Antifreeze leak in back of engine

1987 Dodge Ram 150 318 engine. I am leaking a small amount of antifreeze and it seems to be coming from the bell housing. Could this be a rear freeze plug and if so, do you have to pull the engine to replace it?

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.

Why is there antifreezes leaking out of bell housing on a 1999 dodge Cummings diesel engine, is it a freeze plug or a crack in block


there almost certainly will be a freezeplug in that area , but first make completely sure the coolant isn't leaking higher up and looks like from bell housing , get the area steam cleaned and make sure it's not from the head gasket or another freeze plug , 30 minutes spent doing this could save you time and money dropping the gearbox etc , hope this helps

Water leaking beside thermostat houseing


Replace the corroded housing and you will have to replace the rusted welsh plug in the rear of the engine . If it is from inside the bell housing it means gear box out and fly wheel / flex plate off

Water leaking behind moter and i cant see were its coming from


If you have antifreeze leaking from what appears to be coming from the transmission bell housing, the leak is most likely (although possible) not at the rear of the engine.

There COULD be a freeze plug at the back side of the engine between the engine and transmission leaking. However, on the 4.6L engines, it is most commonly caused by either a water pump, heater hose, or intake manifold leaking at the FRONT of the engine.

Leaks in these areas will fill the area between the cylinder heads with coolant, which will run to the back of the engine and out the hole in the cylinder block that is located just above the transmission bell housing. This makes it LOOK like the leak is in the rear.

To verify this condition use a flashlight to look under the intake manifold just past the alternator. Sometimes it is also very helpful to remove the serpentine belt and remove the alternator (very easy to do) to verify that this is the problem.

Take a hard look at the coolant cross-over pipe on the front of the intake manifold assembly. These are notorious for leaking on both sides and VERY LIKELY to be leaking on the driver's side where the thermostat is located.

This problem is so common that an aftermarket company named DORMAN has come up with an aftermarket replacement intake manifold to correct the problem. The DORMAN part number for your vehicle is Part Number: 615-175 It is available at many aftermarket parts suppliers including AutoZone, O'Reilly's, and Advance, for around $230 (USD). (See picture below)

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)

Changed water pump,thermostat, top rad. hose. still leaking leaking antifreeze from what looks like below thermostat housing. have noticed super small hose from water pump to engine. looks hard to replace....


That is called the bypass hose. It could be leaking but I'd take a closer look at the thermostat housing. If you replaced only the thermostat and not the housing, the housing may be leaking. It's a common source of coolant leaks.

I have a 1987 2wd ford f150 and there seems to be rusty water from my rad leaking out of my transmission area???


Hi, there are freeze plugs on the back of the engine block. If one of them has rusted thru, it will leak coolant into the transmission bell housing and out the bottom. You will have to separate the transmission from the engine at least a few inches or more to repair the freeze plug. If you need instructions for doing this, please reply with your engine size and type of transmission.

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.

If you are ABSOLUTLY POSITIVE this is where the Coolant is coming from the ONLY Sorce is Freeze plugs ,There are Usualy 2 Behind the Flywheel.
