jack up your car enough where you can fit under it and you will see the bolts on the oil pan. there is like 10 or 12 i think. drain your oil first the loosen the bolts.you may have to get an engine puller to raise the engine some to get the pan off. make sure you have another gasket with the new pan or it will probably start leeking when you put it back on.
How do you take off a radiator for a 98 Buick Regal
Hey Andre==You don[t say which side but just get everything out of the way, remove the screws and take the valve cover off.
take the panel off the door, everything is inside
Take off positive battery cable.
V6 are a pain to get off. Try twisting back and forth, then pulling it off.
I had the same problem with my 98 buick regal gs and it turned out to be the ignition switch.
Only Ford products have a fuel shut-off switch. GM never used them. 1992 Buick Regal Owner

It is spring loaaded so take a wrench/ratchet and insert it into the square hole and pull against the spring and then you can get the belt off.
