What ratio of Coolant to use for H/E and pump install this weekend?
Thanks,
Todd
Can someone confirm that the Mercedes coolant is NOT pre-mixed to 50/50? I'm almost certain it is not but, would like to verify.
Thanks,
Todd
a strong suggestion. buy a prestone rad flush and before you change anything do a radiator flush. then refill with distiiled only and flush again. you will be astounded at the crud that comes out.
i went thru 10 gallons of distilled water when i flushed mine and refilled. worth every penny

The MB coolant is in fact blue/dark green, the coolant must remain in the cooling system for the specified interval. There is a silica pack in the coolant tank that maintains proper additive levels for the life of the coolant. MB uses "HOAT" coolants and have absolutely nothing in common with the "change the coolant every year" types (IAT/OAT) that went away with the Jurasic period of automotive technology
I strongly suggest NOT opening the system or adding anything to the system. If your engine tells you that the coolant level is low then add ONLY distilled water and always consult the owners manual.
Coolant changes are performed every 140,000 miles and not any sooner. When the coolant is new it reacts with the engines metals forming a protective layer and achieving a balance in Ph. Adding coolant or changing it early throws off the balance and can cause increased corrosion due to the change in initial Ph of new coolant.
So drain what you can in to a clean pan and use it again, after that to "make up" shortage add 50/50 mix with distilled water, bleed the inter-cooler (a must do) and you are on the way.
Many have split their system, it is easy to do and as I recall a VW or BMW (rounded cylinder) header tank fits nicely on the radiator support.
