Does anyone know what size Hex wrench fits the Oil Drain Plug on a 560 SL?

i dont know but i wouldnt be surprised if it is the same as a 617 motor: 13mm. box end.

I believe that it is a 14 MM. Hard to find this hex wrench. The Filler plug has a boss on it, and you can grip it with a pipe wrench.

I think it is 14mm. Most generic parts stores will have this in a 3/8 ratchet bit for a few dollars. Some cars came with the wrench in the tool kit. This is the same size as the rear axle oil fill/drain, and the manual trans drain/fill. Make sure the drain pan has a xtra large capacity or you will have a Exxon Valdez oil spill. They hold somewhere around 9 quarts, and it comes out fast. The oil filter is a 17mm(I think) or 19mm wrench.

falcon6874, try various size 6-point metric sockets until you find the one that fits properly. Then use a 1/2" breaker bar with the socket to loosen the drain plug.

It's a 14mm allen on the 560. A 14mm socket will work if you can find a piece of 14mm hex bar at a hardware store.

Thanks Everyone! Heading down to the local auto parts store today to pick one up.
