It seems that the this particular make and model has known problems with the cooling system. On a family trip to virginia the car started to overheat and I stopped the vehicle. When parked red fluid was visible under the car and upon testing was found out to be coolant leak. Car was towed to pa and mechanic reported loss and replacement of radiator/hoses and lower intake manifold (gasket) a labor intensive work costing about 1700 to fix all the issue with this over heating.

Every year, a week or two after turning on the heat in the van, the heater stops blowing warm air. While sitting at idle the temp gauge rises extremely high. Every year the dealer has fixed the problem. This year they are telling me that I need a new engine! After researching online, here and at respected sites such as edmonds.com it seems to me like these problems should have been addressed long before I even bought my van so many years ago!!!!

Driving the van I noticed the vehicle started to over heat. I turned it off and waited 1 hour for it to cool down. Started it up again after filling the radiator, with the engine running I made sure the coolant was at the correct level. Within 5 min the car overheated again and this time it died before I could turn it off. I have been told it would be best to replace the engine at 4100.00 for that. I searched the internet and found out there are many other van owners with the same problem. They used a rubber seal without steel so that it coolant leaks into the engine and mixes with the oil, and dries out the camshaft and then it breaks. In canada there is already a class action lawsuit for this reason. They (manufacture) know there is a problem but wont say that it is there fault. I am also looking to find someone to take the case as I currently have a lswn ornament due to I don't have the 4100 to replace the engine.

My van showed no sign of having anything wrong with it. Then on the way home from work it died at a light. It made awful noises and would not start. I towed it first to one repair shop and it was diagnosed with needing the engine replaced. Then I towed it to the dealer for a second opinion and was told the same thing. I was told at the repair shop that an engine with only 79,000 miles should not go out like this and it was due to the failure of gm parts. It still has not been repaired a year later.
