I also had to have the actuator replaced on my GMC 2004 truck. It was blowing hot when the a/c was on and should have been cooling. It was not cheap either, it also had to be recalibrated in the computer system. I didn't expect that to happen to a new vehicle.

Gm has admitted it has faulty seals on the coolent system and has claimed dex cool is fine but the radiator caps are faulty as they corode. If the dex cool corodes the caps will it not follow it may corode other parts of the system? and if gm has admitted installing faulty seals why won't they at least recall this part and fix it instead of making the consumer fix it for them. I have been experiancing cooling system problems and wish the company would at least fix the problems they admit to. I do not want to go to the garage one day and find all the coolant on the floor.

My problems really began soon after the warranty was over @ 36,000 miles. At 42,240 I had a fuel injector go out, at 55,590 miles I had a water pump, seal, and core nipples go bad, along with the idle arm assembly, and the main engine belt replaced. Again only 2 weeks later @ 58,275 miles I still had a coolant leak, and it was then determined the intake manifold had developed a leak, and the thermostat and seal needed to be replaced. The again only 2 days later I again experienced yet another problem, this time the altenator went out! I complained to the dealer, and to general motors, who currently looking into the matter. The dealer did aggree it is fairly rare to have these problems so soon, and general motors aggrees. However that does'nt ease my mind, that their may be a design, or parts problem with these vehicles. I did talk with another owner of the same type truck a 1992, same style and engine, and informed me that he had exactly the same type of problems occur at aprox: the same milage time frame, and had several more pop up with the transmission as well.
