Thanks Gilly,

I'll follow your advise. I preffer to use the plug because it is the downmost section of the radiator, and I read from others that some saw some black hard particles coming out of there, maybe also on the bottom of the engine plug too.

I have my maintenance up to date per the book at 103K, but living in FL I though coolant was not that important to replace, so this is my first coolant change. I know, I know... but so far I have no temp problems and no coolant loss.

I understand about the dealer's way. I went the other day for alignment and break fluid flush, and they told me that now it is called "break fluid refresh"...mind you...

I don't know what the diffeence is but still I asked them to do it.

Thanks again, I will report if I run into any problems. I'll do it next weekend, and yes I am using MB yellow stuff.

Rene
