What's the deal with the size of Honda's coolant hoses? I took a small straight piece and a relaxed 90 degree elbow into a couple automotive and hardware stores here in Wisconsin and none had identically-sized hose. I found one piece that I can cut both pieces I need out of but it is 3/4" while the original hose seems to be around 7/8". Has the old hose just stretched over time? I can fight it on there but I want to avoid an expensive breakdown on the road.
