The engine is a B18C, the chassis is 98 Civic Coupe.

Right now I am using the D-series heater hose, but it has a bad kink in it. This is the heater hose that runs from the block and it is under the intake piping. Those who have done the swap will know what I'm talking about.

Which heater hose should I use? Will the Si heater hose work with the B18C and the civic firewall side? Or am I going to have to rig something up to work (oh, great!). Let me know what you've done from your experience.

Note: I am not talking about radiator hoses as I have that issue squared away.

 

you can use a gsr one, they're all in the same location on the firewall.

 

Are you sure? (before I go out and buy them) ahahaha.
