So i got up under my 87 740 Turbo Wagon for the first time to change the oil and I was staring this huge oil drain plug in the face i tried a 24mm and that was too big its huge...anyway what size is it so i can go pick up a wremch or socket? Thanks.

 

Just use a crescent wrench.

 

It's a Swedish secret!! If I recall correctly, either a 1" or 1 1/16" wrench will fit.

 

Use 1 inch, NEVER a crescent!

 

a 1" socket ...

 

thanks I happened to find a 1'' Craftsman socket the other day score!

 

Oh God no!!!

Thank you. I have a bucket full of box wrenches and sockets...........but not one D@mn 1"

Guess I leave the car up on jacks and finish the oil change on Monday.

The Search feature was my friend.

 

I used an adjustable crescent wrench, gave me no troubles. Not like it's on tight or anything.

 

An adjustable spanner shouldn't really harm the drain plug, but don't use one if you weren't the last person to change the oil. Every car I've ever bought has had the drain plug on tighter than something really tight. Gas station service centers always do that for some reason. I had to use a breaker bar on the drain plug of my car when I bought it, and being as my breaker bar was a bicycle-seat-post slipped over the end of my socket wrench, it just bent the wrench. It's a cheap wrench, but still.

 

Don't use a socket or a crescent wrench you could strip the oil pan nut...use a 1" LONG(so you can have good leverage) wrench closed side never open side...
