So Fix it

Replacing the serpentine belt on your 1990 Silverado pickup will help prevent an accidental belt failure when you least expect it. The belt turns every accessory on the front of the engine, including the water pump and alternator. If the belt breaks, the truck will overheat and lose electrical power for the ignition system. Check the belt for damage every time you change the oil in your truck. Replace the belt at the first sign of a problem.

Instructions

1

Raise the hood of your truck and prop it open. Locate the negative cable on the battery. Remove the retaining bolt with a wrench. Lift the cable off the terminal and set it aside.

2

Locate the serpentine belt tensioner on the front of the engine. Place a socket and breaker bar on the tensioner center bolt. Rotate it counterclockwise to loosen the belt. Remove the belt. Rotate the tensioner back to the home position. Discard the old belt.

3

Install a new belt over the pulleys on the front of the engine. Leave it off the tensioner for now. Routing the belt correctly is important, so check the diagram on the radiator support under the hood to verify the belt path.

4

Rotate the tensioner counterclockwise with the breaker bar and socket. Install the belt over the tensioner pulley and rotate the tensioner clockwise to tighten the belt. Remove the socket and breaker bar from the engine compartment.

5

Reattach the negative cable to the negative battery terminal. Reattach the retaining bolt and tighten it with a wrench. Close the hood of the truck.

Removing a steering wheel from 1990 Chevrolet trucks requires a specialized pulling tool. You will need this puller because hammering on the shaft can cause damage. You might have to remove the steering wheel if you need to do repairs on the steering system or components in the dashboard or instrument cluster. Experienced home mechanics can do the job in a few simple steps.

Instructions

1

Pop the hood on the Chevy truck and disconnect the negative cable from the battery. Wait two to five minutes so residual power drains out of the truck. This is a safety precaution because you will be working with electrical components. Also, this will temporarily disable air bags, if the truck is equipped with them.

2

Pry up the horn pad with a screwdriver. You might want to use a screwdriver with the tip wrapped in tape so none of the screwdrivers edges cause any accidental damage.

3

Disconnect the horns grounding wire.

4

Remove the nut from the center of the steering wheel with a socket wrench.

5

Inspect the shaft of the steering wheel for any markings that denote position. If see any, mark the shaft yourself. It will help you reinstall the steering wheel correctly.

6

Fit the pulling tool at the center of the steering wheel. Turn it until the steering wheel becomes detached or can be pulled from from the shaft.
