Product Details

  • Valve Assembly Water W
  • The water valve is a critical component of the cooling system, as it assures the radiator is functioning properly. The cooling system - and the radiator specifically - are important in maintaining safe temperatures in your vehicle. A malfunctioning radiator can compromise several other engine parts as uncontrolled engine heat will wear down heat sensitive engine components and sensors. It's important to replace your water valve with the proper parts, as cheap or aftermarket water valves can result in radiator malfunction and further engine damage. When your Toyota Prius needs a new water valve, use only OEM parts such as those found at Parts.OlatheToyota.com.

    Using OEM replacement parts insures your Toyota will run as the manufacturer intended. That means safety, reliability, and dependability every time. We don't "make up" for our low prices with shipping or other hidden costs. We can help you find the parts you need. All our operators have a minimum of ten years experience with Toyotas and are ready to answer your questions. Call or use our Parts Finder to place your order today.


  • Genuine OEM Toyota and Scion parts offer the same legendary quality as Toyota and Scion, with exacting standards that ensure proper fitment and function. Toyota and Scion warranty their new replacement parts from defects for 12 months or 12k miles, and all remanufactured parts for 12 months and unlimited miles.
