We purchased a van in good working order in 04/2006. It was used previously by one owner since being purchased new. In november 2007- it began overheating and losing coolant. The diagnosis is now replacement of head gasket and possible intake manifold gasket. This is a very common problem with this particular engine. Gm has refused to help their consumers in any way if there is no warranty. As with all problems these could fail due to normal wear and tear, mileage, and or age. I do not believe this to be the case in numerous complaints including my own!

Dt*: the contact stated the low coolant light illuminated and the vehicle was not warming up properly. The dealership determined the antifreeze was leaking into the oil. The manifold gasket was replaced. When the problem returned the manifold gasket was replaced a second time. Two other members of contact's family had the same things go wrong with their vehicles. The dealer won't help the contact to defray the expenses because he used an independent mechanic that once worked at the dealership. There weren't too many dealerships in the contact's area. Also, the contact knew many people who had similar engine problems.

Began to see coolant pooling on the intake manifold assembly, took the vehicle in to find that the intake manifold gasket needed to be replaced. Should have been a warranty item. Did not damage engine, I was lucky and spotted the situation early.

The consumer stated the intake manifold gasket failed without warning. As a result the transmission fluid and oil began to mix together, which caused the engine to stall. Please provide additional information.

Coolant leaked from gasket into engine degrading oil and resulted in extensive damage and cost. The downgrading began with this event. Il pump eventually clogged resulting in low oil pressure & repaired again. *ak eventually, engine self destructed, while on freeway, loosing power steering and power brakes resulting in near accident while exiting freeway. Then had to rent a chrysler van to escape oncoming hurricane frances. This is more expense and aggrivation. All because of a faulty gasket leaking coolant into engine. This looks like neglegent design on gms part resulting in a catastrophic failure which could have resulted in death.

I have just found out that my olds silhouette has a coolant leak in the intake manifold withh only 50000 miles on the odometer. To my discuss I was informed that this is a very common and "predictable" failer. I hope that it has not caused any further damage to my engine. It would have been in the least a reasonable action on behalf of gm to give owners of their vehicles a heads up on this all to common defect.
