Sometimes Redneck engineering works best. Guess I should have said "A Pop bottle" but down here everything is Coke. When we ask,"You want a Coke?" That covers all sodas.
I see a bottle on it's side. I'm thinking it should be upright with the top.... at the top! You did put the hose back on the radiator stub? And if the cap is okay why change it? Anyone want some Coke?
Redneck engineering at it's best. All vehicle overflow containers sit upright. Most have the hose at the bottom or with those fancy type with a hose barb at the top the tube inside really goes to the bottom. Hi tec, shade tree, and rednecks use the same principle. Any old jug will do.
This End Up Are you sure? Pictures don't lie!Unless they are Photoshopped or trick photography is used. Or it involves smoke and mirrors.
