Expected Procedure (Subject to Variation):
1. Disconnect the Battery: This is a crucial safety precaution to prevent accidental shorts.
2. Locate the Reservoir: The reservoir is likely located in the engine compartment, possibly near the firewall or under the hood, in a relatively accessible area. It might be plastic and relatively small. Look for the lines running to and from the windshield washer nozzles.
3. Drain the Reservoir: Before removing the tank, drain the washer fluid. This will prevent a mess. Use a small container and potentially some tubing to siphon out the fluid.
4. Disconnect Washer Lines: Carefully disconnect the rubber hoses leading to and from the reservoir. Use pliers if necessary, but be gentle to avoid damaging the lines. Note which hose goes where for reassembly. It might be helpful to take pictures.
5. Remove any retaining clips or fasteners: The reservoir is probably held in place by clips, screws, or bolts. Inspect the area carefully to locate these fasteners. You might need a screwdriver, socket wrench, or pliers.
6. Remove the Reservoir: Once all the hoses and fasteners are disconnected, gently remove the reservoir. It might be snug, but it shouldn't require excessive force.
Important Considerations:
* Corrosion: Given the age of the vehicle, fasteners might be corroded. Penetrating oil can help loosen them.
* Fragility: The reservoir and lines are likely to be brittle with age. Handle them with care to avoid breakage.
* Shop Manual: A shop manual specific to your 1981 Corvette is invaluable. It will provide diagrams, torque specifications, and crucial details about your specific model. This is the best resource for safe and successful removal.
If you're not comfortable performing this task yourself, it's best to take your Corvette to a qualified mechanic. Attempting this without proper knowledge could lead to damage to your vehicle.
