Bulging hose
I popped my hood with the engine warm, and noticed a new bulge in my upper radiator hose, right next to the thermostat. I gave it a little squeeze and could feel coolant moving, but it didn't shrink any.
Does this mean my thermostat is obstructed? The engine seems to cool well enough for it being a hot summer day.

Any secret to removing them? I remember an uphill battle with the tensioner hoses that was narrowly won, between 15 years of being clamped in place and the rubber slightly melting to the metal underneath.

dont reuse those junk GM clamps, there more trouble than there worth. and the other hoses should be replaced as long as you have to drain the coolant anyway

Justin.. didn't we let Colin take this off with the hose clamp tool when the motor was pulled to be cammed?
Overall that'* one the easiest of the clamps to get to. And FWIW the coolant flow comes out of the thermostat housing and into the radiator through that hose. The most likely reason for it'* pregancy is you parked next to a Chrysler and it impregnated your Bonnie. Or the years of heat cycles etc.

The hose clamp tool is sent straight from god himself. Also yes that hose came off with the engine and was the radiator done by you? So it should come off of that pretty easy.
