In my 83 monte Carlo sc&I've allways had an aftermarket set of gauges oil water batt.Well what the problem is I use to have the water unit running to the head but when they built the motor they put a plug in the head&used locktite.I've tryd to get it out but it seems to be a little smaller than a half inch I've tryd grinding down a half inch socket to no avail.Any idea to get a tool for this its a plug where the tool would have to go in it(no head)hope I made sense.I'm really wanting to hook it back up but don't wanna break anything.Any help would be greatly appreciated thanx guys!

Take a propane torch and heat it until it gets red, then hit it with lube. The heat will break the loctite. Usually plugs like this have a rachet head as in 3/8 or 1/2 drive, meaning a ratchet with a extension and the extension goes in the slot. make sure the plug doesn`t have paint build up in it making it seem smaller than it is. I can understand wanting to move the sending unit to the head, as you`ll see a big can of worms opened if you ask which is better. I perfer the head because that`s where all the action is plus it reduces the amount of clutter on the intake. Others perfer it in the intake as they feel this is where the coolant will be at it`s hottest since it just came out of the head.

If it's a square plug, a 6- or 12-point socket doesn't fit, you need a square (8-point) socket.

Its just a hair smaller than a 1/2 in.I can't seem to find the right tool.Like I said I've tryd to grind a half in extension down a hair but can't get it just right.

You have a female plug that needs a male socket.
