Paul Sloan was going to use the evanscooling system a few years ago but I don't remember the results.

Dear listers,
After reading about 100 sites on the Dexcool orange coolant. I am confused. I checked my records, I installed it in 1996 and have changed it 8 times using distilled water, had no problems with sludging of any kind, the car runs great, never overheats even in hot weather and when I did my timing gear replacement, I had to remove the aluminum cooling pipes and found no build up of any kind on the inside. I have had no leaks from my radiator and the stuff comes out as clear as it goes in.
There seems to be two camps on this issue, the GM cars owners and lawyers suing and the manufacturer(s). The manufactuer(s)including Prestone swear that the Dexcool type coolant is safe for all metals and vehicles and cooling systems, improves water pump life and prevents corrosion. They seem to feel that the problems were with the GM cars or systems which had lots of air in them. Honda and Mercedes is now using a very similar product which is still ethelene gycol but with organic acid additives to lubricate and prevent corrosion just like Dexcool.
The regular green coolants have silcates which like sand can be abrasive to waterpump seals etc., and phosphates and borates to prevent corrosion. The one common concern is switching from orange to green as this could cause some kind of adverse reaction including the formation of some type of solids clogging radiators and causing corrosion.
Although I am confused but it seems since I have been using this stuff for 8 years with no problems that to switch back could lead to problems.
Has anyone heard of Evans coolant
http://www.evanscooling.com/index2.html
which is a Propylene glycol which is non toxic (they say it is used as a food additive) and 100% waterless compound that is great for cars that overheat and for racing. Has anyone used this stuff or know of anyone?
Also am I the only guy using the Dexcool in their Ferrari? If you are please respond as I feel like the odd man out....

In several vehicles which I know of, have had only the orange stuff (since new) it's been about as corrosive as battery acid. This is NOT replacing it yearly - after 5 years had to replace both cores and pump (in each vehicle), immediately replaced the orange with green and back to changing it out every other year. Not sure how it would be if you changed the orange yearly, but at that point what are you gaining?
My F tech said use any one I wanted so long as it's green.
Less than $0.02 worth

I have been using it for about 6 years with distilled water. I change it every year have not noticed anything at all. As a matter of fact the aluminum coolant pipes look very clean on the inside and the stuff comes out very clear. I switched to it because sevral Ferrari mechanics had told me that the silicates in the green anti-freeze have a abrasive effect over time and have seen some castings such as water pump housings with holes in them because of this.
I am at a loss what to use, maybe the mercedes stuff???? |
