Drive Belt: Service and Repair

REMOVAL
Correct drive belt tension is required to ensure optimum performance of the belt driven engine accessories. There are different types of adjustment gauges for checking either a serpentine or a V-type belt. Refer to the instructions supplied with the gauge. Use the correct gauge when checking belt tension. Place gauge in the middle of the section of belt being tested (between two pulleys) to check tension. Do not allow the gauge (or gauge adapter) to contact anything but the belt. Belt tension is adjusted at the power steering pump bracket and idler pulley assembly.
1. Disconnect negative battery cable from battery.





2. Loosen idler pulley bolt (Fig. 5).
3. Loosen tension adjusting bolt (Fig. 5) and remove accessory drive belt.

BELT SCHEMATICS








The belt routing schematics are published from the latest information available at the time of publication. Vehicles not equipped with Power Steering have an idler pulley in place of the power steering pump pulley. If anything differs between these schematics and the Belt Routing Label, use the schematics on Belt Routing Label. This label is located in the engine compartment. Refer to (Fig. 6) or (Fig. 7) for correct belt routing, or refer to Belt Routing Label located in the vehicle engine compartment.

INSTALLATION
1. Check condition of all pulleys.








CAUTION: When installing the serpentine accessory drive belt, the belt MUST be routed correctly. If not, the engine may overheat due to the water pump rotating in the wrong direction. Refer to (Fig. 8) or (Fig. 9) for correct belt routing.

2. Install new belt. Install belt tension gauge C-4162 and tighten adjustment bolt (Fig. 5) until belt tension is within specification range.
3. Tighten idler pulley bolt and re-check belt tension. Adjust if necessary.
