Electrical Coolant Pump

Critical For Operation

Cooling System

Uses an electric motor to force coolant circulation through the engine cooling passages and radiator, maintaining engine temperature and preventing overheating independent of engine speed.

The electrical coolant pump is an electronically controlled alternative to belt-driven mechanical pumps, used primarily in hybrid vehicles and some modern engines. It circulates coolant through the engine block and radiator to maintain optimal operating temperature. Because it runs on electric power rather than engine power, it can operate independently and improve fuel efficiency.
