Timing Belt Installation Procedure For

Isuzu 1998-2000 3.2 & 3.5L DOHC V6 Engines

The AERA Technical Committee offers the following information on timing belt proce-

dure for Isuzu 1998-2000 3.2 & 3.5L DOHC V6 engines. Timing belt installation can be

accomplished by easily by following these six steps. NOTE: Previously published informa-

tion may not be accurate.

1. Make sure all timing marks are

indexed to their proper position.

Make sure the crankshaft is posi-

tioned (See Figure 1) so number

two cylinder (drivers’ side front)

is at TDC.

2. After looping the timing belt under

the crankshaft gear, start the belt

over the passenger’s side camshaft

sprocket, matching up the align-

ment mark on the belt (See Figure

3) . Use paper holding style pinch

clamps to secure the timing belt to

the camshaft sprocket (See Figure

2) .

3. Line up the driver’s side camshaft

sprocket to the timing mark (See

Figure 3) , by holding it in place and

install timing belt. Use paper

holding style pinch clamps to secure

the timing belt to the camshaft

sprocket (See Figure 2) .

4. Compress the timing belt tensioner

and insert pin to retain pusher.

Loosen tensioner pulley bolt. Apply

pressure on belt by rotating tensioner.

Tighten tensioner pulley bolt to

specifications. 14 ft/lbs (19 Nm) .

Remove pin from timing belt tensioner

pusher.

5. Remove pinch clamps from timing belt, if used. Install Crankshaft pulley, tighten center

bolt ‘finger tight.’ Rotate crankshaft two turns clockwise to remove timing belt slack.

Now tighten tensioner pulley bolt to specification.

6. Remove crankshaft pulley and install timing cover.

CAUTION: If reusing the old timing belt, ensure the direction of rotation marks

are pointing in the correct direction.
