mark the timing indicator with white paint (or equivalent) on the crankshaft balancer and front cover.
40. Position camshafts so the flat spots are "up" for installation of J 38613-A.
41. Install J 38613-A on both camshaft carriers.

^ 1991-93 Remove bolts, washers, and sprockets using J 38614.
^ 1994-95 Remove bolts, taper lock rings, and sprockets by lightly tapping on it with a soft faced hammer.
