W201 Coolant Flush
Hey guys I am going to be replacing my old gold colored coolant in my 190E with the newer blue Mercedes branded coolant.
Is there any special things I need to do or replace when flushing out the older stuff ? Last edited by Wiz190E; 08-24-2021 at 03:54 PM. |

I recommend staying with the original formulation, which is commercially available as Zerex G-05. I don't know anything about the new "blue" coolant, but I know that the HOAT formulation of G-05 offers better corrosion protection for solder than many modern formulation. especially the OAT types.
I'm not sure of the heater core construction on 201s, but if it's soldered copper/brass, stick with G-05. It's easy to change. Open the radiator drain that has a nipple for a hose, and turn the block drain under the exhaust manifold a half to full turn CCW to open it up. it also has a nipple for a hose, so you can do the job without stilling a drop. If the coolant is clean and you can reasonably believe that it's been flushed every five years or so there's no need to do a water flush or use any kind of cooling system cleaner. Duke |

Don't forget to run the heather when doing a flush.
