Alright I have an ek with a gsr swap in it. When the the swap was done last year they left my d series radiator and ac. Initially everything was fine but I'm leaking radiator fluid everywhere...headers and the block are stained by it and I'm sick of looking at pooled coolant. What size hose should I use to mount it properly. I don't know if it is a d series hose and too small or a b series hose and too big.

 

There's two ways around this. Use the B series hose and just clamp it down (what most do), or go buy an aftermarket radiator (pay attention to hose size) or a Del Sol VTEC radiator and it will have a larger fitting for the hose.

 

thanks thats what I was thinking ...does anyone know the size ?
