Tuff Stuff 900195 Supercool 195 Degree High Flow Thermostat

Standard thermostats flow about 37 gallons of coolant per minute. With Tuff Stuff's High-Flow thermostat, that number jumps to 56 gallons per minute. 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 the cooling system overall. These thermostats also have a bypass valve that allows a small amount of coolant to circulate before fully opening.
