I have had DexCool in my vehicles since new. I do one thing that some don't, and that's keep my puke tank (overflow) tank 1/2 full at all times AND replace my radiator cap every year.

I have read, studied, and even sent in a Dexcool sample to a lab for analysis....

One vehicle has 160K on it and zero problems. Flushed once at 110K and will do again soon.

second vehicle is new with 20K and system remains clean.....

Secret: Don't let air into your system, hence keep the puke tank with coolant in it and periodically change you cap and you shouldn't have any problems....

The whole theme of this may be valid if you plan to run one filled stytem for 150,000 miles for some stupid reason. Douching out your system every two years and putting ANY kind of coolant in isn't going to break any of us cheapasses and is the best maintenence possible. Do that and no one will have a problem.

I flushed and went with green cause my cooling system was
a mess when I bought it and needed to be messed with alot.
If I could be sure it wouldn't be exposed, I would have kept
the DexCool.

My 2001 Blazer is the first car I owned with Dexcool. It presently has 36,XXX miles on it. I haven't had to add coolant once and it still has the original radiator cap which has never been opened. I plan on doing a flush this summer and refilling with Dexcool. I'll probably change the cap to be safe but wonder if it's really necessary if it looks clean and tight. It obviously is working fine and has not leaked coolant or allowed air to be drawn into the system.

I see your point, but wouldn't it be worth the extra few dollars to replace it and have the peace of mind in knowing you did preventative maintenance before the part had the chance to fail? It's kind of like an insurance policy to ward off premature failure of the part. It's like the thermostat. You wouldn't believe how many people I see flush and refill their systems and do not put in a new thermostat. Some say they don't want to spend any more money than they have to, while some others say that it's still working fine. What's there to say the thermostat won't fail tomorrow, or next week?
