Mishimoto 1999-2014 GMT800/900 Performance Radiator R&D

[Mishimoto]

Who are your distributors?

We have quite a few (Googling the part number from the product page usually brings up any that carry it). For this rad and most of our domestic vehicle products, JEGS and Summit Racing are two of our larger distributors.

Thanks!

That’s a stupid comment to make with absolutely no context or relevant information regarding why.

I’ve had mine installed in my 2007 Yukon Denali for a few years now with no problems. Works much better than the OEM one and I have not had any issues at all.

*I should add that I purchased it direct from Mishimoto... Reach out to them and they will provide you with a discount. I paid $475 shipped w/ taxes. I believe it was a 10% discount.

Just like everything, that price has gone up since I purchased mine in 2020 from
summit racing.(thanks alot fjb) Make sure to buy from a reputable place and take a pic of the
serial number for future reference. If you do need any warranty, you won't have to
remove a bunch of stuff to get the number.

Mine has started to leak after 14 months of use. It is leaking from the driver's side towards the top, not sure if it's the main weld or at core. Gotta have to pull my fans to pinpoint the leak

I wish they were that inexpensive, unfortunately they are up to $590 before tax and shipping.
I'll inquire with them direct and see what they can do. I'll look around to.

Ain't that the truth. I'll keep this in mind if I go this route

That is not good.
This is what makes me a little nervous. But also why I was looking for an all aluminum being a welder and all haha.

IIRC, he posted in another thread that his brand new radiator is already leaking, and a repair shop said that the existing weld could not be reasonably repaired, aka Crib Death/DOA

(this comment posted for context, I have a brand new Champion radiator I'm waiting to install, and half-expect it to fail because of course it will)

I recommend getting any kind of warranty offered because all aluminum radiators are prone to leaking, that is the premise for my comment if you do your own research you will see what I mean. It appears to be a gamble if you get a good one or not
