How to change coolant on 2013 gl450?
I've removed the old coolant via the petcock, replaced the water pump and all the turbo coolant lines (thanks mercedes for making these plastic and breaking so easily) and need to add new coolant back in. Do I just pour coolant back into the reservoir tank, put the cap on and run the car with the heater on or is there an additional step? Do I need to bleed the air? Thanks in advance.
