DexCool Question
Hi all,
My car will be 2 years old soon.
Even though Dexcool says that it is usable for 5 years, I don't trust it.
How often doany of you change your "5 year" Dexcool.

Most that I read was vhicles with age on it.
If proper care I dont think dex cool is bad.
When checking the anti-freeze
you need to check for protetion level as well as ph level with dex cool.
This is a must with any extended life anti freeze. Not just with Dex Cool.
PH is very important of reg. maintance for this type of anti freeze.

Maybe it is true, "once you go green, you can't go back."

RE: DexCool Question
There is a lot of speculation about the Dex-cool, particulairly from the 3100, 3400's that have issues with the lower intake manifold gaskets. Dex cool gets a lot of blame, when I believe its the gaskets itself. I had a 3400 in my old minivan. Some of our freightliners at work have it, without problems.

We have over 175,000mi on my wife's '99 Silverado Z71 Sportside 5.3L. I had the dex-cool replaced at 110,000mi with dex-cool. No problems so far. I will replace it again at 200,000mi. I thought this would be a good test to see how well it held up. I'm happy so far. Not sure what will go in then.
I agree that it's the gaskets not holding up on some engines. Compatibility issues. I'm guessing they still used the same gasket material from pre '97 when they made the switch.
I honestly never expected it to last this long. (KNOCK ON WOOD). Been running Mobil 1 the whole time too. Never done anything to it other than basic maintaince.
