I would also do a few checks to find out the reason for the swollening....check & make sure your bottom hose isn't collapsing....Check radiator cap.16psi.... malfunction enough pressure to swell the hose...Maybe just a bad hose?

If it stays like that for more than four hours, seek medical attention!

could pressure be building from a blown head gasket

it's a bad hose..just replace it...I doubt it's a blown head gasket..this hose issue is common on small blocks

and put yer t-stat back in

 

[paynegregory]

so I think I should replace hose, cap and thermostat and see what happen

When there is no pressure in the system does the hose feel really mushy? If so it needs replacing. If it's like a new hose it could be several things. Bad radiator cap, holding too much pressure. Stuck thermostat, stuck closed and not allowing circulation. Bad head gasket, allowing compression to leak into the cooling system. Think simple, sounds like an old hose to me...

Those hoses are braided. If it swells,it's junk!

Yep, bad hose. Take out bad hose; put in good hose.

Good hoses do not swell from to much pressure they blow so it is likely just the hose that is bad
