Anti-freeze question
I used the search mode to answer my question, but it did not fully answer my question. So, my question is, I bought my 2000 Vette last October with 27000 miles on it and I don't have any history on it. The Anti-freeze looks dark, However, I don't know if the fluild had ever been change, it had the original air filter which I changed when I did the oil change. Should I stay with the original anti-freeze fluid? Which I understand If yoy don't flush it out well it can create problems. Additionally, I have been told it can eat the rubber up, I question that. Or should I go ahead and use Preston 50/50 or simular product. And how much flushing is required? If someone had a Peak or simular product in it, can I add the GM Anti-freeze without problems? Thanks in advance.

yes ! !
Dex Cool coolant (which was in your car when it left the factory) is bright orange. You need to change your coolant if it isn't bright orange because that means it's either very old or someone put in something else. Dex Cool is made under license by many national vendors and should be available in most parts store. Mix it 50:50 with distilled water.

Dex will not harm your engine. Been using it in all of my cars since I bought my 97 Vette in 97. Several of my cars have gone the 5 year duration spec'd in the owner's manual. One car went through 5 year changes. No cooling system issues due to using the coolant.

If it is a muddy, reddish/brown color, you need to flush the system (until drain water is clear) BEFORE refilling with Dexcool.
To flush add water and run until temp reaches about 200 F. Then drain.

you are suppose replace dex cool coolant orange one every 5 years i as a certified tech i would not recommend a flush because some of they machines they do flushes with are so powerful the sometimes damage waterpumps and gaskets i recommend to take off top hose and bottom hose and flush out with water after you put in a radiator cleaner aditive. and remember you might want to replace your thermostat and your radiator cap as well.

Any one use Delo ELC ? We stopped using the dex-cool in our shop and replaced it with Delo ELC. Delo ELC has no silicates. That's what is in my 01 ls6 now. It's the "red" stuff. We still use the Delo supreme (green) in some engines if they reqire it.

I thought Delo ELC was mainly a heavy duty antifreeze for Diesel engines? It is good for 8 years and 750,000 miles ! Not many people put 750,000 miles on their cars in 8 years !
