Hello all-
MY Sol is a 2006 NA with 3800 miles. I'm guessing the Dexcool hasn't been changed. I spoke with a retired GM mechanic who said to change out the "Mississippi mud" to a regular green antifreeze. After doing a search, some here said to replace the Dexcool with new Dexcool. Others said to switch to green/distilled water. Apparently, the Dexcool ,if not thoroughly flushed ,can create the "mud" mentioned earlier. Just wondering what the consensus is. I'm getting her out of hibernation in a few weeks. I've also scheduled for the pinion /flange/etc and vent repair.
Can't wait to see how she handles/sounds with the Probeam,Backbone , Venom brace, new Hankooks and Solo exhaust!
This forum is the best! Glad to see new generation Sol/Sky owners signing on...
Thanks in advance!
John

My experience has been that the "early days" of dexcool had some issues with gasket and seal materials that cause them to deteriorate and cause issues. I believe that has been corrected, but will defer to other members to confirm that beyond my own experience.

My '07 has had (to my knowledge) nothing but dexcool in it, I flushed and replaced when I had a coolant leak (which turned out to be a puking water pump) and has had nothing but dexcool in it since. When I flushed at about 58k miles there was no "mud" or contaminants or discoloration of any kind.

Just be sure not to mix de cool with the green stuff. It does bad thongs

It does bad things.

:agree: They do _not_ play well together!


If there's no apparent leakage ~ leave it alone.

I have flushed out the dexcool and put in the green stuff when swapping the engine out last year. I ran it all summer long with out any problems. I noticed the car ran cooler then when it had dexcool in it.

I did a comparison of antifreezes just recently. It seems that nowadays, color is no indication of content, and that dexcool (or equivalent) is what all manufacturers are going with now. In fact it's difficult NOT to get dexcool-equivalent formulations.
