I purchased mine in August 2019 and it failed in the same location discussed on here. It was a class 1 leak for maybe three or four weeks. Fluid levels looked fine, but I could smell the coolant and saw the buildup where the fins meet the tank when I inspected it. Today it turned into a class 3 and was losing a little more fluid than I was comfortable with.

It lasted just over 4 years and 23k miles. NA I would see average coolant temps around 220f during the summer in AZ. I put the CSF radiator in at the same time I did the SC, and I don't think I've seen it above 204f during normal operating conditions. Maybe I'm retarded, but I ordered another one despite what I'd consider a short lifespan due to the temp difference.

Mine is still going strong for now. If it has an issue, I will get another one same as you. It's a maintenance item. Now is the time to buy due to Black Friday sales next week.

Saw someone on Facebook who got a shop (or themselves) to attach an OEM condenser to the Koyo radiator.

I swapped from OEM to Koyo this year and it's done well keeping up with my Rotrex SC'd car on track, which has a large intercooler and a short but full width oil cooler in front of the radiator now.

I'm glad you mentioned the condenser! One of the things I forgot to put in my post is they apparently changed from the stock detachable A/C lines to fixed. Kind of annoying for me because I converted the OEM to soft lines because the hard lines won't fit with the intake there.

Radiator problem

be careful of csf radiators guys, another member on myg37 forums have also reported a failure

Vendor Stillen needs to work on their customer service - MyG37

in the past before the triple pass came out i have seen csf radiator leaking issues here on this forum itself. Ravi @ csf stepped in and posted its an extremely rare occurrence etc etc but all i am seeing on the forums are many ppl whose csf radiators have failed and they got 0 support from csf apart from "goto vendor you purchased it from"
its unfortunate, their radiators do help cars run cooler they just need to fix the leaks and fix their customer support and it will be a 100% solid product
