Use a straight blade or scraper blade and carefully work corner to corner downward but before you do this be sure to plug the holes into the engine to keep any debris from entering engine block and causing any damage. when you have the old gasket off use a cleaning solvent and a wrag and clean the entire area where the new gasket is gonna be as to prevent any potential leaks or air pockets.

I have a 95 gmc jimmy sle 4 wheel drive. The truck wont go into park i put a new neutral safety switch in and still same problem. Someone said asjust where and how do i adjust it???

Check all shift linkage under truck for loose bushings. Check also for bad transmission mount, engine mounts, bent linkage, etc. Also can be a problem inside transmission, often able to be fixed in the car by removing the trans lower pan to make repairs.

I had this happen to me the first time I replaced my intake manifold gaskets. It was hard to install the intake and gasket moved just enough and I had a coolant leak. Removed manifold and installed new gaskets and problem was solved. Good Luck.

1999 GMC Jimmy Running Hot w/ Engine coolant reservoir empty

I guess the burning question is , where is the coolant going.
Is this a 4.3 engine? How many miles does the vehicle have?
Has the intake gasket been changed?
I'm guessing a can of "Bars Leak" may cure your problem.
Let me know.
