Necessary 100k Coolant flush?

So I reached 100k on my 06 Tc. I know Toyota calls for full coolant flush, but I'm still on my original water pump and fluid and its still pink? Never has overheated or got close. So just curious if I can take it to another 20k or something? thanks.

Yes another 20k should not be a problem.
When i flush my coolant at 100k. It was still pink, no rust at all . I could have let it stay in for another 20 to 40 k.

100k and 6 years? I would change rather than waiting another 20k.

an 06? Look at your water pump area, I bet you got pink crusted up coolant? lol; or you could be a lucky one and not have that.

water pump replacement and the V belt while you're at it. Mine was still pink but I've lost fluid due to failing water pump.

i would wait, but do the coolant, pump, hoses, and belt at the same time.

Correct mine is a 06 and its the original pump lol. No leaks or nothing knock on wood.

I just don't see the point in changing it if its not dirty or overheating? Unless its damaging to keep it in there.

I did change the belt out about 1000 miles ago because it was squeaking. Quiet as ever now.

color aside and condition looking aside have you tested the boiling and freezing point of the fluid.

Of course! I work in a bio medical lab, and I have conducted research which has took me numerous hours. Results check out just fine. Please excuse my humor.

I'm at 90,000 on my xB, and when I hit the big 100, I'm going to flush all the fluids.

I do everything on my car myself, so a coolant flush is a walk in the park. I guess I'll give it another month or two and go ahead and do it.
