Pontiac Grand Am Problem Report
Pontiac Grand Am Intake Manifold Gasket May Leak Coolant or Engine Oil
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
I had the Low Coolant light come on. Took it into the dealer who said I need new Header Gaskets. I am assuming I need Lower Intake Manifold gaskets as well.
I've been reading that is a common problem with GM V6 engines as the DexCool coolant degrades the plastic gaskets.
This is apparently a known GM problem. There was a class action lawsuit that was settled in 2008 on this issue. However, GM should do a recall on this issue as it is huge. I will never buy another GM car or American car for that matter. - Visitor
noticed coolant on gound. kept adding coolant, sometimes twice a day. looked over engine compartment and saw puddle of coolent by manifold. clean area up, started car and found leak. Needs gaskets replaced. I called a repair facility was quoted between $1200.00 to $1800.00 to fix. Has Pontiac acknowledged this problem? - Visitor

My car started running rough and then wouldn't hold antifreeze. The mechanic thought it might be a head gasket issue, but it turned out to be the intake gasket, which is a cheaper fix, but not by much. I can't complain though, I've gotten a lot of miles out of my car. - Visitor
intake manifld gasket leaking antifreeze…also, ignition shutdown - Visitor
Over heats. Water pump brome. Got it replAced.. The over heated more than it did before. Looked online and says I have symptoms of cracked or blown head gasket.. Got bars leak head gasket sealer. It doesn't over heat anymore, but it does still leak coolant. I hate this star. But more money to fix than I paid for! - Visitor
I have had problem for quite a while, I will replace and see what comes of it, - Visitor
first I noticed my heater stopped working, then I had a problem with overheating it seems to be using a whole lot of antifreeze send my service engine soon light started flashing when I would hit 30 mph. Then after a good test drive I realized I had an oily substance on top of my engine. I'm guessing after reading all of the other comments this is exactly what is wrong with my car.. Very disappointed. - Visitor
