MotoRad Fail-Safe® Thermostats

MotoRad® Fail-Safe® thermostats are designed to help protect your engine when overheating occurs. Based on premium, patented technology, they offer superior protection to any other thermostat on the market.

Stage 1

Within normal operating temperatures, the Fail-Safe® operates the same as any other thermostat.

Stage 2

When overheating is caused by a deteriorated cooling system part, the Fail-Safe has a secondary stroke that activates a precision engineered piston that automatically locks the valve into a wide open position allowing coolant to circulate freely.

Don’t be stranded on the side of the road because your engine overheated and your conventional thermostat failed in the closed position, keeping coolant from flowing to the engine. Buy the best Thermostat on the market, the Fail-Safe® Thermostat from MotoRad®. Why is the Fail-Safe the best thermostat? Under normal operating temperatures, the Fail-Safe® operates in the same manner as a conventional thermostat.  However, when your vehicle overheats due to a deteriorating cooling system part, a standard thermostat locks in the closed position blocking the flow of coolant to the engine. Motorad’s patented Fail-Safe® Thermostat is the only thermostat that automatically locks in the open position, allowing coolant to circulate freely throughout the engine during the overheating process. This can protect your engine from a more costly repair. 

Once the Fail-Safe® thermostat does its job of allowing coolant to continue to flow to the engine during an overheating by locking in the open position, you must replace it with a new one.  There are standard thermostats, then there is the Motorad Fail-Safe® Thermostat. Ask for MotoRad®’s Fail-Safe® Thermostat the next time you need a new thermostat. 

MotoRad® thermostats meet or exceed O.E. standards and are 100% tested and calibrated for correct start-to-open temperature and maximum opening temperature.
