Ok I just dropped my B18C into my 2k civic and the ports for the radiator hoses are completely different on both the engine and the radiator. So much so that I cant get either hoses (civic or integra) to work. Did anyone have a trick for this or did most of you switch the radiators?

 

With a B18C into a civic with a single core radiator, I would definitely upgrade to a dual core radiator and fan.

 

I'm curious about this as well. I just got my B16 running in my 89 CRX, but I have/had the same problem with the radiator hoses. The ports on the radiator are smaller than those on the engine, so the original CRX hoses are too small for the engine, while the new Integra hoses are too big for the radiator.

As of right now, I've managed to get the old smaller clamps on the new hoses (PITA) and attach those to the radiator. The only problem is that my lower radiator hose is leaking slowly, so I'd like to know a better way to do it.

 

I had the same prob also - I have a B18b and currently am using a stock EG radiator - (plan on putting in double core soon though)

I used the LS lower hose and LS upper hose (fatter than the d-series) - The upper hose I had to snip a little bit shorter so it would make the bend to the engine without kinking.

I bought those worm-drive hose clamps (tighten them with a screwdriver) to use for putting the hoses on the radiator inlet/outlet nipples. I also squeezed on about half a tube of that red, high-temp silicone gasket sealer gunk. I then slipped the LS hoses over the stock radiator and tightened the hose clamps well -

So far, no leaks...

Cheers
