Oldsmobile Spark Plug Parts Questions & Experts Answers
Q: How to replace spark plugs on Oldsmobile Cutlass?
A: To replace the spark plugs, assess their accessibility, especially if the car has air-conditioning or power steering, as special tools like extension or swivel tools may be necessary. Gather the required tools, including a plug wrench or spark plug socket, a feeler gauge for gap adjustment, and, for cars with HEI ignition, a spark plug wire removal tool. Before starting, obtain the correct spark plugs for your engine by referencing the Specifications section, the tune-up decal under the hood, or the owner's manual; prioritize the information from the tune-up decal if discrepancies exist. Ensure the engine cools down, inspect and adjust the gap on each new spark plug, and check for defects. Protect the car's exterior paint with fender covers. After allowing the engine to cool, remove a spark plug wire carefully, preferably with a removal tool, and use compressed air or a bicycle pump to clear debris from the spark plug area. Then, use a spark plug wrench or socket to remove the plug counterclockwise, and compare it for engine condition insight. Install a new plug by hand, ensuring it threads easily, and then firmly tighten it with a torque wrench. Inspect the spark plug wire before attaching it to the new plug, using a twisting motion, and route it away from the hot exhaust manifold. Repeat these steps for the remaining spark plugs, replacing them one at a time to prevent wire mix-up.
