Question about 2006 GMC Envoy
Howdy Steve. Well here are a few things I'd like you to check and do. First thing, did you have your oil changed recently, have you checked your oil level? Then my new friend look at the oil filler cap and look under it. If it looks like a malted shake under it you have a problem. Probably a blown head gasket. If this is or was the case your over temp light would have turned on. Have you had regular service done on your vehicle? Oil changes primarily. You could just have a bad oil sending unit. This would be the easiest fix. If your a little technical go to UTUBE and go into search location and removal of oil sending unit for your car. Remove positive cable on battery and disconnect and reconnect sensor connector. Reattach battery cable and restart car. Hopefully this will correct your problem. Let me know. Jim
