would that fit in the Koyo radiator ???

help is apprciaited

 

the OEM plug should fit. the OEM radiators are Koyo also so i don't see why they would change the thread size.

 

you'll need an fd drain plug. the fc one won't fit. I've bought them at both advance and o'riellys.

 

10mm X 1.25 is the S4 size

 

Both of my N/A's say "Calsonic N350" not Koyo.. ?

 

a very select few didn't have koyos, the majority came with koyo radiators from the factory.

 

My last 2 sevens had the same Calsonic ones....... I'm not sure they are as rare as you think they are. But.... 7000+ > 200+

 

or maybe i was thinking the Calsonic was actually a Koyo, i'll have to pay more attention to the radiator labels. i do know that some series came with an OEM koyo radiator though.

 

All of the ones I'm thinking were 1991's. So.. maybe its 91's.... 91 was, after all, the WEIRD year.
