with an oil drain pan and a socket...make sure you have more oil to put back in...
4.3 quarts ,with new oil filter
The Grand Prix oil filter is located on the back side of the engine, near the oil pan. The oil filter is visible from beneath the engine.
4.5 quarts with filter change.
On a 2004 Pontiac Grand Prix the oil level sensor is located on the Oil Pan directly underneath the Air Condition Compressor.
if you dont know how the you should probobly have somone show you or take it to a shop
A 2004 Grand Prix GT will require approximately 5 quarts of oil. The type of oil required is 5 W 30.
All Grand Prix GTs and GTPs 1997-2003 will hold 4.5 quarts of oil in the engine oil sump. Hope this helps!
