I have antifreeze coolant leaking from the rear of my engine and want to gain excess to my rear freeze plugs. Do I pull my transmission to change the rear freeze plugs on the 1989 crown Victoria?

    Yes the tranny needs to be removed for rear freeze plugs to be accessed. These rear freeze plugs usually do not leak as they are protected from rust etc by the transmission. Look for a leaky cylinder head gasket or intake manifold gasket at the rear of the motor making it look like a freeze plug leak

You will need to pull engine or trans for access, food for thought if 1 freeze plug has failed the likelyhood of others failing is pretty high if your keeping the car you might think about pulling motor and replacing all of them and cleaning black death from block at same time

Yes, you have to pull the transmission. But look it over closely. Most likely the coolant is coming from somewhere else. I have never seen or replaced a bad freeze plug back there. Water can't get to them to rust them out from the outside in. Only if you use water only to cool the engine. Heater hoses and the intake manifold gaskets can cause a leak in this area.

SOURCE: antifreeze leak in back of engine

Sounds like your right rear freeze plugs are probably leaking .. but first you need to make sure its not coming from up around the rear of the intake before pulling the transmission . this would be the best way to fix this problem .. thanks jerry holler if you need more.

SOURCE: I have a pretty bad water leak behind the engine

Well, yes, the leak that you describe could from any of those areas, but not likely the heater core. Heater core leaks totally fog out windshield...

More likely causes are cracked coolant hoses, take a mirror and look around. If you do not find the leak, you need to add pressure, it should show up...

Where is the freeze plug on a 1996 mercury villager


Freeze plugs run along the side of the engine block. There are some also between the rear of the engine and where the transmission mounts that you can't see when there connected. Some can be difficult to change depending on which ones are leaking. Sometimes accessories or motor mounts have to be removed to gain access, again depending on which one is leaking.

Where are the freeze plugs located on a 2000 Plymouth breeze


Two on each side of the engine. Two in between the engine and transmission. The others are in the head. Front and back. these leak to muck oil to be freeze plugs. Unless you ran threw winter with no antifreeze. Where is the leak coming from? front or back?

Where are all the freeze plug located on 4.6 w/auto. is there one between the block & transmission


Yes, there are expansion plugs (freeze plugs) on both sides of the engine block and at the rear of the engine block between the engine and transmission. There are also a couple in the ends of the cylinder heads.

With all that said, I would like to add that many times with that engine, the heater tube and connecting hoses can leak and be mistaken for a rear expansion plug leaking. I would definately check this before pulling the transmission out.

There is a tube that runs from the back of the water pump under the intake manifold and out the rear of the engine where it hooks up to the heater hose/heater core. This tube has a small hose connecting it to the back of the water pump. There is also a hole in the back of the engine block that will allow antifreeze from under the intake manifold to leak into the transmission bell housing area. When this tube or hose leaks, it often gets mistaken for a leaking rear expansion plug.

It is very easy to check for this. Remove the serpentine belt and remove the alternator and look under the intake manifold down in the "valley" between the cylinder heads. If there is antifreeze in there, the hose or the tube is leaking. Look at the picture below. Item #3 is the tube and hose assembly I am talking about. Usually, just the hose is leaking. It should be replaced with a short piece of SILICONE heater hose. On some of the vehicles, there are 2 hose clamps. On others, the end of the hose that is attached to the tube has a crimped collar on it. If yours is like this, you can fix it by carefully cutting the crimp collar off and replacing the hose using band clamps. (screw-type)

Also look for antifreeze leaking into this area from the front intake manifold runner. They tend to leak on the front runner near where the thermostat housing is located. These will also leak into the valley area and run out the back of the engine. If the manifold is leaking, chances are it is warped. DORMAN makes a replacement intake manifold kit just for this purpose because it has been so common. It is also very easy to check for this with the alternator removed.
The DORMAN part number for your vehicle is 615-178 (See second picture below)

Was told it is freeze plug and transmission has to come out to fix it.


Commonly known as a frost plug / welch plug, If its the rear one then yes the trans has to come out. make sure the garage fits a brass one as they do not corrode.

COOLANT LEAK


On the back side of your motor... On top there is a aluminum coolant hose that has a nylon fitting in it. Make sure it isnt weaping. It will run down the back of your block. The other thing it may be is a frost plug behind your transmission bell housing. This would require pulling the transmission to replace the plug, Check the hose first. Good luck

Coolant leak from rear of engine in bellhouseing area


Sounds like you have a freeze plug that has rusted out. And it is located in side the bell housing behind the flywheel. You will need to remove the transmission and the flywheel to gain access to the freeze plugs. There are two of them at the rear of the engine above the center line of the crankshaft. One to the left and one to the right.
