I also will add this to the mix. I have a test kit that will test the ph levels and additive concentration in coolants, including the so called long life coolants. I have yet to test one of them that was anywhere near being in good shape that long into the run. |
I'm color blind...it looked normal to me other than the little bit of slippery stuff on the radiator cap. The color is similar to the nice clear red/orange stuff that's in my daughters cavi. I totally agree, the extended life products are not as extended as people are led to believe.
We got the car with almost 100K miles on it, so I really expected it to look a lot worse. It's certainly nothing I would be concerned about, even with as anal as I am.
