I have done a many of these on your type of car its a lil more difficult. you will have to locate it and get to it the best you can take a sharp object,preferably a small chizzle and pop a hole in it once you have a hole you can slowly start to pry down ward to try and pop it out once you have it out they offer a universal freeze plug at the autozone's i recommend the universal it'll be alot easier to put in....good luck

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, 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.

Coolant leaking at the top, rear of engine on a 1998 Lincoln Towncar


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.

Coolant leak 1994 voyager 3.3


Could be a freeze plug on the engine block. If you have a block heater installed in one of the freeze plug holes, check it for getting too loose and leaking. Pretty common problem with a block heater that's been in there a long time.

My 95 3.4 camaro is also leaking water. I see it coming out by the oilpan and the torque converter cover hole. It only runs for a bit and the dies. Please help


Are you in the North Eastern part of the US?
Is the engine clock in over 160,000+ miles?

The coolant leak is from the freeze plug(s) and / or head gasket.

The function of the freeze plug is protecting the engine block from cracking in extreme cold temperature. (below freezing point of coolant // -34F)
With the extend cold weather,the freeze plugs will pop out of the engine block.
If you coolant mixture ratio is below 50/50 then the coolant will freeze and expand well above -34F

You can see example for the leaky freeze plugs HERE
==== Freeze plugs are hard to get to and it's labor intensive to replace.
You MUST replace all freeze plugs before you start the engine.
Low or no coolant will over heat the cylinder head and damage the head gasket. ====
A radiator shop will able to do a compression test on the cooling system.
Coolant is toxic to pets! Please do your best to clean up general area and inspect the source of the leak.

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.

Leaking coolant from rear of engine is there a


No, that would probably be a freeze plug on the back of the block if the coolant is coming out between transmission bell housing and engine.
