I took the H2 back to the dealer today. Was out taking care of a few things and it started to get hot. Ambient air temp today is 107, by the time I drove the 20+ miles to the dealership the trucks temp was about 240. They have a new service manager now and a new master mech so I had the service manager pop the hood. Upon doing so his first comment was how hot it felt. They (the dealership) is going to take a look at it on Monday and then call me with options hopefully.
Taz, I don't need to block any air from getting to the radiator. The inner cooler for the Sc is doing a great job of that. It blocks about 2/3 of the radiator. I menationed that to the service manager today and said that for a noraml H2 installing a 160 t-stat may cause problems but I really think that it would help in my case. He seamed open to the idea but reminded me that simply changing the t-stat is not going to cool the engine. The point at which the fans come on would need to be adjusted as well. I said that should be possible with the flex-lite fans that are there now. He was also open to the idea of installing the fans from the GM 2500 series truck but didn't think it would be necessary.
ARH1956, thanks for the suggestion. I will ask them on Monday if they think it would help to change out the fans for a different model of Flex-lite.
As the ambient temps here cool I think my troubles will go away but it will only be a temp solution that will return again next summer. Hopefully with new people at the dealership someone will come up with a solution that will not cost me 1/2 the price of the truck.
thanks again guys for all the suggestions.
