Clean radiator, cool engine, coolant PH, flow, fans, shrouds.

Very nice and informed responses considering the potential raucousness of my initial post.

I see I was or could be wrong about the proper ph of coolant.

I have read and assumed that slightly acidic was the way to go.

Friggin pre-mix is so expensive as is all antifreeze.

My old Vet neighbor just filled his 58 Fairlane 500 Galaxy with half well water. Has a brand new 3 core radiator and a fairly fresh motor too. I will have to get him some of this no-rosion for a preventative .
