ENGINE AND ENGINE COOLING
06/15/201195000
 In june, 2011, i began noticing my antifreeze levels were dropping slightly.there were no noticable 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.

 Truck has 14000 miles, it has constant over heating problems while towing my 8k travel trailer. i have talked with the chevrolet dealer about it, they told me that they were aware of the problem but at this time have no fix. i call stupid because i heard online that the 06 models have revised cooling systems and a larger turbo charger. my belief is the fix is to much $$ and they will only take care of the few people that tow and have issues. i have notice a lot of information on the net about 04.5 and 05 lly duramax truck that tow over 10000 have this issue but my travel trailer fully loaded only weighs under 9k. the major down side is the trucks inability to maintain the speed limit due to the overheating water temperature and the power loss formed a cooling fan that runs hyperspeeds no stop when towing. my towing has been done at low outside temperatures ranging for 75 to 85 degrees outside. this truck is not performing as advertised or supposed to be designed for. *nm

 Truck has 11000 miles, been in the shop 5 times for over heating while towing. gm technician line has a case # on file, and told the technician who relayed the information to myself that they were aware of the problem but at this time have no fix. i call bs because the 06 models have revised cooling systems and a larger turbo charger. my belief is the fix is to much $$ and they will only take care of the few people that tow and have issues. i have notice a lot of information on the net about 04.5 and 05 lly duramax truck that tow over 10000 have this issue. the major down side is the trucks inability to maintain the speed limit due to the 234* plus water temperature and the power loss formed a cooling fan that runs no stop when towing. i have made the same pull with my 2001 chevrolet duramax truck and have not had issues with impeding traffic flow.*ak
