CAUTION: This application may be an interference engine. DO NOT rotate camshaft or crankshaft when timing belt is removed, or engine damage may occur.



1. Disconnect negative battery cable. Remove air cleaner assembly. Remove upper fan shroud. Relieve tension on serpentine drive belt tensioner and remove serpentine drive belt.

2. Remove 4 cooling fan assembly mounting nuts and remove cooling fan assembly. Remove cooling fan drive pulley. Remove serpentine drive belt idler pulley assembly. Remove serpentine drive belt tensioner assembly.

3. Remove power steering pump with hoses attached, and set aside. Using Crankshaft Holder (J-8614-01) or equivalent, hold crankshaft from turning and remove crankshaft pulley bolt. Remove crankshaft pulley.

4. Disconnect harness connector from right side timing belt cover (if equipped). Remove timing belt covers in this order: right, left, then lower. Remove fan bracket (if equipped).

5. Rotate crankshaft to align timing marks. See Fig. 1 and Fig. 2. When timing marks are aligned, No. 2 piston will be at TDC.

6. If reusing timing belt, mark belt with arrow to indicate original rotation direction. Also place mating marks on timing belt and camshaft sprockets for reassembly reference. Remove timing belt tensioner, and set aside with push rod facing up. Remove timing belt.

CAUTION: To prevent air from entering timing belt tensioner, tensioner rod must always face up.


NOTE: This information outlines the proper steps to index the camshafts with the crankshaft. In the event that camshaft timing has been disrupted, due to timing belt breakage or camshafts/crankshaft being rotated without a timing belt, this is important prior to timing belt installation. Due to the gear-ration used by each camshaft pulley to drive the camshafts, engine timing cannot be indexed conventionally.

To compress tensioner pusher, place in soft-jawed vice. Slowly compress tensioner pusher pin until it lines up with the two small holes in tensioner pusher housing. Insert a straightened heavy duty paper clip through holes in housing. This will hold the pin in it's compressed position.

IMPORTANT: In the following procedure, the references to 9 or 12 O'clock positions are based on deck plane of the cylinder deck-to-cylinder head mating surface (as viewed from the front of the engine), and NOT relative to the shop floor.

Removal & Installation
Drain cooling system.
Remove timing belt.
Remove idler pulley.
Remove water pump bolts, water pump and gasket.

To install, reverse removal procedure.
Ensure gasket surfaces are clean.
Tighten water pump bolts in sequence to specification.
See Fig. 15.
Fill cooling system and check system for leaks.
