FEATURED PRODUCT

THERMOSTATS

Designed to exceed original equipment specifications • High-grade triple bridge design for strength and stability • Enlarged opening to provide increased flow • Superior response to cooling needs

When a deteriorating cooling system part causes overheating, this thermostat has a secondary stroke that activates a precision engineered piston. This automatically locks the valve into a wide open position to allow coolant to circulate freely.
