Thermostats

This SPECIAL or extra performance thermostat is designed for the customer that requires additional coolant flow through the cooling system. It is considered a balanced sleeve designed thermostat.
Because of its unique three port construction, the balanced sleeve thermostat equalizes the system pressures above and below the thermostat’s moving valve. Therefore the thermostat is pressure balanced and will respond to system temperatures only. It provides the customer a thermostat with a fast temperature response time and increased coolant flow to the radiator.
Customers who will benefit from increased coolant flow, such as those with:
Heavy duty vehicles
Trailer towing vehicles
High performance vehicles
