Dorman 926-959 Patented Upgraded Aluminum Engine Oil Filter Housing with Oil Cooler and Filter Compatible with Select Models (OE FIX)

I don’t often write reviews, but I had to for this one. I work as a mobile mechanic, and I get a lot of calls for failing oil coolers on Chrysler products — especially the 300s. The original oil cooler is notorious for leaks and a ton of related issues. Whenever I replace a failing cooler, I always look for quality parts is best compared or above OEM standards, and this one goes above and beyond. Not only do you get a complete aluminum oil cooler, but it also comes with the oil filter and intake manifold seals, replacement screws for installation, and a port plug for specific models — which alone would cost about $80–$90 separately. This kit was clearly made with mechanics in mind. It saves me time and money by including everything I need in one box, so I don’t have to make an extra trip to the parts store. If anything, I wish this came with injector seals but that’s me being picky. The included gaskets are high-quality, and the color-coded design with a card explaining the gasket change - a nice touch. The cooler performs better than the original and keeps temperatures lower. Installation-wise, the cooler itself is easy. The hard part is just getting to it. Once installed, it fits perfectly in the valley, and I’ve had no oil pressure issues at all - in all my time installing these units. If you want to save around $150, buy it online. And if you want to save yourself a headache, get the Dorman cooler. Trust me, this isn’t a job you’ll want to redo.

I replaced the old parts with these last well, and so far so good. In contrast to the original that I know lasted 90,000 miles. There wasn't even a problem with the old part except that it was a plastic item that the knit wit manufacturer had placed inside the engine that I was advised to be rid of. I don't know how long these will last. We'll just have to wait and see. But thus far thus good.

have a damn solid mechanic. I thought I had a leak — I did not — but since this part is recommended to be replaced every 36k–50k miles and my Mojave was at about 50k, I opted in. I did quite a bit of research on this product. First off, most are made in the same factory in China but go through extensively different quality control processes. This includes Dorman and Mishimoto. I can’t say how many factories or which makes which, but know they are all made there. The biggest difference is the aluminum oil reservoir — some are made differently, and they don’t all sit well. Dorman’s unanimously has the best seal. That said, you really should use Mopar and Fel-Pro Viton seals — they are the blue and green ones. The red Viton are not as good and have failure issues. Also, use Mopar O-rings, use Mopar sensors, and use orange threadlocker — it’s a bridge between blue and red, literally made for stuff like this. Lastly, pay attention to torque specs on the cap — that’s the biggest failure point for the Dorman. The “best” fix is to couple it with a Baxter adapter, but that’s another ~$400, and those are debatable. The most important thing is to follow the torque specs and don’t over-torque the cap — over-torquing compresses the O-ring, which is where most failures occur. It’s not an easy job. Each part has different torque specs, and most reported failures are due to user error and incorrect torquing. If you don’t have the proper tools, buy the part, buy the seals and sensors I mentioned, and bring it to a shop that charges hourly. Use a Wix XP filter and Mobil 1 High Performance oil. The shop I took mine to installs these regularly. I wasn’t the only one there that day, but I was the only person who brought the full kit I specified, and the mechanic was very impressed and stoked because all he had to do was build and install it. Look — it’s a great quality product that is built to fit perfectly, keep oil pressure at the correct levels, and serve as an OEM replacement. It’s covered by warranty as long as you follow OEM installation guidelines.

I'm giving this 5 stars at present because so far, with only about 50 miles and about maybe an hour on it since the install, it appears there's no leaks. I've read some not so good reviews on the Dorman version of this oil filter/cooler unit and have read some good ones. Before the installation, I did a very thorough inspection of this unit BECAUSE of some complaints I'd read about concerning poor quality and machining. Well, I found no issues, no poor machining, no "burrs", no rough edges or any other potential flaws or issues. I checked all flat surfaces with a straight edge and all were/are dead flat with no bridging, concave or convex appearances. Some complain that the oil cooler needs to be assembled to the oil filter housing prior to installing the unit as a whole. Yes, SO WHAT! Big deal! I actually prefer that kind of scenario. You get to see the fit and finish of those two components prior to the install. And, by doing it yourself, you determine the actual torque of the fasteners, not anyone else. 'Nough said. I installed all O-rings and seals per any instructions, made dang sure all surfaces were sparkling clean and then installed the complete unit into the engine valley with the supplied fasteners. I evenly torqued all fasteners in the appropriate pattern all the way to the final torque spec. So far, I'm very happy with this Dorman aluminum oil filter/cooler housing. Time will tell.

Anyone needing to replace their oil cooler should look no further then the Dorman. It has a great reputation for a reason. It was easy to install and I have had no more issues. Solid Product

Seemed to be very good quality and was a far superior replacement compared to the oem oil cooler and it came with all the gaskets you need for the job.

The original Mopar filter housing lasted 12 years and 80k miles on my 2013 Jeep JK. I was hesitant to install the plastic Mopar one, since they did not upgrade it for the 2013 engine design, so I went with this one after heavily researching it. The Dorman one lasted about 5 months and 5k miles. I was very careful to install it all correctly, paying close attention to seating the seals (a little oil applied prior to installing), the torque sequence, and the torque settings. I read several reviews where people had the same issue with it leaking after a short time. I should have listened because this project is not fun to do. Well I'll be back at it next week, this time I'm going to keep my fingers crossed and install the new Fel-Pro OFHA1001. I should have used Fel-Pro seals with the Dorman, but I was not 100% certain they were compatible with the Droman unit sizewise. The new Fel-Pro design is a vast improvement over both the Mopar and the Dorman, they do not use the figure 8 seal under the cooler. The biggest thing for me is the Fel-Pro unit comes with the cooler installed and is the seals are perfectly designed for it. I sure hope I don't have to do this project the third time, if so I'm just going to go back to the Mopar one. I believe the Dorman's failure is solely due to their subpar seals and not so precise casting. Check out the Fel-Pro OFHA1001, there are not a lot of reviews on it yet as it just became available in August of 2026 I believe, but this information makes me feel a bit more confident: "Real-World Fleet Miles: Fel-Pro logs over 1.5 million test miles annually on real vehicles before releasing components to ensure a 100% leakproof seal." That and Fel-Pro's excellent reputation and superior seal technology, though I'm going to put the Mopar oil pressure and temperature sensors that I just installed on the Dorman on the Fel-Pro as Jeeps appear to be super sensitive to aftermarket sensors. Time will tell how reliable it is, but I would definitely would not go with the Dorman. I don't think I'll ever purchase any Dorman products for my vehicles, or purchase auto parts off of Amazon, ever again. *I was worried about getting a counterfeit Dorman oil filter housing from Amazon (made sure it was sold by Amazon and not a third party). I closely looked it over after receiving it and compared to one from a local auto parts store and it was dead on. So I'm fairly confident the one I received was a legitimate Dorman product. **I will return to this review and remove all reference to the Fel-Pro if I have any issues with it. If this review is up the Fel-Pro is still going strong. One more thing to note, the Fel-Pro unit looks premium compared to the Dorman. The casting is smooth and looks like so much more time and care went into the design and manufacturing processes. That is already making me feel more confident, plus the included intake seals straight look and feel more durable. I included pictures of the new Fel-Pro unit.

There’s like a 95% chance you’re looking at this because your oil cooler housing on your Mopar with the Pentastar is either failing, cracked, or leaking. All in all, this is a fantastic upgrade that I seriously wished was from the factory. Installation was absolutely painful for beginners or those who aren’t too mechanically inclined, but is definitely worth doing the change. Anyways, the Dorman oil cooler housing is metallic instead of the OEM plastic, which is rather obvious given that the OEM one is black and metal being metal, is silver. Oil pressure is the same, functions really smoothly, and fits exactly the same as a new OEM oil cooler housing from Mopar. Now the caveats were that the included seals were and are trash, so I went and got the OEM seals for it, same goes for the included oil filter. Installed on my 2014 Jeep Cherokee KL Limited V6 4x4 and after running it for over two months now, this was easily one of the best maintenance things I’ve ever done.

Excellent value.

The product is made in Malaysia and is of low quality. Why was it not made clear that it was made in Malaysia? I want American made. In general, the quality is bad. There is no professionalism in the final appearance. Aluminum alloy inserts are not equal and I do not recommend purchasing them.

De muy alta calidad, bien fabricado y con un kit súper completo, queda perfecto en mi vehículo

After smelling a strong odour coming through my heater vents, I initially thought the exhaust was leaking but the pools of oil rapidly forming under the car let me to research leaks on the Grand Caravan, and this became the number one culprit. I watched a bunch of videos online about how to replace this, and as a fairly competent home mechanic with basic level tools I took my time, checked and double checked everything, and had the whole thing done in probably 3-4 hours outdoors on the driveway. It's been a week and no more smells or oil leaks. It's not the cheapest replacement part, but the quality appears to be good, and there is some basic assembly required so make sure you have all the tools before you start. A lb-in torque wrench is a good idea if you want to be precise as well as something like water pump pliers or hoseclip removal pliers. Car trim removal tools proved really useful for loosening old hoses. Also, I'd recommend getting an oil transfer/extractor syringe that will make light work of cleaning out most of the pooled oil that will have collected in the valley between the cylinder banks. Much better than soaking it up with paper towels. In some online guides they will instruct you to remove the fuel hose from the injector manifold - i found it easier and quicker to remove the airbox, leave the fuel rail connected and simply flip the injector manifold over to where the airbox used to be.
