Dayton-Phoenix is the OEM for the engine protectors, which translates to a best-in-class part with life-cycle cost reductions for you. Our engine protectors will exceed maintenance overhaul schedules to provide years of field-proven reliability.

We manufacture 1, 2, and 3 button engine protectors. The 1 button is often referred to as a crankcase monitor. The 2 button, also referred to as the engine protector, protects the water pump and engine air pressure. The 3 button, also called the engine protector, protects both water pumps and monitors and shifts down the engine if there is a change in air pressure.
