Mishimoto Hi Everyone,

Thanks for your interest in our parts and I apologize for any trouble. The MMRAD-F2D-03 was an earlier version of the 6.0L radiator designed to be a more direct replacement for the factory unit that replaced the plastic end tanks with durable aluminum to help with longevity and heat dissipation. Since their initial release, we received feedback from drivers like many of you looking for higher performance options, which is where we developed the MMRAD-F2D-60, which features larger tanks and a thicker core for better cooling. The F2D-03 is no longer available directly from us, but we do still have plenty of drivers running it with no trouble, and they are still covered under our Lifetime Warranty for manufacturing defects.

If you have any questions or issues with either version of the 6.0L radiator or any of our other parts, feel free to reach out to our customer service team and we'll be happy to assist.

So, any one got a good idea on what to do with 3 large leaking aluminum radiators?

AL seems to be dropping around $0.80 in market pricing. Are you a Bull or a Bear?? LOL

Hopeless Diamond Actually, I've never heard of anyone having a problem with the OEM replacement. Business partner had one in his '13 for ~100k and no issues. I should have gone that way, but then look at all the fun I've had dealing with leaks...

Goldy The radiator in my 2015 F350 (yes...6.7) started to leak a bit around the lower drivers side around 58,xxx miles. I was not a happy campter. I replaced it with another Ford OEM radiator. After reading all the posts, I thought I was going to regret not going to the Mishmoto. However, the truck now as 185,xxx miles, and the Ford OEM radiator is hanging in there (no leaks)...knock on wood.

Good luck!

brazosdog02 Support contacted me. Looks like I’m on the hook for another 300 bucks if I want to roll the dice with the heavier unit. I don’t. Hopefully they will refund the cost of this because I fee like a huge idiot for thinking I was making a good decision and now they’ve admitted over email that the unit is not sufficient or to OEM standards. So...hope my engine holds out because they’ve left me in a huge lurch.

HeavyAssault Okay....I think they need to make things more complicated.

brazosdog02 Ok. Then I wait.

After I bought it I was told it was an OEM replacement. OEM is not light duty. This truck is bone stock other than oil cooler which actually takes more heat load off.

By the way, I’m mostly irritated at the circumstances since I thought I read awesome things about mishimoto and NEEDED a new radiator before a big haul.

HeavyAssault Here's their current excuses:

Hi @HeavyAssault ,

I received this customer's PM on Friday and forwarded their concerns to our customer service team. Our customer service team is not in the office over the weekend and we were off for the Labor Day Holiday.

The customer purchased the radiator off of Ebay, not from us directly, but we are doing what we can to help them. As I've said previously, the F2D-03 radiator is designed for light-duty/unmodified trucks and is not an outdated or old-stock product. We've reached out to our distributors to remove mentions of "performance" benefits from marketing information, but we cannot control how every seller communicates. Customer service should be getting back to this customer shortly.

Hopeless Diamond FWIW, the 3 Mishimoto radiators I went through (2 x version 1 and 1 x Version 2 - difference being the upper supports, aluminum vs. rubber) actually always cooled real well. As long as I kept replenishing the coolant that constantly leaked.

A few months into an XDP and so far so much better...

Anyone interested in some scrap aluminum?
