Coolant Flush or No? - 2012 CLS 550
2012 CLS 550 with less than 80k on it (50 000 miles).
Had a 'low coolant' msg pop up the other day so I'm preparing to top it up but waiting for the dealership to open tomorrow (Monday) so I can use what I'm assuming is factory coolant in there.
Then I thought well maybe I should just do a complete flush and re-fill the entire system with new fluid but am I reading the Service Manual correctly?
MB only suggests a complete flush/replenish necessary at 240 000KM (150 000 miles) or 15 years! If that's really the case then I will forego the flush, save my time, and just top up.
