Perfect fit and replacement for 99 Jeep Cherokee XJ
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.

Bought this for my ZJ 95 Jeep. I was very happy with this purchase.
First pic shows the coolant housing before I painted it. Looks good but I decided to paint mine.
Second and third pics shows comparison to my original OEM pulled off my jeep. I am happy with quality and how it is made same as OEM, except I did notice in the second pic that the large opening is slightly different but possibly better as well. Last picture shows completed install.
I am very satisfied with this, no leaks, no imperfections, no defects, no cracks, clean, and easy install with the proper knowledge to do so. Highly recommend this to all and saved me time from cleaning up my old one.

5.0 out of 5 stars It fit but you should probably get the FelPro gasket.
Reviewed in the United States on November 29, 2023
Capacity: 1 Count (Pack of 1)Verified Purchase
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.

Got it as an insurance policy id I over tightened the OE one. I didnt so its staying in the cabinet for a later time if needed. Used the gasket with an incorrect stat so cant just send them back and not worth the trouble to just buy a separate gasket for $9 to mail it back for $11 dollars.

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.
