The Mishimoto Performance Aluminum Radiator for the Jeep Wrangler YJ and Jeep Wrangler TJ is the ideal upgrade to the stock Jeep Wrangler radiator. It is designed and specifically engineered to maximize cooling efficiency by up to 20%, boost engine functions, and protect your car from overheating. Whether you use your Jeep TJ or Jeep YJ for daily driving or as a powerhouse for off-roading, many people overlook the importance of installing an upgraded radiator in their engine. The stock radiator is unable handle the heat that comes along with having this much horsepower. The Mishimoto Jeep TJ radiator / Jeep YJ radiator features a lightweight dual core, 100% brazed aluminum, polished end tanks, and holds up to .36/gal more coolant. The Mishimoto Jeep Wrangler radiator showed a 20 degrees F drop in outlet temp compared to the OEM. See the Engineering Report for full details. Every Mishimoto Performance TJ and YJ Radiator is a direct OEM fit, making installation effortless on your Jeep Wrangler, with no cutting or modification required. All Mishimoto radiators come with a lifetime warranty.
It is a very fancy, well built radiator. My Jeep is my daily driver, I occasionally off road it, but had the extra cash around for this instead of another OEM one. Despite the somewhat negative reviews regarding leaks and warranty replacements that cost $50 to ship a new one to you, I have had mine installed for three months with no issues. I contacted Mishimoto to ask what those issues were about, they mentioned on Jeeps with AC, sometimes the metal to frame contacts were not remaining in place and cracking over time with severe off road use thus cracking the radiator itself. Their warranty is awesome, it even covers an accident that wasn't your fault, but you do have to pay shipping for the new one, I suppose this is fair given the ease of warranty. They told me new units ship (should ship so verify this with the seller prior to buying) rubber grommets in the six mounting locations to the frame. The catch is your original bolts are not long enough even though they say the original's will work...they won't. Even without the AC condenser in front of the radiator, you're way too short and have to come out of pocket for longer bolts which is the only reason I gave this four stars. For the price you pay, it should include the few cents worth of new hardware just in case. Again, Mishimoto said those grommets are only needed if you have the AC condenser in front of the radiator, so without it you can remove the grommets and mount it metal to frame. I used washers with a larger diameter to ensure the radiator can't move around either. Otherwise this thing looks and works just fine. No noticeable flow or temp difference, but it is all aluminum too which makes breakage less of an issue. Keep your engine flushed regularly!!!! Our 4.0's are notorious for rust build up. All in all, if you have the extra loot around it's a nice upgrade but I'm sure another OEM radiator would work just fine for another 140,000 miles.
I own a 2002 wrangler sport, manual with AC and 4.0L. Not exactly a "Direct Fit." Needs about 1/2" spacers to clear AC condenser due to the front fins not being flush welded. The bolts will not match thread count with Stock spring clips so it requires fender washers and nylon locknuts. This radiator does have cutouts for the AC unit but you will need a saw. You will need 3/8" plugs (2) for a manual jeep to fill the automatic trasmission holes, and a brass peccock to replace the drain cap. Owning a jeep I'm used to modifications so overall this is a good radiator.
This radiator is very well made. Great replacement part. However, the install is a pain. The screws supplied do not fit. The old screws are too small to work. Two of the 6 are nearly impossible to get out. Getting past the screw issues, the radiator works great. I am very happy with thisproduct.
My stock radiator has the quick disconnect transmission lines. Are there provisions for the quick disconnect lines on this radiator or do you make a radiator with them?

Hey Johnny, there is no difference in attachment so you quick disconnects will work. Thanks for your question.

I am replacing my old stock radiator with a new Mishimoto radiator. How many gallons of fluid will I need to fill the radiator and reservoir? (2001 TJ Sport)
Asked by Island Jeep from Key West on
Hi Island Jeep, You'll need 2 gallons of antifreeze for this Mishimoto radiator. Keep in mind not to fill the reservoir to the top, thanks for your inquiry.
