Hi,

The only engine I am aware of that was used this model year was a 2.3L. Please confirm that is correct.

Here are the directions for replacement. This is for the 2.3L Note that the timing belt needs removed to replace the pump. I will provide those directions first.

NOTE:
- If you are installing the timing belt and the balancer belt, go to step 1.
- If you are installing only the balancer belt, go to step 7.

1. Remove and clean the balancer belt drive pulley.
2. Clean the timing belt pulleys, and the upper and lower timing cover.

Pic 12

3. Set the crankshaft to Top Dead Center (TDC). Align the dimple (A) on the tooth of the timing belt drive pulley with the pointer (B) on the oil pump.

Pic 13

4. Clean the camshaft pulley and set it to TDC.
-1 The "UP" mark (A) on the camshaft pulley should be at the top.
-2 Align the TDC grooves (B) on the pulley with the top edge of the head.

Pic 14

5. Install the timing belt in a counterclockwise sequence, starting with the drive pulley.
-1 Drive pulley (A).
-2 Tensioner pulley (B).
-3 Water pump pulley (C).
-4 Camshaft pulley (D).
6. Loosen and retighten the adjusting nut to tension the timing belt.
7. Clean any oil off both faces of the balancer belt drive pulley.
8. Check the lower cover rubber seal for cracks and other damage.

NOTE:
- If the rubber seal is coming off, apply liquid gasket to the lower cover and reinstall the rubber seal. Wipe off any liquid gasket that is pressed out.
- When replacing the rubber seal, clean the lower cover groove, cut the repair rubber seal to length, and put the rubber seal into the groove evenly.

9. Install the balancer belt drive pulley and the lower cover.
10. Temporarily install the crankshaft pulley and bolt.
11. Rotate the crankshaft pulley five or six turns counterclockwise to seat the timing belt on the pulleys.
