Hey guys how many are running stock radiator cap on your cooling system? It's getting hot here in FL and I've noticed I've been pushing some coolant in my overflow, was deciding to change the cap... Any recommendations? Will this just put stress on my system?

I have a koyo rad, just seeing whats a good cap to run other than OEM.

Thanks

 

I dunno.... I just use aluminum foil and a rubber band!


JK.... I got a Nismo rad cap, it seems to work well in the AZ heat on days of 120ish.... Yeah, it gets that hot here... Link ---> http://www.conceptzperformance.com/C...4924.255.2.120

 

I found that my OEM cap did not work well with my koyo. Swapping it out for a higher pressure koyo cap resolved my issue.

 

Quality, affordable option:

Thanks! Looks good... Nismo for $55 hell no! lol

 

I just ordered a mishimoto cap for my stock radiator. Along with a mishimoto thermostat. Hey guys, I don't mean to thread steal but is Motul MoCool safe to run through my stock radiator? I don't see why it wouldn't be..
