Reviews for Mishimoto MMRAD-WRA-07V2 Aluminum Radiator for 07-18 Jeep Wrangler JK
Quadratec - please get rid of this product for your own sake! Mine failed after just over a year and about 12-13k miles. And that's better than lots of folks! The rad cap failed first at the 1yr mark, then 2-3 months later the radiator leaks on the bottom. Mfg is SLOW to get back to you on warranty claims too! This is just not a quality product. It's made in china not Japan like the name sounds and is just a waste of money...
Started dripping coolant after about 1.5 yrs after install, pulled radiator and could count four different spots where it was leaking. Ever since initial install I could always smell coolant but could never find leak (was leaking in fins).
Not worth the hassle.
I bought a Mishimoto Radiator for our Jeep wrangler in 2016. Within 6 months it leaked. They sent me a 2nd radiator. Within a year it started leaking. They sent me Liquid Chill Stop Leak. This band-aided the problem and also clogged my heater core. Another 6 months later, it started leaking again and it began gushing out, overheating my engine. Had to get a flat-bed tow. The "new and improved Gen-2" radiator was out of stock for 2 weeks so we had to put in a stock radiator. We are out hundreds of dollars and hours of wasted time from installing 2 of theirs plus a stock radiator to fix the problem. Do not waste your time or money. It is no better nor gives any cooler engine temps than a stock radiator.
Buy at your own risk!!! You have been warned!
On my 4th mishimoto radiator in 3 years. All have developed leaks near the top where the cores meet the tank, typically near the fill neck. Tested for electrolysis, all tested normal. Have flushed with distilled water, added anti-electrolysis additives, etc. No good. Mishimoto's solution is to add their own "bars" leak style fluid to my system. No thanks. Don't buy one. Waste of money and each replacement costs you shipping (approx. $70). DO NOT BUY.
2012 jku. replaced stock radiator with mishimoto about 4+ years ago now & has been fine. Not sure why others are having leak problems. Installation method? Had mine installed at a shop.
I have a 2004 Jeep TJ and a 2013 Jeep JK. I replace the radiators in both Jeep with mishimoto aluminum radiators. Shortly after installing about a month or so both radiator started to leak. I contacted mishimoto about the warranty and they were very helpful and sent me two new radiators. Again, a few months after installation both radiator started to leak. I never had the chance to take the Jeep's off-road. So the leaks begain with normal street use. I contacted Quadratec and they were very helpful and understanding they gave me a store credit without hesitation to buy stock radiators. This is why I'm a Quadratec repeat customer. I am sure that mishimoto makes quality products they could not offer a lifetime warranty on their products if they didn't. I think they need to design their off-road line, with the demands of off roading engineered into their product. The radiators installed into both Jeeps just as it should. Everything lined up just like a stock radiator would. The radiators look great in the Jeep. But if the performance is lagging then looks don't matter. I would only buy mishimoto radiator if the design was changed to make it stronger.
So 8 months into my new Mishimoto radiator and I have a bilateral leak, somewhat intermittent, but its blowing approximately three pints of coolant every 150 miles. Mish will warrantee the unit, but they charge you $30 to ship, plus they have some DocuSign charge authorization should they feel the warrantee claim is invalid. Lets just say I am kicking myself for not going back to OEM. Sure OEM broke, but at least I had 9 years of good use out of the thing. If you are like me (on the fence over this mod), skip it. Not worth the aggravation of their warrantee system.
I installed the radiator, it fit well looked great. about 2 weeks later I found out that it was leaking. I contacted the manufacture about it and they told me they would replace it free of charge. I just needed to send a pic of where it was leaking from. I spent several days after work trying to find the leak. I found that one of the welds was not all the way to the end of the tank, and when the fluid was hot and under pressure it would drip about 1 drop every 10 seconds. I shot a video of it and sent it in to them. I got an email later that day with a shipping confirmation. when the package arrived to my surprise they sent me stop leak. I called to question this and was told that they deemed that an appropriate fix. I will never buy this brand again because there life time warranty seams to not even be 6 months.
JUNK JUNK JUNK. first one that showed up to my house had bad brackets. mishimoto sent me a warranty replacement and that only lasted 2,000 miles until it started leaking at the core. good thing their warranty is good so you can replace your radiator once every few months...
