For 04-09 Toyota Prius 1.5L Engine Electric Inverter Cooler Water Pump Assembly

Electric Inverter Cooler Water Pump Assembly for Toyota Prius

This electric inverter cooler water pump assembly for Toyota Prius circulates coolant through the hybrid inverter cooling circuit to keep power electronics within safe operating temperature.

Overview

This electric inverter cooler water pump assembly is designed for 2004 to 2009 Toyota Prius models equipped with the 1.5L hybrid powertrain. The inverter water pump assembly moves coolant through the inverter cooling loop, helping protect the hybrid system electronics from heat buildup during operation. This inverter cooler water pump assembly suits owners replacing a failed or noisy unit on a second generation Prius.

Good To Know

Q: Does this pump require a special coolant? A: Hybrid inverter circuits typically use a dedicated coolant type, so check the owner or service manual before filling. Using the wrong coolant can affect pump life and cooling performance.

Q: Can a bad inverter pump trigger warning lights? A: Yes, a failing inverter cooler water pump can set hybrid system codes and cause power reduction. Replacing the pump and refilling the circuit usually resolves the issue.

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