How to Replace the Timing Belt on a 2001 Isuzu Rodeo

The Isuzu Rodeo is a pickup truck manufactured from 1988 to 2002. A common engine for the 2001 model is a four-cylinder, 2.2-liter engine with a double overhead camshaft (See Reference 1) (See Reference 2) . This engine requires a timing belt to keep the crankshaft and camshaft synchronized. The most important part of replacing the timing belt is ensuring that you keep the crankshaft and camshaft in the correct position during the procedure.

Instructions

Removal

1

Disconnect the negative battery cable with a socket wrench to ensure you dont inadvertently start the engine.

2

Turn the drive belt adjuster clockwise with a box-end wrench to relieve the tension on the the drive belt. Remove the drive belt.

3

Detach the electrical connectors from the chassis wiring harness in the left rear quadrant of the engine compartment.

4

Disconnect the bolts that attach the crankshaft pulley to the crankshaft with a socket wrench, and remove the pulley.

5

Remove the retaining nut that attaches the engine harness cover to the front of the engine, and detach the cover.

6

Remove the cover for the timing belt with a socket wrench. Rotate the crankshaft clockwise to align the timing marks on the crankshaft with the timing marks on the crankshaft housing.

7

Disconnect the adjusting bolt for the timing belt tensioner and remove the tensioner from the engine. Detach the timing belt from the crankshaft and camshaft.

Installation

8

Connect the timing belt tensioner and tighten the adjusting bolt by hand. Turn the crankshaft clockwise to align its timing marks if necessary.

9

Place a "J-43037" tool between the intake sprocket and exhaust sprocket of the camshaft to hold the camshaft in place while you install the timing belt.

10

Install the new timing belt while keeping the tension side of the belt taut. Turn the adjusting lever on the timing belt tensioner clockwise until the pointer on the tensioner moves to the center of the "V" notch on the tensioner housing.

11

Tighten the adjuster bolt for the timing belt tensioner to 18 ft. lbs. with a torque wrench.

12

Replace the front cover for the timing belt and tighten its mounting bolts to 53 in. lbs. with a torque wrench. Attach the electrical connectors for the engine harness. Connect the crankshaft pulley and torque its mounting bolts to 14 ft. lbs.
