Im am putting a JDM b18c into my 94 EX and Im having a problem with the heater core hoses. I had to cut the old ones off when putting the new motor in. Problem is I see A single long hose that runs from under the lower raditor hose around front and connects by the upper radiator hose(on the b18). I believe this is the hose to connect the heater, but am not totally sure. This is about the last thing I have to do befor start up, so if anyone could help me out and maybe post up a few pics I would greatly appreciate it, as Im am getting really excited to get this thing up and running.

this site has great pics to reference... plug in car specs and go to town bro... not sure if this pic will show up... its a "gif" file.... good luck.

 

the heater hose runs from the firewall to the spout on the head (below the vtec solenoid)

 

use a gsr heater core hose from the firewall to the head.

 

For a cheap way out you can use high-heat universal hose from any parts shop(just tell them what you are doing and they will give you the right stuff), making sure it is the right size, and make the hose yourself.. That is what I did, works fine and it has been cold as a biatch in CT this year...
