Tuff Stuff High-Flow Thermostats

Tuff Stuff's High-Flow Thermostats flow 56 gallons per minute, almost a 50 percent increase in coolant flow over standard thermostats. These thermostats reduce the delay in engine warm-up times, allowing trapped air in the cooling system to escape and stabilizes the pressure of the cooling system overall. Also, a bypass valve allows a small amount of coolant to circulate before fully opening.

Features:

• Flows 56 gallons per minute
• Reduces the delay in engine warm-up times
• Bypass valve circulates a small amount of coolant before fully opening
• Available in 160° and 180°
