Good To Know

Q: Why does an electric water pump matter on a hybrid? A: Hybrid cooling circuits need coolant flow even when the engine is off, so the pump runs on electric power rather than a belt. A failed pump can trigger overheating or hybrid system warnings.

Q: Do I need to bleed the cooling system after installation? A: Yes, trapped air can cause hot spots and false overheating readings. Follow the manufacturer bleed procedure for the specific model after fitting the new pump.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
