Had tap water with a small amount or coolant that was sitting in the truck for a couple of years.now has new water pump, top and bottom hoses,new overflow tank,
Was messing with the 2 carbs to many situation
Just thinking distilled water until all issues taken care of HRL distilled water is in every shelf in stores here in so California even the dollar store
