Enhance Prius Heating and Engine Cooling with FILTERUP 16670-21010 Coolant Control Valve Assembly

Designed to fit Toyota Prius models from 2004 through 2009 with a 1.5L L4 engine, the FILTERUP coolant control valve replaces the heater control valve and precisely manages how coolant flows to the heater core. The included bracket helps ensure a secure, factory-like fit and clean installation.

What it does

The valve governs the path of coolant from the engine to the heater core, which in turn modulates the heater output and the balance of engine cooling. By actively controlling the flow, the Water Valve Assembly supports responsive cabin warmth and consistent cooling when needed.
