Best Engine radiator for Honda S2000

Exact thing happened to me last year. Replaced with a Mishimoto

Just dealt with the same thing with my AP1. The plastic to metal seam fails eventually and causes the leak. I got the Koyorad OE replacement and it was around $100 and took an hour to install.

I went with a Koyo radiator, which is considerably better built than the factory piece, cost less than $300 with new hoses, and took maybe 2 hours, start to finish. Of course, I replaced the coolant at the same time.

Replaced it with mishimoto and haven't looked back. Holds much more coolant that OEM and does a much better job cooling.

just replaced rad and all soft and hardlines with oem hoses and koyo rad. gives me a lot of reassurance in this LA heat. Great upgrade

The Koyo Rad needs it's own custom cap as the OEM won't fit but man does track city daily without issue and fits OEM fans it's a must have.

I would recommend the koyo radiator with stock fans. It’s been 3 years with mine zero issues it’ll run cool in 120 desert.

I've been running a Mishimoto in the racecar for 3 years now with 0 issues and their lifetime warranty including damage during use is hard to beat.

Mine developed a small slow leak out of that nub two weeks after I bought it. Koyo gave me the run around on their warranty, insisting on photos of a destroyed radiator for replacement. I gave up. It’s a shame because it fit awesome and looked great.

my Mishimoto leaked/falied apx 10-11 years after I bought it. and keep the receipt, or your lifetime warranty will not be valid
