Description

The original coolant thermostat housing assembly on certain Chrysler, Dodge, Jeep, Ram and Volkswagen vehicles is made from plastic that becomes brittle over time, eventually leading to cracks. In addition, overtightening the bleeder valve can cause fluid leaks that can damage the cooling system. This Dorman OE FIX thermostat housing assembly is manufactured from aluminum to help provide increased cooling system protection, and features patented design upgrades that optimize coolant flow and heat transfer. This part is compatible with the following vehicles. Before purchasing, enter your vehicle trim in the garage tool to confirm fitment.

    • Cooler Range than Stock 2012 Chrysler Town & Country
I think that’s a good thing!! Our Chrysler T&C was throwing an occasional check engine light for low coolant temperature, P0128. Checking the dash selection for coolant temp on trips showed it was running 168-175. Checking the internet found that stock thermostats which sit in a plastic housing operate from 203-215 (95C) Quite a few owners were writing that they wished it was cooler running. There is a performance thermostat available for the Pentastar 3.6l that is set to open at 180. Our problem was getting to temperature, our towing with this vehicle is rare and didn’t want to see a CEL any more I did not want to go that low. This aluminum housing has a thermostat that is stamped 90. Operating temps from the dash computer show the engine is running 185-194 and I saw 197 once while parked & running in the driveway after a trip when visually checking fluid level. Installation in my driveway was about 70-90 minutes. I put a big plastic under bed sweater storage bin under the front of the van to catch fluid, disconnected hoses and unbolted the plastic housing one. Put this in place and secured it with the machine screws like the previous was. The thermostat in the original was stuck open upon inspection. The bleeder screw in the new aluminum housing is correctly oriented upwards when mounted on this engine. I added new 50/50 mix G05 fluid to the radiator and plastic tank while squeezing the hoses. Rather than bleed it I put the container of antifreeze in the van and drove it for short trips, like up to 10 miles with the dash computer set to show coolant temp. Over then week I added fluid three times in the tank, not much each, and it stabilized. Van runs great. Drove 3000 miles from MI to CO and the mountain ski areas with no issues and I downshift to engine brake on grades. No codes or check engine light and temp is consistently running 190 plus/minus 5. ... show more

    • Great replacement for common leak on pentastar 3.2/3.6
Installed on my 2014 3.2 Jeep Cherokee that had a leaking plastic thermostat at the seam. This aluminum part is what FCA should have used from the factory on something that handles hot coolant from the engine. Easy to install just make sure you have the factory Mopar OAT coolant on hand since you will spill some and need to replace it bleed the system etc. Have the dorman aluminum oil cooler and coolant crossover installed on my Jeep as well to replace the weak failure parts of the engine. ... show more

DO NOT BUY! Unit failed just past the 30-day return window. It stuck open, causing an expensive repair. Not recommended.

While changing out the upper/lower hoses and radiator, the original plastic thermostat housing cover started to leak. Discovered a crack in the housing from overtighening. This upgraded replacement thermostat cover is a perfect fit for the original plastic cover. Installed in minutes, no leaks. 2017 Ram Promaster 1500. ... show more

    • Premature Failure, But Excellent Customer Service
I’m disappointed with the premature failure of the Dorman 902-3036XD Thermostat Housing, but I do want to give credit where it’s due regarding customer service. I purchased this thermostat housing in January 2025 for my 2015 Chrysler Town & Country 3.6L, and by May 12, 2026, it had already failed. I noticed engine temperatures climbing as high as 240°F. After checking for coolant leaks and confirming the coolant level was full, I removed the housing and performed a boil test. Even after heating the water to approximately 240°F, the thermostat remained completely closed and never opened. A thermostat failing in the closed position is a serious issue that can quickly lead to overheating and possible engine damage, so I was very concerned about the reliability of the product. That said, after contacting Dorman Products, they did stand behind their product and promptly sent me a replacement unit. While I’m unhappy the original part failed after only about 16 months, I do appreciate their customer support and willingness to resolve the issue. ... show more

    • Buy it for the housing but throw the thermost away and get a good one.
OK. I'm trying to be fair. The thermostat itself is absolutely trash and should never be installed on a car. Having said that, the housing is absolutely awesome. I love the housing. I love that it is aluminum, can handle torque, and that the bleeder works. This assembly has been installed on our 2014 T&C Limited since June of 2024. We've had a lot of weird fluctuations with our temperature gauge ever since, but we had a ton of other work done at the same time and it wasn't bad enough to really think the thermostat was the problem. That changed somewhat recently (April/May 2026) when the temperature gauge started reaching the 5/8 line, and at times the 3/4 line. BTW, I was graphing the coolant temperature on Alfa OBD while driving it and the 5/8 line corresponds to the max normal operating temperature on this van. The 3/4 line significantly higher than the max coolant temp range (like pull over and let it cool down high). With all that said, I would recommend the housing itslef without hesitation. It looks good. It works great. The bleeder works really well on it. And, it accepts the stock thermostat (which it should) so you don't have to worry about buying a different part number thermostat like you do with their aluminum oil cooler/filter housing. All in all, I recommend buying it but knowing that you're going to also have to buy the thermostat from a different (trusted) manufacturer. Look. If the thermostat wasn't garbage, this would easily be a 5 star review. But because of that, I wavered between a 2 and 3 star review. I landed on 2 star because I had to do the work of replacing it twice. ... show more
