caravan grant--06--3.8
going to replace hose within the metal tranny cooler line because leak at crimp.
need to pull new rubber hose over the flare in metal line and clamp down.

dodge didn't know size of hose--asked service dept guy and a mechanice and parts desk. they said maybe 5/16 or 3/8. don't want to get under car without proper inside diameter of hose needed.

any preference for clamps--thought worm gear, use two per side.
what size clamp needed?

 

3/8 lines and use Fuel injection hose clamps as they clamp much better that gear clamps. But If all you have are gear clamps they will work
