Fail Safe™ Series Thermostat with Seal (1C67CB) by MotoRad®. Temperature: 170F. Fail-Safe Thermostats offer premium, patented technology for superior protection over any thermostat on the market. Only Fail-Safe is designed to lock in the open position when overheating occurs due to a failing cooling system component. This allows maximum coolant flow, thus preventing expensive engine damage. Fail-Safe is designed to help protect your engine when overheating occurs. When overheating occurs, Fail-Safe automatically locks in the open position to permit maximum coolant flow. When standard thermostats fail, they lock in the closed position and prevent coolant flow to the engine, which can possibly cause serious damage to your engine. Fail-Safe has a patented safeguard against overheating damage. Fail-Safe thermostats are designed with a unique extra stroke that allows operation in two stages: Stage 1: Within normal operating temperatures, the Fail-Safe operates the same as any other thermostat. Stage 2: When overheating is caused by a deteriorating 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.
