MITZONE Upgrade Aluminum Coolant Thermostat Housing Assembly Compatible with Chevy Cruze 2011-2016 Trax Sonic 2012-2020 Buick Encore 2013-2019 1.4L Replace 25200455 55565336 902-808

I have a 2015 Chevy Cruz. At 70k, the water pump gave out. I replaced the factory thermostat with that repair with an aftermarket thermostat in a PVC housing. It cost me $80 at Autozone (OEM was $170). 25k miles later, and I had trouble again with the cooling system. When I took everything apart, I discovered that it was the thermostat that failed. The PVC housing became brittle, and cracked. Not wanting to make the same mistake twice, I found this thermostat with an aluminum housing for much less. It appears well made, and fit perfectly. I’ve put a few hundred miles on it, and it is functioning well and no signs of even the slightest leak. I’m extremely satisfied with this purchase!

I was skeptical at first from the other reviews. I have had a positive experience so far (~300 miles). The temps are great and no sign of sticking open/closed. No leaking at the mating surface or the radiator hose. For the price, the quality is surprisingly good. A nice looking (aluminum) addition to the engine bay removing the plastic thermostat housing. I will update if anything changes in the coming months. Will look to replace the other fail prone cooling components (Water Outlet etc.) as they show signs of failure.

Working good so far

I bought this after another one that I purchased on Amazon from another brand stuck open within 1000 miles (plastic version). The install is easy and includes gasket. Been going well now for about 1500 miles. I monitor temp via an app and ODBII adapter and this keeps the car a pretty constant temperature and opens when it’s supposed to. I do not notice that it’s running cooler as a result of the aluminum but it definitely looks better. I’ve also replaced the outlet on the other side with aluminum part as well.

DO NOT BUY! Construction is all metal as stated. It looks like it could have been a quality part. The machined surface that the hose clips to is about 0.2mm too small in diameter. It WILL leak. This product will not fit, will not work, will not hold pressure, will not assist in lower temperatures. Due to the ineptitude of the designer / machinist that made this part, the only thing that this part can and will do for your car is cause the cooling system to fail. This WILL cost you a lot of money if your engine overheats. Do not buy this product, avoid it like the plague. Complete and utter waste of time, money and resources.

Installed on a 2016 Chevy Sonic LTZ 1.4L Turbo . Fits just like the plastic factory one. I went with aluminum because the plastic ones can get brittle and crack and its really hard to find the leak. This one was easy to replace and seems to be well made. This is a complete assembly too, so no other parts needed. I would recommend also getting long reach Hose Clamp Pliers, as getting the clamp off and back on without one is a real PITA. I replaced mine after pressurizing the coolant system and spraying soapy water to find the leak.

Seems to be an ok part, the sensor plug was really tight getting the plug onto other than that so far so good ( hope I didn't jinx it) The factory part is plastic ( ok composite or plasitiglass) hoping the Alu last 100K ? Not a terrible job to do, 1/2 hr maybe ? I don't rush any more so I don't stress over time. Get yourself some torx sockets or be a hack and shove a 12 point on :(

the OEM plastic thermostat has flimsy plastic fingers inside that broke off, jammed the thermostat shut, and blew my head gasket. this solid aluminum part solved yet another of GM's major design flaws and now I have a great replacement part. mitzone guys should be supplying OEM factory parts to chevrolet.

este es el termostao adecuado para el cruze 2016 LT turbo 1.4 L

Excellent price and quick shipping.

After changing out to this thermostat, car (1.4l Turbo) threw up Code 89 persistently. Temperature gauge took longer than usual to reach its usual operating position. Turns out the sensor inside was faulty (according to my mechanic). If you want to upgrade your plastic housing, keep the original sensor and swap it into this aluminium housing.

A simple vista se ve de buen material. Pero presentaba fuga entre la cubierta metálica y el sensor a una semana de que se coloco. Compren mejor el original.

Great product and easy to install. Solved my overheating engine alarm.
