Tuff Stuff High Flow Thermostat - 180°F (TUF900180)

Standard thermostats flow about 37 gallons of coolant per minute. With Tuff Stuff's High-Flow thermostat, that number jumps to 56 gallons perminute. That's almost a 50 percent increase in coolant flow! The increased coolant flow will reduce the delay in engine warm-up times, allows trapped air in the cooling system to escape and stabilizes the pressure of thecooling system overall. These thermostats also have a bypassvalve that allows a small amount of coolant to circulatebefore fully opening.
