Working on the cooling system of my '86 GT and have a question about the lower radiator hose. I ordered a new set of hoses from LMR. The lower hose is Motorcraft. Looking inside the hose I don't see a spring to keep the hose from collapsing under suction. Didn't these hoses originally have coil springs in them? Are the new hoses constructed differently so that they don't require springs? Or am I just remembering wrong from back in the '80s?
