Default DEX-Cool question?

Did I wait to long to change my coolant? I have about 83000 miles on my 98 Z28. When it said 100,000 miles I thought I was doing good to get it changed now but I've heard some people say you should do it pretty often. Anybody with 98 how long did you radiator hoses last or are they still going. I'm getting mine changed today so they don't leave me stranded and also my thermostat. Thanks in advance.

Well I am certainly no expert but my 98Z still has the original DexCool in it with around 45k, and the coolant looks great. Its build date was November of 1997, so I guess it has been in there for 6+ years. I do not see any signs of wear on my hoses, radiator, etc. but those things might not "show" wear anyways. I do plan on swapping all that stuff out soon since it is so old though. The only funny thing is the coolant tank dip stick has some white crusty stuff on it, but the tank and everything else is clean?

Ditto. My dipstick has the same crap on it. Like u said, the coolant still looks great. I plan on draining and flushing it out anyways come spring.
