How to remove radiator petcock on 2010 E250 CGI
Hi all,
I'm losing coolant via radiator petcock, so I'll have to replace it.
Any idea how to remove radiator petcock on 2010 E250 CGI, please? I want to make sure I don't damage something. Photo attached.
Thanks
Milo

This is how it works my 2010 E550. Part looks the same.

Many thanks, Arrie. Will try. Just before I do that, I would like to pressure test the system. What is the maximum pressure I can apply for testing? I expected the radiator cap (overflow tank cap in this case) to indicate the pressure rating, but no such thing. The web mentions 1.4bar (20PSI) and 2.1bar (30PSI) for this cap. Confusing. Would anybody have a correct pressure figure, please?
