I measured the fitting coming out of the expansion tank -> the coolant overflow as 8.6mm, which would fit a 5/16"id hose fine (and does snugly, but not tightly) but I seem to remember reading that line should be 1/4" id. Ain't no way I'm getting a 1/4"id line on that fitting unless it's with a heat gun, gallons of lube and a lot of force, which just don't seem smart.
I was taught hoses fit connectors properly when they can't be pulled off, they have to be cut off. Since there's no room to get a clamp on there I'm a bit concerned and thought I'd get the collective's knowledge.
Thoughts? TIA
