Still running original with 60K and Six years on it now. Should it be changed and if so, any idea what a dealer charges?
I have been going by this for my 2018, and nowhere does it mention a coolant change. It might be more important to do the diff, and the transfer case if it's a 4matic.

There is no other page.The MB maintenance schedule for my '14 E350 calls to replace coolant at 150k miles / 15 years. Could it be that you need to look at the next page of your maintenance schedule, to see where coolant replacement is called out?
Not exactly. There is such a thing as additive depletion, which ultimately determines the effectiveness of the coolant to do its job, namely, prevent corrosion. Now if that issue were to be addressed somehow, we're into a whole different scenario.So if a tester says it's good...no need to change it?
There are test strips that show if the corrosion add pack is still good. But they are a little expensive. For the average car, it is less expensive to just replace the coolant per the maintenance schedule.Not exactly.

Inquiring minds want to know.
That's correct. My 15 ML has a semi-solid bar of additive that slowly dissolves over time to get that length of service. Probably why they say to replace the resevoir.I also ran across a post in an MB Blog that said that there is an "additive pack" in the coolant reservoir of E class sedans ( and other models no doubt) after a certain year.
It went on to say that if you change coolant, you need to replace the reservoir also.
NOW, I know that sounds like BS, but if someone would like to verify that as fact, I would be most appreciative.
Really what?Really?
I thought your post meant that the coolant should be changed. Apparently not.Really what?
I have a fleet of old MB vehicles that have mostly original cooling systems and hoses. The coolant chemistries and maintenance processes seem to have passed the test of time.
