Tools you'll likely need:
* Spark plug socket (usually 5/8" or 13/16", check your owner's manual)
* Ratchet and extension(s)
* Spark plug wire removal tool (optional, but recommended to avoid damaging the wires)
* Torque wrench (to tighten the new plugs to the correct specification – check your manual)
* Gloves
General Steps (remember to consult your Corvette's repair manual for specifics):
1. Disconnect the battery's negative terminal. This is crucial for safety.
2. Remove the air cleaner assembly. This gives you better access to the top of the engine.
3. Remove the relevant spark plug wires: Use a spark plug wire removal tool to gently pull the wires off the spark plugs. Number them or take a photo to ensure correct reinstallation. Cylinders 2 and 4 are on the passenger side of the engine.
4. Access to Cylinders 2 & 4: This is where it gets tricky and depends on what's in your way. You'll likely need to work around or partially remove some components. These could include:
* Fuel Injectors: They may be in the way; you may need to carefully move them aside or disconnect them (refer to your service manual; this is often a more advanced step).
* Exhaust Manifold: Parts of the exhaust system might obstruct access. You might need to carefully loosen some exhaust components (clamps and bolts) to create more space, but be aware of heat and burns. This is *generally not recommended* unless you're experienced.
* Other components: Vacuum lines, wires, and other engine accessories can impede access. Carefully move them out of the way.
5. Remove the spark plugs: Use the spark plug socket, ratchet, and extensions to carefully remove the spark plugs. Be careful not to drop anything into the engine.
6. Install new spark plugs: Install the new spark plugs to the correct torque specification (consult your owner's manual). Don't overtighten.
7. Reconnect everything: Reinstall the spark plug wires in the correct order, ensuring they are securely seated. Reassemble the air cleaner and other components you removed. Reconnect the battery.
Important Considerations:
* Repair Manual: A Haynes or Chilton repair manual for your 1988 Corvette is invaluable. It will have detailed diagrams and instructions specific to your vehicle.
* Safety: Work in a well-ventilated area. Be aware of hot engine components. Use caution when working near fuel injectors and the exhaust manifold.
* Experience: If you're not comfortable with automotive repair, it's best to have a qualified mechanic perform this task. Incorrect installation can lead to engine damage.
This is a general overview. Always consult your 1988 Corvette's service manual for the precise procedure and torque specifications. Improper procedures can cause damage to your engine.
