Freeze plugs M103
Now that I have everything open and accessible I think it's a good idea to replace some of the freeze plugs on the psg side (4 total), they are rusty and have traces of coolant underneath them. It looks like a straightforward job, but like to hear some input from people who have done this job. The Mercedes Service Manual tells to use a sealant, is this really necessary? Anything else I have to be aware off?
