Default EK B20/LS swappers, why is my car is still leaking coolant?

ok, very simple to fix. But i'm still leaking coolant from my upper radiator hose at the radiator-connecting end. I got a B20 swap in my 98 civic. I was told to use a 94+ LS upper hose. I also bought the LS oem clamps for it. Hook it on to the block and stock civic radiator, but it's still not a very tight fit. Leaking in drops I tell ya.....does everybody fix this by using those adjustable clamps to tighten it up?

The Integra hose clamps were made for the Integra radiator which has a bigger outlet than the Civic. You need to get a C-Clamp and tighten it down, sometimes even 2. You need to do this for both the upper and lower hoses.

But it looks so much cleaner with the oem clamps. Can i get a civic clamp to tighten it down?

No, they are too small for the Integra hoses.

i had the same problem with mine. just a little bit of fluid would come out at a time but any fluid is enough to be concerned.

suck it up and get the adjustable clamps
