I have a Pontiac Montana 2002, which I had Gm look for leak on at
56,000 kms and tested, it was clean, yet I had to add coolant before
the test. Now the van is at 65000 and again I have to add coolan. So,
GM Knows about the intake manifold leak. I have proof that the coolant
was down and added before the warranty expired and now after
expiration. Has anyone had a good experience with GM fixing this
problem, at their cost?
