Dude I got mine for 100 bucks from quadratec for my 96 xj. Its been a year and so far so good. I recommend it.

[@NBHRaven]

Love the how to! Perfect for getting mine installed on my 95 2 door XJ! Can’t wait to finish putting the radiator support back in and adding coolant! 😁😎

[@dbizm]

This will be my next upgrade after the radiator I just installed fails.

[@ryansmith4717]

I’ve seen a lot of good reviews on this radiator so I got it and replaced mine but this thing has been nothing but problems for me my jeep has been overheating and running hot at times I installed everything right aswell not sure what it could be

[@mishimoto]

Sorry to hear that you have been running into issues with this, please feel free to reach out to our customer service team at [e-mail] and we would be happy to help out.

[@fabguy276]

Likewise. Try a high flow water pump. The increased volume of this radiator causes a pressure drop and won’t cool better with a stock water pump.

[@jhatfield2755]

Have you tried doing a coolant flush and purging air out of your system

[@pra3t0rian]

Looks like a great option for when doing a V8 swap.

[@robertcoia130]

Is that a Deep Amethyst colored Jeep? Nice color, you don't see too many of those around.

[@hectorgarcia1941]

My xj is a manual transmission. Do this radiator comes with plugs to cover the transmission line port.

[@mishimoto]

It does not, however, plugs are not necessary.

[@hectorgarcia1941]

@@mishimoto thanks going to upgrade to mishimoto pretty soon.

[@davidcatalina6029]

@@mishimotoI just purchased my radiator for my xj. To clarify I won’t need to get plugs if my xj is a manual? Please explain how

[@shanesaw13]

@davidcatalina6029 The ATF side and coolant side are separate, so plugging it will only seal the ATF-side from outside air.

[@ninjetti]

I guess Ill try this one next... I just installed my third aluminum from a third company and it started leaking too.

[@williamchristy257]

Need an all aluminum for the WJ ):

[@jakewaybright973]

Will this Work with a WJ jeep?

[@mishimoto]

We have not tested this in the WJ Jeep. Sorry!

[@LuisRamirez-so1un]

Will this work for my 88 Jeep comanche ?

[@mishimoto]

Unfortunately, this does not appear to be compatible with the 88 Jeep Comanche. Sorry!

I called 1.877.GOMISHI
and the sales rep said it would fit perfectly. Should I not get it ??

[@gui577b]

Yes. The front clip/radiator are identical to the XJ. It would be a good idea to convert to the open system though.

[@bungcheese5901]

All this great manufacturing and information and you guys have the lightbar on the hood. Losing like 75% of your photons there pal :(

[@mishimoto]

Hey, bung cheese. All vehicles featured in our installation guides are provided to us by generous customers. While that position may not be ideal, we were only granted permission for the radiator install :).

[@bungcheese5901]

Mishimoto Automotive 😁👍

[@danhambrick6331]

That is one slick radiator.The XJ is nice too.The only thing wrong here is that stupid light bar on the hood.Is that some kind of joke?

[@mishimoto]

This is something that the owner of the jeep felt was needed when taking the jeep off-road.
