I was just driving to the store and all of a sudden without warning my van started to overheat and smoke the temp got to above 260 and it just stopped in the road. I had my children with me and had no idea what happened. My 17 year old son had to push me out of the road and I called my brother and he drove out to me and checked things out who is a mechanic and he said I blew a head gasket, he said these things happen but it should not have happened at 79,000 miles. I called around to see how much it would be to fix and so far no one will do it because it is alot of trouble.

Coolant leak at intake manifold gasket.

Car began leaking engine coolant from the back of the engine with only 60,000 miles on the odometer. Upon examination, it was found that the coolant leak was coming from the lower intake manifold gasket. This car has always run hot (between the half way mark and the red area of the gauge). The car finally overheated. The dealership said that there was no coolant in the engine, however the burp tank was nearly full, with no spillage. The dealership insisted that it overheated because of the leaking intake manifold gasket. We reluctantly agreed to replace the gasket to a tune of $1,376.00. The car still runs too hot in my opinion, but has not yet overheated.

Pontiac montana--found a coolant leak around the intake manifold--this is a known problem that gm does not seem to want to address (much info on the internet pertaining to very angry gm owners)--luckily (maybe) the problem will be fixed "forever".
