As said before there is aluminum panel on the top of the block. Remove the bolts and the sensor on the right side. Do NOT lose your little rubber washers. VERY CAREFULLY lift the panel. You will have the four spark plug connectors on the panel. These are plastic and will break easily. It is best to replace these when you replace your spark plugs. Your spark plugs are in the engine block between the two valve covers. These you can get to with an extension and spark plug socket. Do not tighten spark plugs too tight or you can break them. The new plugs should gap at .60 Very carefully replace the aluminum panel. You will not feel any kind of click. Hand tighten the bolts into the panel. They should go in easily if you have the panel lined up correctly. Dont force the bolts or cross thread them.
For a 3.1 V6, they're easy to find but the back plugs are very hard to get at. Use a universal joint for your socket wrench and be prepared to do it by touch. I tried that once and it took me an hour. (Who designs these things anyway?) From then on, I take it to a pro.
A 6-cylinder has SIX and a 4-cylinder has FOUR spark plugs.... Am I missing something here?
Screwed into the head or heads. actually its not that easy to find the skylarks spark plugs. Just FIY one of them is under the alternator so have fun changin that one i know i didnt.
the spark plugs are located on the front of the engine under the hood
1 plug per cylinder so 6
I believe there is a slightly finned top on this motor (quad 4). remove the bolts on this and it should remove the finned plate, giving access to the spark plugs underneath.
I think it's .06 but if you get Bosch Platinum plugs, you won't have to worry about it.
It's a royal pain... The back plugs are the hardest to get at if you have a 6-cylinder engine. It's not impossible but you might have to rely on sense of feel. (Who designs these things anyway?)
Just follow the spark plug wires....
the oxygen sensor is located in/on the exhaust manifold.it looks like a spark plug with a wire coming out of the top
On a 1996 Buick Roadmaster, the spark plugs are located on the engine's cylinder heads. This vehicle typically has a V8 engine, so you will find the spark plugs on either side of the engine, beneath the ignition coils and covered by the engine's intake manifold. To access them, you'll need to remove the ignition coil packs and possibly the intake manifold, depending on the specific engine configuration.
Remove the spark plugs wire and remove the plugs wit a spaerk plug wrench or socket.
