I own a 1992 plymouth voyager that is leaking water. It has the 3.0 liter motor. Front wheel drive /w air conditioning
It is leaking water between the motor block and the transmission. upon inspection from the top as well as the bottom for leaks in the outlet tube and any other viewable hoses and or water jacket cores (freeze plugs), i need to know before i spend the effort to remove the transmission are there freeze plugs behind the flywheel on this engine ? I know it's not called a flywheel cause it's not a manual tranny, but i'm at a loss for the name of the late the starter turns.This water leak apears under pressure, not when cold. it's is a constant drip, not a stream. it is driveable and i add water every other day. I'm just looking for ideas as to where this water leak could be from. Thanks to all replies

maybe extension or o-ring are leaking.May have to add uv dye and remove air filter housing and air hose going to throttle body to get a better look and use the uv dye and uv light.see attachment.

Upon inspection of the motor from the top as well as beneath while running the only place i have any water leakage or signs of water leakage is the torque converter cover plate at hte bottom of the tranny. So i'm going to remove that plate, and allow the motor to get hot and see if i can detect a leak. the tube that the image refers to i do not have a leak as there are no sighs of water leakage. Now if you have a image of this motor from behind so i can se if it has freeze plugs (i've had to replace 2 already on this motor) then i'll know if i have to remove the transmission to repair htem. if there are none there, how does one get to this tube? removing the water pump, and intake and plenium seems like a bunch of stuff to go thru to simply replace the pipe. Maybe it slide off the tranny side and i can replace it that way ?

I am not sure if any freeze plugs in that area but dont think there is.May be running from underneath the extension tube.Take cover off and take a good look.Wish I could be more help.Let us know what you find out.

ok, in my guide there isn't a procedure to define how to get to this tube. if i remove the intake, and plenium, is this tube viewable? or, does it slide out from the transmission side? the image doesn't really provide the best view of how this tube comes out.
i'm srsly thinking about running the radiator stop leak thru it and forgetting about it. this is getting annoying.
any help is appreciated.

Just a thought: I see the frustration and couldn't find a pic of back of this engine with trans removed to suggest much on that itself.
Perhaps just drain the coolant and pressure test it not more than the cap's rating and the air should be much more obvious by noise perhaps to locate the area or exact spot.
Not to discourage but when I've found an engine that needs ONE freeze/core plug I really doubt all the others and frequently have had to do more than just one. Some can really mean engine removal to properly do them all.
It's been my experience that these only rust out (if that was the trouble) when a vehicle was run long periods of time on water only and a couple managed to rust from outside in but not many over the decades. If there are freeze plugs behind engine and covered by trans I wouldn't think the exposure to external rust would NOT be much there so any and all would be suspect at any time - not a good thing unless you bite the bullet and do them all,

Dear leaker,
Sorry for your problem. I could not find a picture of the back of the engine, I have the factory manual for the 3.0 for a 90 Gr. Voyager. But if I had your problem, I would try KW block seal. I have used it several times, including a leaking freeze plug and several blown head gaskets on friends cars, and it has always worked flawlessly. You need to take out the thermostat (I would replace it, it may be the source of your overheating problem, which, if it did not freeze, is the most likely cause for a plug loosening and leaking, it has happened to me) and replace the antifreeze with water so the block seal will work well. You can save the antifreeze and reuse it. After you fix the leak, and it usually will happen almost immediately, completely clean out the remainder of the block seal and then refill with antifreeze. I woul check the radiator for proper operation, if it needs replacement, replace it. Bad radiators and thermostats are the most common problem that kills older engines, in my experience. You will get many people who will tell you not to use these products, but I have had excellent results, if you do not have the money or time to tear it down, try it. It will only put you out about 8 dollars,but could fix it for good.

As others have noted, there is a metal tube that runs from the water pump, across to the rear end of the engine block, under the plenum. It is very common for this to leak at either end. There are also freeze plugs at the rear of the engine block that are only accessable by removing the trans.
