Re: Thermostat / hot climate driving

Not the way it works. If the thermostat is set for 190, then anything above that and the cooling system is at full flow/capacity. Putting a 160 thermostat in would just get it open sooner, then it would go to 210 eventually. You need a larger radiator. My truck never changes temp even with ac on full with 117* outside temp just sitting at a stop.
