Under extreme heat conditions like on the racetrack, or on the open road in high-ambient temperature areas like Florida or Texas, engines are susceptible to overheating failures – such as upper radiator hose outlet break-off or cracking of plastic thermostat housing. Bad news, every time.
A lower degree thermostat helps the engine run cooler from the start, reaching operational temperature earlier to enhance circulation and dissipate heat. The net effect is reduced thermal stress on the entire cooling system.
NOTE: This device is only recommended for use in racing or torrid ambient temperature conditions. Installation in colder climates may render the heating system to be inoperative, or slow to activate, and is not recommended.
