However, if you're comfortable working on cars, here's a general outline. Remember to consult a repair manual specific to your 1991 Corvette for detailed instructions and torque specifications. The following is a general guide and may not be entirely accurate for your specific model.
Tools You'll Likely Need:
* New serpentine belt: Get the correct size and type for your Corvette.
* Socket wrench set: Various sizes, including metric.
* Ratchet: To use with the sockets.
* Wrench set: Open-ended and/or combination wrenches.
* Pliers: For potentially removing belt tensioner bracket bolts (some might be difficult to reach with a socket).
* Jack and jack stands: For safe working conditions.
* Wheel chocks: Essential for safety.
* Gloves: Protect your hands.
* Shop rags or paper towels: For cleanup.
* Repair manual: Absolutely crucial for specific torque specs and procedures.
General Steps (Consult your repair manual for precise details):
1. Safety First: Park your Corvette on a level surface, engage the parking brake, and use wheel chocks. Raise the front of the car using a jack and secure it with jack stands.
2. Locate the Belt Tensioner: Identify the belt tensioner. This is a component that allows you to loosen the belt for removal and installation. Often, it's a pulley with a lever or a hydraulic mechanism.
3. Loosen the Tensioner: Use the appropriate wrench or socket to loosen the tensioner. This will create slack in the serpentine belt. This is the most critical step and the procedure varies depending on the tensioner type. Your repair manual will show you exactly how to do this. Don't completely remove the tensioner, just enough to release the belt.
4. Remove the Old Belt: Once the tension is released, carefully guide the serpentine belt off of the pulleys. Start by working it off the tensioner and then work your way around the pulleys.
5. Install the New Belt: Carefully route the new belt onto the pulleys, following the same path as the old belt. Make sure it sits correctly in all the grooves.
6. Tighten the Tensioner: Release the tensioner mechanism so that the belt is properly tensioned. Again, your repair manual is crucial for the correct procedure and torque specifications.
7. Double-Check: Visually inspect the belt routing to ensure it's correct. Make sure the belt is seated correctly in all the grooves.
8. Lower the Vehicle: Carefully lower your Corvette from the jack stands.
9. Test: Start the engine and listen for any squealing or unusual noises. Check visually for any signs of slippage.
Important Considerations:
* Belt Routing: The correct routing of the belt is crucial. Incorrect routing can lead to premature belt failure and damage to other components. Your repair manual will have a diagram.
* Tension: The belt needs to be properly tensioned. Too loose, and it will slip. Too tight, and it can put unnecessary stress on the pulleys and bearings.
* Specific Tools: You may need specialized tools to access some of the components, especially the tensioner.
* Year and Model Variations: There can be slight variations between different years and models of 1991 Corvettes. Always consult your specific repair manual.
Again, this is a general overview. Attempting this without a proper repair manual and mechanical experience is strongly discouraged. The consequences of a mistake can be significant. If you are not comfortable performing this repair yourself, take your Corvette to a qualified mechanic.
