Tuff Stuff El Camino High Flow Thermostat, 180 Degrees 900180

These thermostats flow up to 56 gallons per minute, as compared to ordinary thermostats that flow 37 gallons per minute, to maintain stated temperature. The 50 percent increased coolant flow reduces the delay in engine warm-up times, allowing trapped air in the cooling system to escape and stabilize the pressure of the cooling system. The stainless steel construction with an extra-large center port assures increased coolant flow, and bridge design increases strength, stability & reliability and incorporates a bypass valve that allows a small amount of coolant to circulate before fully opening, assuring a fast warm-up. Ideal for high performance muscle cars, street rods and customs.
