2012 E350 Coupe
Coolant questoin
I need to top up my coolant in my 2012 E350 coupe but the process seems pretty confusing and I don't want to mess it up. My manual says to use either MB 325.0 or 326.0. but I don't know whats in my car right now as I recently bought it. It is yellow if that helps. Should I completeley drain the coolant I have and replace it with one of the two recomended coolants or am I able to add one to what I already have. Advice would be greatly appreciated.
Thanks!

If you just acquired the car and it is +10 years old better drain the coolant and replace the fluid. Same thing with all the "long last or forever" fluids like steering and differential fluids.
