Block Drain 450SE, Where???
 

Help, I'm stuck in the middle of this and running out of time. I thought the block drain might have been that 19mm bolt in front of the starter but it was not.
Is it the 20something mm bolt next to the oil filter housing?

1974 450SE W116
Thanks

Drain plug location ?
 

Hi Josh, I don't have a W116 but I looked in EPC and it appears it's located on the drivers side, just next to the motor mount, front. High, just below head surface. I hope that was correct. Take a look anyway.

Block drains on my 4.5 look just like 19mm bolts. There is one on each side. Remove the plug and I can almost guarantee nothing will come out. Once the plugs are out take a small screw driver or awl and poke it through the crud build up that is sealing the drain. I promise water will come out once you have the plug of crud cleared.
