Hello guys, I am in the process of doing the vaccum, fuel and coolant hoses. And I'm kinda stuck on what size is the coolant hose that goes from the vaccum harness to the water pump housing. I tried 5/16" but it was too small, then I tried 5/8" but it seemed to be too big. Any ideas?

The hose in question has red dots...

I think it's 1/2. Autozone or any other place you can get hoses sells a preformed elbow that you can fit on there. You'll have to buy hoseclamps if you don't have any to replace the old ones. I beleive the preformed hose is $6 cut to fit. I wouldn't reccomend trying to bend it cause you may cause it to pinch and kink by doing so.
