Ha ha ha. Probably not. I just need a solution. I was looking at the flexalite but I don't want to have to swap the trans cooler. The only other "all aluminum" was the Griffin.

I'm super disappointed in the Mishimoto. The look is fantastic and the fit is great, but having my second one start leaking just a couple of weeks after install........

What are you wanting to accomplish? OE is probably sufficient for the vast majority of uses. Is it as blingy as an aftermarket? Obviously not, but "if it ain't broke"..
Griffin makes a high quality product, but again, what's the need/want?

bkundingerii

What do I want to accomplish? Well, for starters, to have a radiator that is reliable. The OEM nylon/aluminum ones are garbage. For that matter, so are the Mishimoto. So I guess I'm trying to accomplish having a reliable vehicle through quality parts.

Mine gave up the ghost at 160k, just went with OEM and local, $100, life time warranty. Thought about others, but it came down, reliability and down time. At least local I can take it out and swap. Online, I have to do a warranty request, the the new one shipped, just too much time.

My 15's radiator just gave up at 23k miles. It will be replaced with OEM under warranty. Once the warranty runs out and it fails again I will be looking at mishimoto product. I do run now of their radiators in my 95 Eclipse and it appears to be a great piece.

Looking at the point of failure on my oem radiator it seems to have started near the top on the driver side.

Had the same problem with the OEM at just about the same mileage. I know a bunch of people that had their OEM radiator take a dump before 30k (all of which are 2015/16 JKs. I think this is an "FCA/Jeep unacknowledged" problem with these model years.

I opted to not do a warranty claim and just changed it out with the Mishimoto. The thought was to put in a quality radiator that I wouldn't need to think about for a 100k miles or so. I've installed 2 of these Mishimotos now and have already submitted a "refund" claim for the second. They have a serious problem going on with these. I wouldn't recommend anyone buying these until they figure it out.

Fair enough. If the OE isn't doing it (haven't seen the amount of OE failures you have, I guess), sticking to an established, quality brand like Griffin should suit you.
I hope it's an RS/GS so the catastrophic failure it could cause is less catastrophic. 4g engines do not like heat.

Mishimoto

Hi bkundingerii,

I just wanted to apologize for the trouble you had with our radiator. Did our customer service ask you about your vehicle / its usage when you contacted them about the refund? We've noticed a lower failure rate within the 15/16 JK's so I'm curious to know more details. I'm also going to speak with the project manager and engineer on this to see if they may want to take a look at your failed radiators. I also wanted to reiterate that we have sold a good number of these radiators and the majority of them have not had issues; however, our customers' satisfaction is our highest priority so we're taking the failures that have occurred very seriously and looking for a solution.

As far as the Griffin radiator goes, we've fit our radiator on both the 3.6L JK and the 3.8L JK without any fitment issues, I would assume that the Griffin would be the same.

Sorry again for the inconvenience,

-Steve

Steve, according to Phomma in your customer service, and I quote,

"Mishimoto is not having any issues with these radiators nor are we aware of any quality issues involving our radiators and the Jeep JK".

So, assuming that this is the stance of Mishimoto's customer service, can you tell us all how many "lifetime warranty" replacements Mishimoto has sent out for P/N - MMRAD-WRA-07 over the past 12 months.

I think your customers would be happy to know this figure. I know I have now had two warranty claims in 4 months, and from this thread there are probably at least a dozen more.

I'd be happy to send my radiator back, tell me where you'd like it sent and pay me $30 (warranty replacement shipping cost) and I'll send it as soon as I remove it.

I'm not looking to get into a whole debate whether or not Mishimoto is producing a quality product, the proof is in the pudding (2 radiator failures in a combined 6000 miles). My time and the reliability of my vehicle is far more important than the $390 price that this product is selling for. I do not and will not accept a replacement for a third time. At this point if Mishimoto wants to save face, they should offer a refund for the receipt (proof necessary) amount should your customers deem that necessary.

To have to call your customer service have a debate about "if there is an issue" is piss poor.
