Hello All,

I recently had my 2007 H3 in for servicing because I noticed it was losing coolant from the reservoir tank. The tank would go bone dry in about 4-6 weeks of driving the vehicle. The dealer stated they saw no external leakage and I''ve noticed nothing in my home garage or parking spaces at work. They stated through their testing that the coolant isn''t going back into the transmission so they went ahead and replaced the head gasket. It was a hit or miss job they admitted! Well, the truck is still losing coolant and has 29K miles on the odometer. Would the Dex-Cool be evaporating somehow? Or could there possibly be a crack in the head or engine block? There should be external signs of leaking if that was the case, correct? I thought head problems only existed on the 06''s? I have yet to get a check engine light or overheating. On hot summer days the truck did run about 3/4 on the temperature gauge though. Any help would be greatly appreciated!



Thanks
