How the heck can you strip the drain plug on a 603's pan? They have very long fine threads, some moron must have used an impact gun or breaker bar on it.

A 13mm open end wrench is all you need.

Before going nuts I would get a new plug and see if it bites. If not your going to have to helicoil it.

Pulling the pan on a 603 is a big messy job, I wouldn't even dream of doing it for a stipped drain plug.

fastlane's got them for $411

Yeah, and you also almost need to pull the motor to get it off.

The 603 is nothing like a 617 underneath. On a 617 yeah its cake just get a new pan and be done with it. A 603 has a big super expensive cast aluminum pan that runs the length of the motor. Mercedes being smart made the drain very long with fine threads to prevent this...

That depends on how fast the oil sucker sucks. If it sucks as fast as you can drain, then the sucker will flush as well or better than draining. Also, at least on my vehicles, the sucker removes a little more oil than draining.
