I got a motor recently that has a plug in the head where my temp sensor needs to go. It is not a hex plug but is square like a plug in most rearends. Unfortunately it is not 1/4 or 3/8 so I can't use my ratchets. Any suggestions on getting it out?

What size is the hole? (asuming that it's square)

see if you can find a square headed bolt that will fit in the plug. then either double nut it or use a stud remover on the bolt after placing it in the plug.

Im bettin its a half inch...have to borrow or buy a half inch drive rachet or get an 3/8 to 1/2 adapter

CoryM · 03-28-2002, 09:24 PM

Yes those are normally 1/2". Buy,beg or borrow a 1/2 inch drive rachet or breaker bar, Make sure the rachet is as far down as it will go or else you will mangle the plug.
Those are usually pretty tight.

Which head? The sensor goes on the left(driver side) head, mine's there any way. There's a plug on the right side head also, mine has a 3/8 hex head recess in it.

The recess is square and less than my 3/8 and more then my 1/4- I wish it were 1/2 got that covered. They are 305 heads on a 307 I got for free. I have the open hole on the passenger side I could use but I wanted to keep it on the correct side. Thanks

Only thing I can think of is to find a crappy old 3/8 ratchet, and start grinding!

Get one of the sockets, with the allen wrench heads, and you shouldn't have any problems.
