Default KOYO RADIATOR HELP!

Hello

I just recently got a Koyo Radiator, but I have a problem with it. THe Koyo radiator where you screw on the fan switch is different from the OEM and the fan switch rubber gasket isnt working properly and now I have a leaking problem. How did you solve the fan switch issue for the Koyo radiator?

thanks!

-Jeff

I had the same problem with my Koyo radiator. I had noticed that the stock fan switch O-ring gasket was all smashed also. So the Mugen thermo fan switch with a new O-ring was tighten until it stopped leaking. It worked for me. (The O-ring did deform and appeared lopsided.)

If it didn't stop leaking I was going to pull it out and wrap the threads with teflon tape. But I did not have to go there.

Good luck.
