If your car is leaking coolant around the thermostat, or one of the connector tubes on your thermostat housing is broken or cracked, then this could be your solution.


  • Direct replacement
  • Includes thermostat and o-ring as shown
  • Built to strict quality control standards
  • Correct for models without housing-mounted cooling sensor

Over time from thermal expansion and contraction the mating surfaces on the housing can warp or crack. You may also find if you go to change the thermostat the 2 halves of the housing will not come apart. If you are experiencing any of these issues replace your thermostat housing with our direct replacement part.

This website is great.
When shopping for this part I called all around my local auto part stores. And they were all at least double the price and I would have to wait a week for them to receive the item. This was very easy very fast shipping and a good quality product. They even had a video of what I should do to exchange it. I highly recommend this website and will definitely be a return customer.
