Hello - Newbie here. Where can I download the Service Schedule for my vehicle? The Service booklet that came with my vehicle only mentions Service A and B but not other stuff like Brake Fluid, Radiator Flush etc. e.g., on this forum, several people have mentioned that Mercedes recommends radiator flush every 2 years or 20k miles. Where is that documented?

Apologize if this is a repeat but I did search for "Service Schedule" but didn't find it.
Thanks.

I use the use the 2016 maintenance guide for my 2019. They are mechanically identical from 2016-2019.

Thanks you so much!!! Pages 10-13 has all the information I need. I have the 2017 Maintenance Guide form MB and it omits these pages. (The 2017 guide is 8 pages shorter than 2016).

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.

Changing the coolant every two years is a pure money grab. I’ve owned Toyota, Lexus, Subaru and Honda and they are all inline with the 10 years/120k miles in the 2016 Service Manual.

Please note the MB language for fluids is "replacement". MB does not use the word "flush". Replacement is very simple: drain and refill. That's all.

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

Thanks. I see that the 2016 Service Manual mentions "Coolant Replacement"

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

@KG300 From which document did you cut and paste the text above?

KG300

From the invoice - please see attached.
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.

Thanks. The word "flush" is from the dealer. MB documents such as the Maintenance Booklet and WIS do not specify flush, they specify replacement. WIS does not call for a pressurized or pumped fluid exchange process, but rather drain and refill.

KG300

Thanks. IDK if the dealer meant a drain/refill or a pressurized fluid exchange. But if MB doesn't require a pressurized fluid exchange, I am not getting one.
A drain and refill sounds fairly straightforward. Do you know the MB OEM Part no. for the coolant/antifreeze?

Best bet is to become familiar with the operating fluids site, formerly known as the Bevo site.

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.

Thanks very much, I've learnt so much today!
