I have 1 1994 Seville and I need to check my coolant. I have the Northstar engine. My coolant tank has a pressurized radiator cap on it that does not seem want to budge. I have pushed down and turned like a standard cap does but it does not move..does not have much give up and down.

is there a special way this cap comes off?

Really push down while turning it counterclockwise. Like MC said, it can be somewhat difficult to get it off at times.

Yeah if you used the pallets and the stuff gunked up around the cap's rim and the cap was not removed in a while...you need fingers of steel.
