Re: Water in radiator rusty looking
 

FYI, the waterless coolant is basically RV anti-feeze. it will not cool unless you used a 20 lb or higher rad. cap. most rads. will not take that kind of pressure. I use that RV AF in my solar hot water system. believe me, it absorbs a lot of heat. but getting rid of the heat using the RV AF is not easy

Hmmm, that's not the info I got from Evans. They say it should build very little if any pressure because it doesn't contain water.

I like to keep a couple gallons of antifreeze in the system.

If you Leak your COUPLE of gallons of antifreeze on the starting line in D 3, you WONT be receiving any XMAS cards from MR. BOOSHELL......

Re: Water in radiator rusty looking
 

Washer fluid, like some RV antifreeze, contains alcohol. Not good for the rubber seals in the cooling system.

been using coolant for years with no concerns but don't forget about Evans Coolant they also post contingency

We used a Prestone product with pure tap water that was a rust inhibitor and water pump lubricant that worked pretty good. Haven't been able to find it as of late, Prestone may have quit making it. All cooling systems believe it or not will have a small amount of electricity running through it so, you have a small amount of electrolysis taking place feeding on the engine block and causing the water to rust up. We have been using the Red Line product, Water Wetter as of late. It seems to work pretty well.
