The low coolant light went on. The only way to fill the system is to open the reservoir cap. Unfortunately because the engine had a head gasket failure the cooling system would not depressurize, even when cold. It seems to me that there should be a pressure cap that when the engine overheats it allows the cooling system to depressurize. This closed system is very dangerous especially when someone who is used to filling the overflow tank when the coolant is low. Because the lack of an over flow tank anyone that opens the plastic reservoir could became burned.

Parked truck at outside stall and went indoors. After about 20 minutes I heard noises and went outside. Found the whole truck was engulfed in flames. By the time the fire department arrived 6 minutes later the fire spread to two additional vehicles. The heat melted and consumed everything except the frame. The fire investigator suspects the fire initiated due to electrical failure and generated from either the driver side dash board or left side of engine. The damage was too destructive to pinpoint exact cause.

In june, 2011, I began noticing my antifreeze levels were dropping slightly. There were no noticeable leaks of antifreeze anywhere. I attributed it to evaporation & added coolant. Over time the truck started using more & more antifreeze. A friend of mine noticed a puff of white smoke coming from the tailpipe. At the time I didn't really think anything of it. Last week while driving home from work after finishing up a "b" trick job (11pm), I noticed a knocking sound coming from the engine. It smoothed out after a few miles of driving it. The next day it happened again ( I work 26 miles from home) again it smoothed out & I was just grateful I got home safely that night. By this time I knew there were some serious issues & decided not to drive it again. I began researching the issue on line & found others that were experiencing identical symptoms. Turns out the problem lies with the cylinder heads in the engine manufactured for gm by castech. According to other people & by gms own admission, a faulty, weak material was used to build the cylinder heads. Over time the material wears away causing porous cracks & the antifreeze seeps into the oil system polluting it, causing significant damage to the engine. (by this time most extended warranties are up). The antifreeze mixes with the oil & is emitted out of the tailpipe as exhaust. This is why no traces of antifreeze were found & the reason for the white puff of smoke. Gm issued a bulletin #06-06-01-019b in june 2007 informing repair technicians on where to look for the damage. Through other peoples experiences, I am finding the engines were ruined in 90% of the cases & gm claims no responsibility. In my case I am driving a friend's vehicle waiting on word from my mechanic as to my options. These repairs are costly. Up to $5000!! This is not from normal wear & tear this is a manufacturing defect & I feel a recall should be issued.
