The OM 622 and OM 626 engines are four-cylinder - diesel engines for Daimler AG and come from a strategic collaboration with Renault-Nissan. The OM 626 was first used in autumn 2014 in two C-Class models (205 series). The basic engine is identical to Renault's R9M engine, and is produced by Renault at its factory in Cléon (France). The engine was then completed at the Mercedes factory in Bremen. Mercedes-specific parts include a start-stop function, auxiliary units (compressor and air conditioning generator), a special double-mass flywheel, a modified engine control unit with additional functions and exhaust after-treatment. The OM 626 and Renault R9M are among the world's first diesel engines to have steel pistons instead of aluminum pistons. Steel pistons with reduced stress piston rings from the supplier Mahle are used. [1] Steel pistons are said to offer advantages in terms of consumption and power compared to aluminum pistons due to lower friction and better thermal behavior.
To change the coolant on the OM 626 engine, you will need to follow these steps: First, ensure that the engine is cool to the touch before you begin work. Locate the coolant drain plug, which is typically located on the bottom of the radiator. If you are unsure where the drain plug is located, consult your owner's manual or a professional mechanic. Place a container under the drain plug to catch the old coolant. Open the drain plug and allow the old coolant to drain into the container. Once all the coolant has drained out, close the drain plug. Fill the engine with distilled water until the coolant overflow tank is full. Start the engine and let it run for about 5-10 minutes, allowing the water to circulate through the engine and flush out any remaining old coolant. Turn off the engine and allow it to cool. Drain the water from the engine using the same process as before. Refill the engine with a 50/50 mix of antifreeze and distilled water. Check your owner's manual for the recommended coolant type and amount. Start the engine and let it run for a few minutes to ensure that the new coolant is circulating properly. Check the coolant level in the overflow tank and add more as necessary. Dispose of the old coolant properly, as it can be hazardous to the environment. It is recommended to consult a professional mechanic if you are unsure about any steps or have never changed the coolant before.
@@MBOwnersClub Thanks! I have changed the coolant in other engines. For example, on a Dacia with similar engine made by renault it had 2 bleeder valves. On om626 (renault engine tweaked by mercedes) I was not sure.

I want to change my coolant. Does anybody know if there are bleeder ports or it just flushes the air by itself?
