Dorman 902-306 Engine Coolant Thermostat Housing

Perfect fit on 2000 Jeep cherokee XJ. No leaks, affordable, easy install and looks much better than the old crusty one it replaced.

Great price! So much easier to just install a ew water-neck. You don’t have to razor off any old gaskets or deal with cleaning the hard water off the old one. Everything transferred over perfectly. Had zero issues. Looks good too! Comes with a gasket.

Factory fit and finish. No surprises. Direct replacement on my Jeep 4.0

The angle is slightly sharper thannin OEM, so it depends on your mounting position and valve cover if it will work out the box, I had to fit the hoses before bolting it in to ensure no leaks.

I purchased this thermostat housing due to my old housing looking a bit worse for wear. Installation was straight forward and the supplied gasket provided a leak free replacement. Make sure the gasket surface is clean from old gasket material. In my case the old housing had a RTV gasket from the previous owner so a wire wheel was necessary. Remember to torque the bolts appropriately when installing and there should not be any issues with cracking / malfunctions. Thermostat torque specs : 13 ft lbs (156 in lbs) I replaced almost my entire cooling system when this was done. Links to other compatible parts below.

I had to do a coolant system refurb on my Jeep WJ 4.0. The main problem was a worn out fan clutch but it was leaking around the water pump too. I did the "while you're in there's" too so water pump, fan clutch, thermostat, thermostat housing, heater hose pipe and Fel-Pro upgraded gaskets with Honda-Bond RTV Silicone sealant and a new serpentine belt too. Everything worked great but to get the old fan clutch off I had to cut the nut part that screws on to the water pump shaft. I used a new Milwaukee M18 Orbital Super Sawzall, my reward for doing this DIY job. I didn't want to buy the Sawzall but after trying two parts store rental fan clutch removal tools with absolutely zero success, I got medieval on it. 15 minutes and two saw blades later the repair could proceed. The lower fan shroud fasteners are another pain in the ass for that job but after that, no big deal. After carefully cleaning all of the gasket surfaces and applying a reasonable amount of Hondabond, everything reassembled easily, I put the old hoses back in place refilled the system and burped it. Now my engine temperature stays right at 195 I think and beside warming up, the needle never budges. Before it would overheat if I wasn't traveling at 45mph+ and I had to add coolant almost every time I drove. That was mostly the fan clutch causing that but everything I used to fix it is working perfectly so far.

It fits just fine

Works on my 2001 Jeep WJ inline 6. Exact fit to OEM. Make sure you get a Felpro gasket instead of one that comes with it. Gasket does not feel sturdy and may leak in the future.

Replaced the thermostat in my Jeep Wrangler TJ, 4.0l. The old one was the O.G. factory and was well knackered. This was a drop-in replacement, the quality is as good as the factory one. It came with a decent gasket, which I made very good with gasket compound (gray). I took the opportunity to replace the thermostat, upper & lower radiator hoses and the water temperature sensor; it's now running consistently 7-10 centigrade cooler. I am very happy to recommend it based on the short time I have been using it. I expect it to last a decent amount of time based on the high quality materials used and the engineering quality.
