I have a 1991 ford lincoln towncar and the freeze plug is leaking but its behind the block. How is the best way to replace it instead of dropping the transmission? please a good response is needed. Thank You and happy motoring

not that i have found. Ford has this habit of changing the bolt hole patterns every year on their parts

Yes, that is a possibility. I have a 4-liter V-6 in my 1993 Ford and it had two freeze plugs that had rusted and were leaking. It was easy enough to replace them because they were on the side of the block but I learned there are two freeze plugs hidden under the transmission bell housing. It they are leaking, antifreeze would be dripping off the back of the engine.

Freeze plugs should not cause oil leaks as they are a safety device for the water jacket.

According to Haynes Manual, for a 4.6 OHC motor, the Freeze plugs are located about 3-4 inches below the cylinder head, under the exhaust manifold. The back plug is 5-6 inches in front of the bell housing on the block. They are pictured on page 2C-21 of the Manual in section 15 Engine Block Cleaning..

If you are in the cold freeze region then it can be FREEZE PLUGS or head gasket,

Freeze plugs prevent the coolant from cracking the block.

The only fix is to replace the freeze plugs.

Could have cracked the block .

YOU WILL HAVE TO DRAIN THE COOLANT FROM THE VEHICLE, THEN POP OUT FROST PLUGS AND REPLACE THEM WITH NEW ONES AND RESEAL THEM.

Remove the motor mount for another freeze plug is behind it

possible to be a few different things...one is a freeze plug on the engine block the other is a blown headgasket

Well it could be the plug but most likly not as you are facing the engine on teh left side by the fire wall there will be a few coolant hoses check all of them for leaks
