Changing oil for GL450 questions
Hello,
I'd like to clarify something for me in regards of changing oil in Mercedes GL450, 2007. According to the WIS instructions, I have to drain oil by removing 2 drain screws. One of them is from engine oil pan and another is from engine oil cooler. Does it sound right to you? Did you do the same? I was thinking to use oil extractor to remove oil. Now, I doubt that using oil extractor will remove the oil from engine oil cooler.
I also confused in choosing some numbers in WIS search for GL450. After I entering Chassis Mode as Car, 164871 GL 450 MATIC, the search also requires to choose between 2 numbers - 273923 or 273943. Does anyone know what these numbers mean? I suppose it is something about engine type but as far as I know the engine is only one kind offered for GL450. I might be wrong.
Thank you in advance!

I just changed the engine oil thru the oil pan screw. I hope I did not leave too much old oil in the oil cooler.
