Anyone have any feedback on the Mishimoto radiator for JK Hemi Conversion(AEV)?

Thx

 

Have not seen any Mishimoto talk in quite some time, even for the 3.8/3.6L engines. I don't know if people had such a bad taste in their mouth from earlier issues, or if improvements have been made and there have not been a lot of issues; therefore, not a lot of squawking about em in general.

It seems the general consensus is that Aluminum rads just don't handle the flexy nature of the wrangler frame very well and have a short life before a leak pops up. If it's just a street rig life probably is much better. I'm currently trying a Griffen aluminum in my jeep (just 3.6L) as it was larger than factory and not didn't cost a whole lot more, so guess I'll find how long it takes to fail. I realize that didn't really address your specific question, but I think your concern with that radiator is going to be more about aluminum holding up over time more than the cooling capacity for your hemi. I bet that jeep is fun to drive!

 

Yeah seems like theres mixed reviews and yeah the 6.4 puts a smile on my face everytime i drive it
Thanks for the input.

 

Here is a tip to make a radiator last with / due to the flexing. Take out those 2 long bolts at the top holding the rad in and put some BLUE loctite on them and reinstall with about 1/8" - 3/16" slop before they tighten up. Allows the rad to move independent of the frame it is mounted on and absorbs flex.
JKJB which town are you in?

 

I did this on the last radiator I installed. Those radiators are pretty well situated in there that the 1/8- 3/16" space isn't going to let the radiator fall out.

 

Hey neighbor, im in Edmonton
Thanks for the tip

 

What do you all think about these options:

1). AEV Rad (1 Year warranty)

2). Northern Radiator ( 1 yr or 2 yr warranty)

3). Mishimoto - $920 (lifetime warranty)

 

I have little faith in the Mishimoto, there's just been so little good posted about them through the years. Maybe things have changed, but it's tough once you've got a bad reputation.

 

"Lifetime warranty" sounds good and all, till you're on your 3rd replacement . At some point you get tired of performing the labor and units failing.

 

Woudn't we all just kill for one of those custom brass rad shops that used to be 2 to a block!!

JKJB - I am lucky and was one of the reasons I chose the 5.3 Chev and that was I get to use the stock Jeep rad.
