How do I locate and change the spark plugs on the 1998 Oldsmobile 88?

There will be 6 spark plugs. 3 at the front of the car between the engine and the radiator. 3 on the other side of the engine close to the firewall. You can follow the spark plug wires to locate each plug. The engine is transverse mounted, or sideways. It can be difficult to plugs on this type of engine because of clearance problems. I use a special spark plug socket that is extra long. Instead of using a ratchet wrench, I use a 7/8 inch ratcheting box end wrench on the socket. The socket has a rubber insert to hold on to the plugs after they have been removed from the engine. Be careful when removing the spark plug wire. They get stuck on the plugs, and pulling on the wire will damage it. If you don't have a tool designed for removing spark plug wires, twist the boot, or the big end of the plug wire that slips over the end of the spark plug. Once is is loosened up, you can pull it off the spark plug. Pull on the boot, never the wire. Only remove one wire at a time to avoid getting the wires crossed. To install the plugs, get a 6 inch length of rubber vacuum hose that will fit tightly on the end of the spark plug. Use this as a handle to install the spark plug into the engine. Once the spark plug is threaded in to the engine, pull the hose off the end of the plug and use the socket and ratcheting wrench to finish tightening.

Follow the grey plug wires to the spark plug just below the valve covers. Twist and pull wires off by the boot that slips over the plug. Remove plug
