Lower Radiator Hose - 440 Swap

KOZ45 said
I installed the Gates hose last week and refilled the radiator last night

Saw a coolant spot on some cardboard overnight ......like no more than a dollar coin size drip circle

Appears there's a very very slow drip at the radiator end.......the clamp is tight

Any tips or tricks?

Sometimes there is a little garbage on the radiator tube that prevents 100% seal of the hose. I would drain the radiator and pull the hose and use some fine sandpaper to shine up the radiator tube, then reinstall the hose and try again.
