Inspection Details for Drive belt:

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.

Removal & Installation Procedure for Chevy and Pontiac drive belt:----

Remove the air cleaner assembly.

Using Special Tool J-39914, or a suitable belt tensioner unloader, rotate the drive belt tensioner to release the tension on the drive belt.

Remove the drive belt from the right idler pulley.

Carefully release the unloader to relieve the drive belt tensioner spring tension.

Remove the unloader from the drive belt tensioner .

Provided the vehicle will not be raised or lifted to perform additional work. Utilizing a floor jack and a wood block, support the front of the engine unlock between the lift point of the floor jack and the bottom of the engine oil pan.

Raise the jack until the wood block comes into contact with the engine oil pan and is capable of supporting the weight of the engine.

If the vehicle is to be raised or lifted in order to perform additional work. Support the engine using the engine support fixture.

Remove the right engine mount.

Remove the drive belt from the remaining pulleys.

To install:

Install the drive belt to all the pulleys except the right idler pulley.

Install the right engine mount. Tighten the nuts to 81 ft. lbs. (110 Nm).

Remove the floor jack from under the engine oil pan or remove the engine support fixture.

Using tensioner tool and rotate the drive belt tensioner away from the drive belt.

Install the drive belt to the right idler pulley.

Accessory Drive Belts replace for Chevrolet and GM?

Chevy and GM car model drive belt replacing details.

The procedure here mentioned in this chapter is for
Chevrolet Avalanche, Express Van, and GM Savana car models.

In this chapter the details are provided for drive belt routing,testing,inspecting,replacing,adjusting and drive belt related help diagrams.

So the procedure is as follows:-----

Adjustment

These vehicles are equipped with a single serpentine belt and spring loaded tensioner. The proper belt adjustment is automatically maintained by the tensioner, therefore, no periodic adjustment is needed. If the pointer is past the scale on the tensioner replace the belt. If correct belt tension cannot be achieved make sure the correct belt is installed. If the correct tension is still not achieved and check for proper mounting off all accessory drives.

Inspection

Removal & Installation

Belt replacement is a relatively simple matter rotating the tensioner off the belt (to relieve tension) and holding the tensioner in this position as the belt is slipped from its pulley. The tensioner arm contains a machined receiver for a ³ / ₈ in. driver from a ratchet or breaker bar.

Fig. On this 4.3L engine, a large wrench (16mm) was used to pivot the belt tensioner and free the belt

Before you begin, visually confirm the belt routing to the engine compartment label (if present) or to the appropriate diagram in this section (if the label is not present). If you cannot make a match (perhaps it is not the original motor for this vehicle), scribble your own diagram before proceeding.

Disconnect the negative battery cable for safety.

Install the appropriate sized breaker bar, wrench, or socket to the tensioner arm or pulley, as applicable.

Rotate the tensioner to the left (counterclockwise) and slip the belt from the tensioner pulley.

Once the belt is free from the tensioner, CAREFULLY rotate the tensioner back into position. DO NOT allow the tensioner to suddenly snap into place or damage could occur to the assembly.

Slip the belt from the remaining pulleys (this can get difficult is there is little room between the radiator/fan assembly and the accessory pulleys. Work slowly and be patient.

Once the belt is free, remove it from the engine compartment.

To install:

Route the belt over all the pulleys except the water pump and/or the tensioner. Refer to the routing illustration that you identified as a match before beginning.

Rotate the tensioner pulley to the left (counterclockwise) and hold it while you finish slipping the belt into position. Slowly allow the tensioner into contact with the belt.

Check to see if the correct V-groove tracking is around each pulley.

WARNING
Improper V-groove tracking will cause the belt to fail in a short period of time.
