Now I know why the right end gets pushed into the front sheet metal cross-member at the top. The top hose is really too long (horizontally) and it is stiff, especially when pressurized, so it pushes the radiator since it can give at the ends. That top hose needs to be .25-.50" shorter!

Stay Puff Marsh Mello Hose.... I would put a new one on the top, that looks deformed epr bronxteck.

Ain't no rule against cutting any hose to whatever length you want either.

Why risk it cheap & easy to replace?
