It fit perfectly and is much better than the original housing and for the price, you really can’t beat it.

I had a 2015 chevy sonic ltz sedan. I wish I knew that having a metal housing was an option because I went through 3 plastic OEM housings through the life of my car before I finally saw this one and installed it. The original part is garbage it WILL crack on you as it did for me and pretty much any other sonic owner. There are a ton of threads on how terrible the plastic parts are and that you should immediately swap it out for an aluminum one like this one. Do yourself a favor and save yourself car troubles by just replacing your housing even if yours isn't cracked yet, with this one. It was easy to install, I don't know much about cars or working on them and even I was able to crash course through the installation process. Good part, did its job, didn't leak, and was able to get my car back up and running just in time to trade it in for the new one I have now. 10 out of 10 would buy this thermostat housing.

Used this but used felpro gasket since I had purchased timing cover set and was included. Fit was spot on. No leaks. Only thing I noticed was the air bleed check back was at 6 o'clock position then o'clock location. I was able to undo spring plate and move to that position, then installed it. Worked well with computer as no codes. If I have issue later I will update. Great price and not plastic. Hardest part is heater hose clamp and hose install but well worth time to do locked radiator hose in place perfectly.

I had an issue where my car was overheating; the coolant and oil temperatures were reading over 240*F, and my A/C wasn't working. After looking more into the issue I learned that my thermostat was stuck "open", which meant it had failed. I decided to get this instead of the OEM part because it is not made out of plastic for my Gen 1 2016 Chevy Cruze LT, and it fits perfectly. It was a pain to install because my hands don't fit very well in small places, but I still managed.Fixed my Issue with the thermostat and overheating but not the A/C issue; it turns out the A/C clutch is ALSO bad...But at least my car is running better now with this new part.

Better than the plastic ones you get at the local parts store and a lot cheaper to pay for

Failed after 400 miles.Ii gets stuck in either the open position or closed position. Either the engine runs too cold because of constant flow, or sometimes no flow of coolant whatsoever so it runs hot, but shows it is cold. Very dangerous. If I didn’t know better I could have totaled my engine. Terrible temperature control. Sure the aluminum is a better material, but leave it to the functional design to fail with these crappy Chinese “upgrades”. I’m waiting for the OEM part to come to install a replacement and I will be returning this junk.

This part actually made my engine temps go down quite a bit! I guess the aluminum has better heat dissipation than the stock plastic part.

installed on my buick encore 2016 to acdelco water pump i usedFEL-PRO 35981 Thermostat Gasket instead of the original gasket and put rtv gasket sealant on it i’ll update if any problems occurs so far nothing 8/29/2025
