It didn't on mine. ITR helped me out with the correct cap, maybe he'll chime in...

Correct part number

I was just in the garage and checked - the trd seems to fit perfectly in my koyo radiator... Did you have problems with the physical dimensions, or after the system was under pressure?

The rad is going in next week, so I hope this isn't an issue...

I couldn't find the stocker cap to check it.

Either way, at least I know what to get if I run into a problem later.

It appears I was given the "N" type TRD cap, which is for a JZA70... This should be the cap, right? I just want to make sure it is the correct cap so I don't have any issues under pressure.

stock and trd didn't fit mine. I got the nissan blitz cap (blue) seams to work fine

I'm curious about this too. I have a jza70 (1jz) cap that I ordered that I was planning to run on my 7m radiator. Are they really different?
