hoses leaking after radiator change

[Tablespoon]

So, I installed a new radiator on my 97 Legacy.

Afterwards, both the coolant hose, and the transmission coolant line were leaking.

Is there some trick to properly installing hoses that I don't know about? I thought as long as the hose was on, and the clamp was tight, there wouldn't be problems.

old hoses on new things dont always seal the same. I would replace the clamps too

I replaced all the hoses and clamps. I guess I'll just make sure everything is very tight, and keep an eye on it to make sure it isn't leaking any more.

Don't go too tight, you'll break the plastic hose attach point on the radiator or thermostat neck and then you will be very sad.  If you are using worm screw hose clamps tighten them so that they squeeze down into the hose leaving the outer surface of the metal band even with the surface of the rubber.  The more important factor is to seat the hose onto the tube as far as it can go, there is typically a stop point molded into it, and then put the hose clamp so it is between the stop point and the ridge around the tip, but biased to be closer to the ridge.
