The gm 5.3l built between 2002 and 2006 using castek corporation engine heads were incorrectly built per gm and castek. the heads leak engine coolant into the combustion chambers and burns off causing the engine to overheat. gm has issued a technical bulletin regarding this issue and requests the heads be changed out but at the clients expense. with the loss of coolant and inevitable engine damage this is a safety hazard and should be a recall and replaced at gm cost. technical bulletin 06-06-01-019b issued 6/12/2007. | |||

2004 tahoe, 79,000 miles. engine overheated which could have caused fire if i had not noticed and stopped. gm dealer says overheaing due to crack in cylinder head and confirmed tsb 06-06-01-019b (06/12/2007) applies to vehicle, which admits there is known manufacturing defect in certain cylinder heads which can cause engine coolant to leak internally causing overheating and potential engine failure. dealer refuses to cover repair. i have pending complaint with gm customer service to pay for damage. i think this should be a recall as it can lead to overheating, engine failure and potential fire. there are multiple reports on internet of same problems by other owners. *tr | |||

2004 chevy tahoe with castech heads has a history of running hot or overheating with little warning. in the cooler months, will fail to heat the interior of the vehicle without warning. can leave drivers and passengers (likely children) without transportation in a harsh environment. | |||
10/15/2010 | 128000 | ||
The engine cylinder heads for the 5.3l gm motors built by castech leak coolant into the engine causing engine overheat and internal engine failures. gm has issued a technical bulletin #060601019b to address the issue and diagnose the issue. gm will not offer customers any financial help in the replacement of the defective parts. this issue effects the safety of the vehicle and the safety of the persons in and around the vehicle. the fouled engine oil causes the lifters to fail, the oil pressure to drop and the engine to lock up due to lack of lubrication by the fouled oil and the driver has no way of knowing this is happening as there is no external indicators. | |||

I have been hearing a rattling sound underneath my car while driving. also when i turn off the car, especially when the car has been driven for a while, i hear a popping noise, maybe from the muffler area. i was told today that the catalytic converter needs to be replaced. i bought the car new, so i don't understand how that could be already with only 85k on the car. *tr | |||
