Pontiac Trans Sport overheating problems

Filed Nov 7, 2008 · Engine · MI

In nov. Of 2007 I was having a problem with my van overheating and was losing engine coolant but could not see where it was going. I later found out that I had a faulty intake manifold gasket, which cost me over 800.00 to repair. Not long after the gasket was repaired the van started overheating again and I discovered that the water pump was blown, that was another 174.00 to repair. Now I am still having the same problem with the van overheating and coolant leaking and I was just informed that it is a head gasket which is going to cost me over 1700.00 to fix. This is ridiculous, I know 3 other people who have the same make and model van as I do with the same engine and they are all also having the same problems with their vans. It seems to me that this is too much of a coincidence and that their should have been a recall in place to rectify the problems with these faulty parts. These are extremely expensive repairs and I personally do not have an extra $1700.00 just laying around, so now I am faced with the choice of junking my van and trying to get a new one which I cannot afford or fixing it which I also cannot afford.

With respect to my 1999 pontiac transport van, october of 2003 the engine started overheating and we discovered that the coolant was low. We added coolant and some type of seal into the coolant because we were told by several gm mechanics that it was probably the head gasket and this seal would help to get us by until we could have it fixed. I called the company where I purchased the van (2nd hand) and the van was no longer under warranty (over by 4,000 miles at the time). I did purchase the extended warranty. We priced around for the cost to have the head gasket repaired/replaced and found that we would have to spend between $800 and $1,000 to get it fixed. Our van is now sitting in a garage being torn apart and the head gasket was the problem. Prior to october 2003 we had the coils changed and the #5 plug was showing a malfunctioning problem which was showing up on the computer. When we brought it to the garage they replaced the plugs. We were told by the mechanic who is currently working on the gasket that the coolant was leaking out on the #5 gasket and this was the problem previously which was not picked up on by the past mechanic. This has been an ongoing problem for us since about june of 2003.
