| Description of the problem | The tahoe has known faulty castech cylinders which cause coolant to leak with no explanation. Over the winter i have had unexplained coolant/antifreeze issue with no found leaks (coolant would be bone dry after a couple weeks of filling it). I was told the issue is probably caused by the faulty porous cylinder heads made by castech installed in gm's from 2001 - 2006. This tahoe has a total of 80,000 miles now and experiencing issues due to known faulty parts installed by gm. Chevrolet has to be aware of the danger they are putting their customers in by not having a recall of a faulty part located in the engine. How there has not been a recall i do not understand. How chevrolet expect the customer to pay 3-4k to replace their faulty head is ludicrous. |
