CL550 M278 Coolant
Hi friends, I wondering what color of your coolant and place where I can buy it ?
I'm ordering stuff for maintenance and just realized that my coolant is yellow while all websites selling blue 325.0
Owners manual says that it must be changed after 60k/5yrs (9qt 326.0)
Can't find it online and not sure if it's blue/green/yellow
Thanks

Mercedes dealerships is best bet.
325 is blue while 326 is orange.
You cant tell by the outside of the bottle really. Just 2 digits in the part number are different. Some new guys at the dealers dont even know they have 2 different color coolants. Lol think they switched it up when they went to m278 in the W222, the late model with the separate cooling circuit for the intake intercooler.
