    • Functionally identical to OEM model
Matched the old OEM version very closely in appearance during install, did this as preventive maintenance while swapping fatigued water pump. It has only been a few days but so far, very pleased & no concerns.

    • This part made the leak worse than before
I installed this part on my 2011 Prius to specified torque settings and not sure if ithe part was damaged but when I tried it out coolant was spilling out of the thermostat. Definitely recommend going OEM for this part. Same goes for the water pump

OEM quality, bought it for a 2013 Toyota Prius. It was a perfect fit, great quality and installed easily. It's been working perfect. Make sure to change this when you do the water pump.
