'70 440 Block Drain Plugs

[MoparHonda]

I have a '70 GTX 440. What tool is best for taking out the two block drain plugs? The plugs are some weird square peg like thing.

(I have other Chrysler cars and those are all regular 9/16 bolts.)

if they are square find an open end wrench that fits.

Thank you, BeeKeeper. Tried that, it's a 1/4 (if I remember correctly). The problem is that a 1/4 open end wrench is really short, and I can't get enough leverage to move the plug; It's probably rusted in.

I was hoping there was some type of socket or long box wrench for these plugs?

(As you know, as the size of the wrench gets bigger, the length gets longer to provide more leverage.)

There is a type of socket used for those its an 8 point and you should be able to pick one up at sears or a tool supplie house

Thank you, I'll see if I can grab one. Does this socket have a particular name?

1/4" 8 point socket.

Use a 1/4 inch drive socket that you put the square 1/4" hole over your plug and put an appropriate sized allen wrench in the socket hole...................................MO

Got the plugs out, thank you to all who responded.

They are 3/8, not 1/4 as I stated before. I used a 3/8 socket extension and put a crescent wrench on the other end to get the driver side one out. Used the same 3/8 socket extension and put a 16MM six point socket on the end to get the passenger side one out.

Just for those who don't know...

There are sockets made for those square-headed plugs. Sockets are 4-sided at each end, one for the rachet drive, one for the plug head size.

Wouldn't a crescent wrench be long enough to put/get some smash on it?

The problem that usually arises when using open end wrenches on this stuff is there's not enough contact and you end up rounded off the head of the plug. And yes, 4 point sockets are produced and give you the most contact.

And what's a MoparHonda? I remember a guy that went by ToyPar....had a small block in a Toyota pickup and was a pretty quick street truck.

MoparHonda is just the userID I use.

I keep Plymouths and Dodges, I have six, but I have been driving a Honda every day since July 1977.

Put a small block Mopar in it
