Hey, still working on my swap. I read that the radiator needed for my swap is a 99 Civic SI rad. Will an EK9 rad fit my EK3 B16a swap? I can get a used one for $30. I believe I have that fan failure (off and on) problem which I read so much about because of different size outlets or hose size? . Thanks!

 

fan failure has nothing to do with the radiator. b series hoses are bigger, but you can make a d series radiator work with good hose clamps.

 

Okay well I'll have to check the clamps again but I'm sure they're tight... thanks.

 

Just want to update. I bought a used EK9 radiator from JSHmotors and BWR B-series hoses, installed them today and it fixed my issue.
