I would like some info on this stuff. The Callaway is running a little hot, but I think its due to too rich on an antifreeze/water mix. I was going to put some redline Water Wetter in when I flush, but I saw this other stuff in the parts store today.

Info? Advice?

 

I've seen this stuff. If you find out how it works let me know, they stock this stuff around here as well.

 

Go withn the WATER WETTER...safe not sorry...!!!!

FYI

tony :cool:

 

One of the best coolants is pure water, but it has a lot of drawbacks. Mostly it cavitates easily and allows corrosion. It also tends to freeze at 32*F.

If you don't care about freezing, you can use pure water with additives to prevent corrosion and cavitation and other ill effects of water. Redline offers Waterwetter, and other manufacturers offer other additives. They are effective for SHORT DURATION in pure water. Cooling will be improved, but the mix must be restored often, or engine corrosion and other preventitive effects will be lost.

Modern antifreeze offers all the additives necessary for protection of the engine, including "wetting" additives, corrosion preventitives, and antifreeze protection. Cooling effectiveness is reduced, however the "brew" is good for quite a while.

Tossing a bottle of "waterwetter" or other additive into a mix of 50/50 AF and water probably near useless as all of these properties are already contained in a decent AF.

The big improvement in cooling is gained by having more pure water in the system, but this is very dangerous to the engine in the long term.

I run 60% distilled/dionised water and 40% green AF and no additives. I flush completely every 5,000 miles. My engine runs very cool. I would not run below 40% AF as I don't believe the protection is adaquate for street use, even with additives. If you are racing and flush every week, this is a different issue, that is why you would use waterwetter or similar additives, not for a daily use car.

Just to be clear, the additives are of limited use when used with anti-freeze as anti-freeze already contains these additives. Pure water cools better than AF/water mix, but pure water has real problems in every day use. Pure water with additives like waterwetter can have improved cooling, but must be flushed quite a bit to offer the same performance and protection as a normal anti-freeze / water mix of 50/50 or at least 40 AF / 60 water.

Good post....thanks Pete

 

The post above is right on. I used the DEI 40 below in my Range Rover and it worked well. I dont think there is much difference in the Red Line or the 40 below. They are both non-toxic and increase surface tension of the water. I have Red Line in the Vette and found it did the same thing as the 40 Below

 

Josh,

Lots of local guys up here use that 40 below, seems to work well for them.
