The rad cap on my mishimoto has turned to **** I think. After a spirited drive to work I see drops and puddles of antifreeze on the radiator and the radiator support.

Summit racing has a moroso and mr gasket for 10 bucks, and 949racing has a Koyorad cap for 20.

What do you guys use for replacement caps?

 

I'm looking for a cap too. I second the question.

 

I got one from a black car.


On second thought it might have been a hispanic car.

 

the $3 13psi ones from autozone.

 

I think the one I got was a 1.1 bar from a millenia I believe....

Dave,

 

The autoparts store caps NEVER seem to work right. The metal is too thin and deforms, letting the coolant seep around it.

 

I run a 15psi cap from Oreilly.

 

Ebay racing type R drift 1.1 bar radiator cap. Seems to function.

 

FM 16psi or Stant 22-24psi.

 

Hows the quality of the FM cap?

 

Cheap autozone one here.

 

I have the one that came with the mishimoto and it seems to work. I looked up the part number to the high pressure stant cap once so I could order it at autozone, but I can't remember it

 

Mine sounded like a coffee pot after driving on hot days, replaced with an el-cheapo from oreillys and it hasn't had a problem since.

 

I ended up getting a 16psi Stant from work. I like my discounts!

 

I suggest the one that isn't Stant.

I haven't had good luck with Stants.

 

I think I paid $3 at NAPA

 

Thanks for all the suggestions guys. Much appreciated.
