Years of research and development led to the advancement of the MotoRad failsafe thermostats from Wilson Manifolds. MotoRad failsafe thermostats utilize a unique and exclusive extra stroke that allows for operation in two stages. During stage 1, they will operate like any other thermostats. Stage 2 operation provides extra stroke and actually locks the thermostats open when overheating is encountered. These thermostats are constructed from stainless steel and include an integrated jiggle valve to help stabilize the pressure in the engine, reducing engine warm-up delay and eliminating trapped air in the cooling system. These are the first thermostats in use worldwide that will not fail. MotoRad failsafe thermostats from Wilson Manifolds are evidence of what is possible when technology and design unite. Get on the leading edge--get MotoRad failsafe thermostats.
