1997 Chevrolet Tahoe Owner Comments

I own 2 GM vehicles. A 1997 Chevy Tahoe and a 2005 GMC Yukon. The Chevy Tahoe isand has(for several years) experiencing severe cooling system malfunctions and has now totally failed requiring expensive and extensive repairs. I have always followed the owner's guide and the manufacturer's recommendations as to using only "dex-cool" coolant and as a result it's use has caused the described failures to occur. The use of "dex-cool" has corroded and eroded all of the components in my vehicle's cooling system from the water pump, radiator, hoses, thermostat, heating core, etc. GM is denying that "dex-cool" played any role in these failures and therefore I must pay out of my own pocket for the repairs that GM knew would result from "dex-cools" use. My vehicle overheated and shut-off several times while on the highway and each time I was amid traffic traveling at "highway speeds". it was very dangerous! each time that it occurred I had the vehicle towed in for repairs and I was told to flush and refill with fresh coolant and that would solve the overheating/shut-off problem. The service was performed as per GM specifications and requirements each time. This most recent time is when the coolant "spilled" out from the water pump area and left me stranded once again. This time I was informed of the problems that now exist inside my cooling system and the expensive costs that I would incur for the repairs, replacements and "flushes" that would be needed in order to get my vehicle back on the road. All of the various mechanics and research into this matter have one common factor and that is the use of "dex-cool"!
