CSF Radiator fitment on 2012+ 370z

CSF Inc.

Hi Guys,

We've had both positive and negative feedback on the fitment. I've personally installed some myself with perfect fitment, and I've seeing others that needed a little work to get installed correctly. We've measured all of our units mouting points on a jig to be the same, but they are all hand welded so +-2-5mm can happen..
We've sold over 250 of these units since they came out, and I would say 75% of them have had zero fitment issues. I pride my company on making sure that we acheive perfect fit with no modifications.. I will look at this again.

I will aim to improve our fitment after reading this post.. Sorry I haven't really been active on the forum as of late due to other applications taking off this year.

As far as the drain plug goes, we're using a harder type of aluminum alloy as well as upgraded washers. I know this was a problem in the past.

We've had a couple warranty issues come up this year with some tube/header leaks, and the proper mounts and washers are critical. As well as making sure that excessive pressure is not run through the system which would cause the life span of the radiator to fail.
Honestly, the warranty rate on this product is higher than any of our other models, and I'm a little puzzled why? They are all made to the same standards, same inspection and testing, at our same factory by the same people. Normal warranty rate is >2%, but this unit is about 3.5-4%

Any feedback on issues or problems with the unit, please PM me or email me at ravidolwani@csfradiators.com..

thanks for the support of a family business, true cooling system manufacture.. I will aim to make our product better

And I had no issues with my CSF's fitment, I did have the trans line slip off the radiator, but that won't be an issue anymore

It's nice that you guys come out here on the forums and talk openly about this stuff, kudos for that Some notes:

Keep in mind a lot of people probably never report the fitment issues. I bought mine through Z1 Motorsports, had to dremel the hell out of the rad core support to fit it, but figured it was normal based on the forums. I suspect the rate of fitment issues is a lot higher than 25%, given how much dremel cutting and grinding I had to do.

I haven't had any issues with my drain or airbleed plugs. The washers appear to just be fat black rubber ones (I guess this is the older washer?) which squish out when you tighten them down, but the threads on the aluminum plugs seem to seal well enough to make it a non-issue (and/or the rubber Just Works for now).

If I had to guess, I'd say the fitment and warranty-rate issues go hand in hand. When you have a sizable chunk of the users cutting on the rad core support for fitment, that creates two warranty-inducing issues: (1) They have to take the rad in and out of the car 10 or more times during one installation for test fitment trying to get the posts to line up and doing more filing and cutting, etc. This probably increases stress and damage potential right off the bat during install. (2) Even when they're done, the fitment probably isn't perfect, it's just as close as they could get it when the posts + mounting bits finally barely fit together. Basically part of your design is now coming from random customer fitment work, so that's a huge source of randomness there.
