Re: How often do you change your anti-freeze, brake...
Tell you what, I have never had a problem with Dexcool. I have a '96 Olds with 120,000 and a Chevy with 115,000. Changed the coolant a few times at most. They never run hot, they especially don't run like the complaints that I read about after Googling. I suspect that the main problem is coming from air in the system or a radiator cap that is allowing the pressure to drop thus enabling the water to boil at a lower temperature. GM's are synonymous for faulty intake gaskets. If the pressure drops the car will run hot. My 2 cents.

Re: How often do you change your anti-freeze, brake...
Doesn't it seem like it would be a good idea to change the Dexcool after 3-4 years or would the fact that the car has very low milage make it a waste of time? Two of my 02s have less than 4k on them.

Re: How often do you change your anti-freeze, brake...
It's defiantly a good idea to change the Dexcool at say 30k increments. I think for you to change it at 4k is a waste of time and money. I don't specifically know the exact numbers on time but mileage defiantly.

Re: How often do you change your anti-freeze, brake...
How long will it last?
Uncontaminated, the engine manufacturers instruct that it may be kept in service for 5 years or 150,000 miles in cars. In trucks, Caterpillar and GM currently recommend that the nitrited version of the coolant be run 300,000 miles or 2 years, re-inhibited with a nitrite-tolyltriazole "extender", and run to a total of 600,000 miles. Use distilled water. P.S. I meant "definitely" not "defiantly"

Is this re-inhibiter available at parts stores or just the dealer? I'm in the mood for a little re-inhibiting today!

Re: How often do you change your anti-freeze, brake...
No idea. I'd say at that point it's time to change.
