If it is a freeze plug it would not have threads. Freeze Plugs are designed to pop out of the block should the water in the block freeze. This could not happen if the plug was threaded. Hope This Helped.
On the lincoln 4.6 lt engine yes you have two freeze plugs in the area of the starter, one exactly above the starter and another above but on the rear side of the block.
It is above where the starter goes cast on the block.if the motor is in you will have to remove the starter to see the #.
Uhh
If you can get to it, yes. But understand that there is probably rust and corrosion elsewhere in the engine and you probably have a few corroded freeze plugs that haven't given out yet. You may need to pull the starter and exhaust manifold to get to the freeze plug, and replacement plugs are available. Once they start to go it probably won't be stopping any time soon. A good anti-freeze with a rust inhibitor is certainly worth the investment if for no other reason than it prevents freeze plug failure.
juice freeze somewhere above 30 degrees and 32 degrees which leaves only 33 in above
You will find the starter located right above oil filter once you remove it. right above converter pipe.
It might happen because of a faulty starter gasket. :)
Removing the starter and exhaust manifold provides much needed access. Getting the old freeze plug out can be difficult. Sometimes you can beat one side of it with a big screwdriver or something and rotate the plug enough to get a pair of channel locks or vise-grips on it and remove it. Put a little shellac compound or similar sealant on the new freeze plug and beat it into the hole with the biggest socket that will fit into the plug. Sometimes a short extension will help.
You must remove the airbox assembly to access the starter from above
You will need to remove the starter to see the casting number. It will be at the right rear of the motor. It's on a flat ridge just above the oil pan. The first letter and number is the year. For example; C9=1969, D9=1979, & E9= 1989
just above the starter on the front of the motor. will have to take the starter off to get to it.
