I have 07 torrent I just got due to overheating issue. I have done 4 equinoxes for heads and this is first torrent. start suv and get instant overheat message. And coolant gauge is Cold. Never moves. I get service stabilitrak, abs, tcs and even tpms system. And hot motor-ac is off. Been driving it for 3-4 days and motor is not overheating. So, is this a cluster issue and a ecm issue combined? Been told do NOT change cluster or I will have a security issue? True?
