2017 GLC300 Service Schedule
Apologize if this is a repeat but I did search for "Service Schedule" but didn't find it.
Thanks.
I recently had Service A performed and the Advisor said that Mercedes recommends a coolant flush every 2 yrs/20k miles. The guide says on p.13 that a coolant flush is needed every 120k miles. My vehicle has been driven only 18k miles and the coolant level is fine.

There is no flush in the MB vernacular, nor in their service facilities.

But my Service A receipt mentions "Coolant Flush". Wondering what they meant.

I declined because I either get my services done elsewhere (tire rotation) or felt weren't needed (alignment). I did get a brake flush 2 years' ago and will be doing it again shortly. I wasn't really sure about the coolant flush but declined because I wanted to research.

A drain and refill sounds fairly straightforward. Do you know the MB OEM Part no. for the coolant/antifreeze?

Look up M274 and X253. A Zerex branded product will probably work but confirm the specification number, aka "the color". MB changes fluid specs and fluid colors from time to time and it's best not to assume.
