I have a 2000 Chevy Blazer with 96K miles on it. I have had relatively few problems with it. Last week I had to get a new alternator and was told that my intake gasket was leaking coolant. They said it was not leaking coolant into the engine yet. If I have not had any problems with the engine overheating to this point, do you think replacing the intake gasket and coolant will fix the problem?
