Drain plug

This is a rather simple kind of question. What is the size of the oil drain plug on a 2007 Ford Focus? Help please.(wrench size) metric or otherwise

A crescent wrench is always an option.

Since most of us don’t have Focus cars, and don’t have Ford manuals at hand your best bet is to drop into the nearest Auto Supply store (or Ford parts dept) who will have a long list of drain plugs for sale. Or go to the jiffy lube and ask; someone must know since they take them out all day. The North American Focus cars will likely have a non-metric size, while those for Europe, Mexico and the rest of the world will have metric.

My Nissan, built in Smyrna, Tennessee, has a non-metric plug, while those made in Mexico and elsewhere have metric ones.

Even if we did own that car chances of us knowing the size off the top of our heads is remote. I’ve done about 20 oil changes on my 4runner and I have no idea what size wrench I use. I figured out the size when I bought the truck and now keep a box wrench of that size where I keep my filters and oil.

Thanks for your input…that should get me going in the right direction…

With respect, my friend, I always recommend against the use of crescent wrenches except in an emergency or as a last resort. More hex heads have been rounded off by crescent wrenches than by any other tool known to man.

A set of inexpensive box end wrenches can be bought at the local discoubt tool store for less than $10. I strongly recommend this option.

I also recommend a set of “stubby” wrenches to reinstall the plug with, again about $10. Used judiciously a “stubby” wrench can keep you from overtorquing the plug when you reinstall it.

I Write The Wrench Size In Each Of Our Seven Cars’ Log Books. I Look There Before An Oil Change.

I Respectfully Disagree, also.

Crescent wrenches are for emergencies. The debate should be about 6 pt. vs. 12 pt.

It looks like your drain plug is an M14-1.50. You can take this info and match a drain plug to a wrench at the auto parts store.

What I have done is get a open/box combination metric wrench set where the box end is a ratcheting wrench. This makes it easier for me to change nearly all the drain plugs. I have one drain plug where I cannot use a socket, so the ratcheting wrench allows me to work quicker and easier. I got a 9 or 10 piece set at Costco for about $23.

Yep, I do the same thing. First time out crawl under with the selection of sockets to see which one fits but if its the M14 it is the 14 mm socket. I use a 14 mm and a 15 mm but can never remember which is which so I consult my maintenance book. I also keep the part numbers of common parts like hoses, belts, plugs, filters etc. in there as well as the radio codes, paint codes, purchase price, and so on. Just makes it handy.

I have a little tool kit I use just for oil changed, it had a socket for each of the vehicles I work on most, each painted the color of the car. My 4 way lug wrench has each of the ends painted the same way.

That’s not always true!!!

M14-1.50 describes the THREADS of the bolt, not the bolt hex head size. The threads are 14mm diameter with a thread pitch of 1.5 threads per mm. These bolts purchased raw generally have a hex head of 17mm or 19mm. I’ve seen them as small as 13mm with a large cap on them.

I’ve had to parchase replacement bolts before. The threads match up, but, a lot of times, the factory plug uses a smaller hex head than a general hardware replacement plug. I’ve run into that so many times…

Off the top of my head if I remember correctly. Our fleet: F250 15mm, Miata 19mm, Honda bike 17mm, Toyo 14mm, snowblower 5/8in. Point is it varies a lot. Do you have any wrenches already? If not go to Sears and buy a set. You will never regret it.

Once you figure out the size needed, write it using a magic marker somewhere on the metal inside the engine compartment in front of the radiator. It will always be there as soon as you open the hood.
