- We first scanned for codes and found P0128 thermostat rationally. We then started the vehicle and monitored coolant temperature and found that in the driveway without the A/C on the engine would reach normal operating temperature, and the fans cycled according to specification. We then switched the A/C on and found that the engine coolant temperature would drop below specification. We then took the vehicle on a test drive and found that with the A/C off the coolant temperature would rise at a stop light, but when driving would drop below specification. Based on these findings it confirms that the thermostat is faulty. We recommend replacing the thermostat, and thermostat housing. Then test driving again after repairs.
