Cooling system
Whenever the ambient temp falls below70 degrees the temperture gauage falls to 0 and the DIC displays "engine hot air conditioner off" but the oil temp shows the correct temp 150-180 and the motor is obviously cool. Chevy says the problem is in the thermostat that it should be 212 instead of 160. The tuner says they don't want it to run
hot for performance sake. WHATS UP WITH THIS?
