S54 Coolant block drain

Normally (my experience) the coolant block drain is between cylinders 3 and 4. Not so on the S54 after spending some time looking after an oil change.
I found it under cylinder 2. Without opening it, I'm pretty sure that it is. I purchased the bolt and it matches the one in the following pic. The bolt in the pic also has a gasket ring under it (Bingo).
Looks like I can add the eliminate the mess valve.

Hi Ron,
Did you installed that N-Series Valve on the oil pan in your Coupe? How did it work out? The manufacturer doesn't recommend the N-Series Valve for cars with low ground clearance, but it seems like a good product for my Coupe. I might put one in next time I change the oil.
How did you torque the valve properly? It doesn't look like it will accept a standard socket driver.

Thanks.

There is no need for it on the oil drain in my opinion. The oil drain bolt on S54 is easy to get to and it drains nice and clean. The reason why it's nice on the coolant drain for the block is because when you drain the block, coolant goes all over the place. Onto headers, brakes, trim, lines, everything. Horrendous mess. Way worse than the coolant drain on the radiator or the oil drain bolt. Or on any other drain bolt for that matter.

I would assume you would install the stopcock valve Ron posted with a crowfoot wrench. Then you can get the right torque, if you correct for it.

I had the normal one on my '86 325 and a '84 528 that I used to take care of. I agree with Jon's comments.
I'm going to order a type N, F106N, M14x1.5 Monday to see if it will fit replacing the stock coolant plug. The type N will stick out 1.125 inches more than the stock plug. Will also call the main place for the recommended torque value.

More block pics plus

The following are pics from the M brochure showing the drain plug.
Called Fumoto looking for a a type N one for the radiator drain which is a M10x1.5. They have a prototype M10 but the pitch is 1.25.
Will try to get a blank from them and have it threaded.
Ordered the M14x1.5 one for the block drain from Gomco Sales & Marketing in NY. 1-800-793-0154. Part number F106N $25.60 retail.
There are other distributors listed on the web site depending where you are.

Dragging up an old thread...

Ron, did you ever figure out if the Fumoto valve with nipple had enough clearance?

No. When I did the water temperature sensor there, I didn't.

Looks like it will work. I'll try to do some pics tomorrow.

Thanks, I figured that you hadn't done it due the temperature sensor taking priority.

I'm probably going to try one. Do you still have the valve? Is the nipple threaded into the valve? If it is, do you know the thread on it? It might be handier for me to be able to thread in a Drainzit hose or the like instead of using the nipple. It's been a couple of years since my last coolant drain so I'm not remembering clearly if that's going to be more work than I'd like. At the moment the MINI is occupying my jack and stands (power steering pump replacement and some other underside maintenance) so I can't easily look.

It's too bad Fumoto didn't do an M10x1.5 with nipple, it'd be nice on the radiator.

Looks like it. The inside meets the ball and shell.
Don't know if you can get it back right.

Looks like it will fit on the S54.

Thanks Ron!

Yes, it looks like I wouldn't want to remove the nipple. Not a big deal, I was just curious. I'll order the valve next month when I'm due to change my coolant.

Ron, do you recall where you sourced the M14 1.5 sender adapter?
That looks like a good solid one.

Looks like it's just the OE drain plug drilled and tapped to hold the sensor. You could make that in your sleep
