[Karl Bebout]

Since Evans has such a high boiling point, there is very little pressure in the cooling system. Easier on the radiator, hoses, and connections. It also lubricates the water pump, and prevents corrosion between aluminum and stainless steel parts. I think that's called "galvanic corrosion".
Its been years since I had to buy Evans but I'm sure I used to pay at least $40/gallon, but I thought it was well worth in when my overheating problems disappeared.
