Water pump shafts circulate coolant though the engine block to maintain engine temperature.
Our cooling systems are designed and tested to ensure that your engines are operating at the most efficient temperature.
Only about 33% of the total heat from burning fuel in your engine is converted into crankshaft horsepower. Approximately 30% is expelled through exhaust, while another 7% is radiated directly into the atmosphere from engine surfaces. The remaining 30% must be dissipated through a carefully designed cooling system, which is where we come in.
Our cooling systems are manufactured to ensure that they remove just the right amount of heat to in order to keep the engine at the correct operating temperature.
