Good Fit
Great product for 2006 4.0 Mustang. Don’t know why Ford thought a plastic thermostat was a good idea. This fixed all coolant leak issues, and took less than an hour to replace. Plenty of good YouTube tutorials to watch 👍 Been on for over a month and no issues. GREAT value for money.

Comes with pre-installed thermostat.
Comes with pre-installed thermostat no need to buy one separately! Easy to install make sure you put some sealer on the gasket to keep it from falling off during installation. Seems to be very high-quality compared to OEM.

Good upgrade?
So far great no issues easy install. 30minutes and done. Seals well hoping seals hold up if so it beats the plastic model. Found old one worn and falling apart inside. So happy with this design.

Upgrade Thermostat Housing Works well
Fit well on our 2010 Mustang. No more coolant leak. Functions as advertised. Time will tell. Only just installed in Oct. 2025. Have about 50 miles on it so far.

Best Replacement, better than Stock Plastic one
This Aluminum replacement instead of your Junk Stock Plastic Part that keeps breaking, this is a no brainer!

Beats out the factory part by a mile!
Here's a part that beats out the stock factory part by a mile! Installation is pretty straight forward. It sure does make a big difference compared to the plastic part. Make sure you replace your hoses also!

La pieza está genial y es de excelente calidad; lo único por lo cual no doy 5 estrellas es que los tornillos originales quedan un poquito largos con la pieza nueva, tuve que poner 2 rondanas de presión por cada birlo para poder que apretara bien, de lo contrario quedaba suelta. Después de esto ya quedó muy bien y no tiene fugas, asimismo su desempeño es excelente. Le dejé el sensor nuevo y solamente reusé el termostato que relativamente lo había comprado hace poco tiempo. El carro anda excelente y valió la pena el cambio. Más seguro de metal que de plástico, la calidad es indiscutible y salta a la vista.
