The turbocharger and intercooler cooling system is a water cooling system that is independent from the engine cooling system. It uses a dedicated radiator and electric water pump assembly to cool the intercooler and turbocharger. The electric water pump assembly uses duty cycle signals sent from the ECM to provide stepless, optimal control of the electric water pump assembly speed.
