Went to change oil on my 2017 3.5 Ecoboost but was stumped when it came to removing the oil drain plug (see Pic attached). Was expecting to find provision for inserting a 3/8" drive extension but no, found this fin shaped thing sticking out from the yellow plastic drain plug instead. Tried turning it by hand without success, then put a pliers on it but it did not seem to want to turn and I was hesitant to apply much force until I find what I am dealing with. Help???

Not sure but it looks the same as the plug on my 2016 2.7l...it turns off by hand but requires some force to get started as the tabs need to get out the "locked" in position.

Use the fingers on your other hand to gently pry the far part of the yellow tabs apart while the other turns it. It's the exact opposite of pressing in on the sides of an aspirin bottle and the plastic is thicker. Turn counter clockwise of course.

Turn it

next time you are at dealer grab you couple extra O rings, they can and will break

I have a 2.7 and mine doesn't have the little fin on there. It has the 3/8 square indent where you could stick a 3/8 extension to help get started if it's stuck. Though it looks like you need to pry the tabs out, you really don't. I just give it a quick turn and the tabs just kind of unlock themselves. I know the newer drain plugs now have the fin style instead of the 3/8 square indent. If it's somewhat stuck try to rock it back and forth with your fingers.

Also, I don't know if they sell just the o ring itself for the plug but I got a entire spare plug with o ring for less than $2.50 I think. I reused the original plug and O ring and but until it goes bad, the spare will be a back up. I've changed oil i think 4x already. No problems.

If you are a DIY oil changer, especially if your truck is your only vehicle or you have a distant Ford dealer, I suspect that having a spare plastic drain plug would be a good idea. Or, even if you go the Iffy lube route for oil changes, be aware that such vendors are upselling a drain plug for $9.50 in some locales, even if the drain plug doesn't need replacement (or it mysteriously failed during their work on your vehicle).

FYI - the part number for the drain plug is KX6Z-6730-B. They cost less than $3, so I keep one in the toolbox and one in the glove box.

Wow, I didn't realize the EB had a plastic drain plug. Glad my 5.0 has a regular one.

Composite connecting rods and cranks coming soon??

Yeah, yeah...a little extreme but at the same time it wouldn't surprise me.

That didn't take long.
