I have a 2007 silverado 5.3 v8 auto trans 4x4 ext cab 6.6 box. I put a block heater in last year before I went to Fairbanks Alaska. Every time I plug in the truck at night in the moring before i started it it would have a error message saying truck is overheating turn of a/c. This is at minus 25deg out side temp the dealer said I need to take it back where I bought it for repairs. but no info on why I got that message?????![]()




Welcome to the site! The dealer told you to take it back? Have you exceeded the 36K mile bumper to bumper warranty? If not then it should be covered.

Did you purchase and install the OEM block heater? These new trucks are fancy to OEM goodies only. Anything else could create false error messages. Do you have the heater mounted where the fctory would install it?
