I have a D15B7. 95 Civic DX. I was curious to where this coolant hose goes too, if I need to T it off, or if I am missing something. The hose coming up is the water pipe return. The outlet on the bottom of the throttle body usually returns to the water pipe. Now that I have the JR, I have a outlet/inlet for coolant that is near the bottom of the picture. I am wondering how I set up these hoses. Any information is much appreciated.




Outlet on the top, outlet/inlet for SC on bottom left. Hose sticking up on goes is the water pipe return





Just a question to make sure I have it right. The water pipe goes to the fitting closes to that middle bolt, then the a hose goes from here to the bottom of the tb to go to the water pipe return. Can anyone let me know if this is correct?

The coolant "loop" that you are dealing with goes like this: engine to IACV in, IACV out to T/B in, T/B out back to cylinder head/thermostat housing. So your job is to assess your engine and see if you have an EVEN or an ODD number of 5/16" barbs for the circuit. If you have an ODD number, you will remove the barb fitting from the JRSC intake manifold that is at the bottom of your photo above and plug the hole with a 1/8" pipe plug... leaving an even number of barbs for proper routing. Two fittings means you will route as I described, four fittings require a straight hose between the remaining two besides the IACV/T/B loop.

So I do have an odd number. it goes IAVC In/Out, TB In/Out and the one on the head. You said I have to plug the barb on the super charger. How would that work? I mean I know how to plug it, but below that there is a bigger hose that goes to the supercharger that supplies coolant. Where is it supposed to exit?

Thanks!

I think I understand it. Thanks so much for the help!

The larger 5/8" bypass hose barb below the smaller one you have pictured above should loop to a similar sized fitting on the thermostat housing just below it. You removed this hose from your stock intake manifold... put the hose back on the same fitting found on the JRSC manifold.
