Cooling like a champ
We decided to replace the thermostat with the water pump and it was fairly easy to remove and install. Working like a champ!

Perfect fit for 2013 Prius
Perfect thermostat replacement for 2013 Toyota Prius. Plug and play at its best!Was replacing the water pump on my 2013 Toyota Prius and decided to replace the thermostat at the same time. This is a perfect DIY project for the weekend.Was getting a P0117 engine code and decided to do an overhaul of the coolant system on my 2013 Toyota Prius. Replacing the water pump, thermostat, radiator expansion tank and coolant took me approx 1.5-2 hours.Save yourself some $$$ and get to know your vehicle a little better with this DIY project!
