SOURCE: leaking antifreeze

A quick check you can do to help your troubleshooting is to remove the radiator cap then start the vehicle. (Ensure radiator filled so you can see fluid level). Watch the fluid inside the radiator. Initially after you start the vehicle you will get some small air bubbles but they should go away in less then a minute. If after a couple minutes you have bubbles continually coming up or it starts bubbling out of radiator then you can bet on the Head gasket. If you do not get the bubbles it dosen't rule out either one but if they are there as described then you can look at the head gasket.

SOURCE: coolant leak

More than likely it is coming from the intake manifold. You can use a pressure tester that hooks to the radiator and use a flashlight and mirror to get a better look at where it is coming from.

Check out your freeze plugs. They are thin metal cups that press fit into the side of the block. Use a mirror and a light to inspect while the engine is running.

Oil in the radiator


Oil in the radiator might be automatic transmission fluid cooling lines that run into the radiator that are leaking. OR its stuff that is collected over time if the cooling system was never flushed and cleaned out. Its usually antifreeze in OIL not the other way around which means blown head gasket or leaking intake gaskets.

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).

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)

I have a muddy oily substance appearing in the radiator over flow what could this be....it is also clogging the radiator causing it to overheat


You have oil leaking into the antifreeze and if this is happening you also have antifreeze leaking into engine oil could be head gasket or intake manifold gasket or cracked engine block Has the engine over heated resently at any rate antifreeze in the oil is vary bad and will distroy the engines oil ability to lubericate the engine parts

WHERE COOLANT LEAKS OCCUR
Coolant leaks can occur anywhere in the cooling system. Nine out of ten times, coolant leaks are easy to find because the coolant can be seen dripping, spraying, seeping or bubbling from the leaky component. Open the hood and visually inspect the engine and cooling system for any sign of liquid leaking from the engine, radiator or hoses. The color of the coolant may be green, orange or yellow depending on the type of antifreeze in the system. The most common places where coolant may be leaking are:
Water pump -- A bad shaft seal will allow coolant to dribble out of the vent hole just under the water pump pulley shaft. If the water pump is a two-piece unit with a backing plate, the gasket between the housing and back cover may be leaking. The gasket or o-ring that seals the pump to the engine front cover on cover-mounted water pumps can also leak coolant. Look for stains, discoloration or liquid coolant on the outside of the water pump or engine.

Radiator -- Radiators can develop leaks around upper or loser hose connections as a result of vibration. The seams where the core is mated to the end tanks is another place where leaks frequently develop, especially on aluminum radiators with plastic end tanks. On copper/brass radiators, leaks typically occur where the cooling tubes in the core are connected or soldered to the core headers. The core itself is also vulnerable to stone damage. Internal corrosion caused by old coolant that has never been changed can also eat through the metal in the radiator, causing it to leak.

Most cooling systems today are designed to operate at 8 to 14 psi. If the radiator can't hold pressure, your engine will overheat and lose coolant.

Hoses -- Cracks, pinholes or splits in a radiator hose or heater hose will leak coolant. A hose leak will usually send a stream of hot coolant spraying out of the hose. A corroded hose connection or a loose or damaged hose clamp may also allow coolant to leak from the end of a hose. Sometimes the leak may only occur once the hose gets hot and the pinhole or crack opens up.

Freeze plugs -- These are the casting plugs or expansion plugs in the sides of the engine block and/or cylinder head. The flat steel plugs corroded from the inside out, and may develop leaks that are hard to see because of the plug's location behind the exhaust manifold, engine mount or other engine accessories. On V6 and V8 blocks, the plugs are most easily inspected from underneath the vehicle.

Heater Core -- The heater core is located inside the heating ventilation and air conditioning (HVAC) unit under the dash. It is out of sight so you cannot see a leak directly. But if the heater core is leaking (or a hose connection to the heater core is leaking), coolant will be seeping out of the bottom of the HVAC unit and dripping on the floor inside the passenger compartment. Look for stains or wet spots on the bottom of the plastic HVAC case, or on the passenger side floor.

Intake Manifold gasket -- The gasket that seals the intake manifold to the cylinder heads may leak and allow coolant to enter the intake port, crankcase or dribble down the outside of the engine. Some engines such as General Motors 3.1L and 3.4L V6 engines as well as 4.3L, 5.0L and 5.7L V8s are notorious for leaky intake manifold gaskets. The intake manifold gaskets on these engines are plastic and often fail at 50,000 to 80,000 miles. Other troublesome applications include the intake manifold gaskets on Buick 3800 V6 and Ford 4.0L V6 engines.

INTERNAL COOLANT LEAKS
There are the worst kind of coolant leaks for two reasons. One is that they are impossible to see because they are hidden inside the engine. The other is that internal coolant leaks can be very expensive to repair.

Bad head gasket --Internal coolant leaks are most often due to a bad head gasket. The head gasket may leak coolant into a cylinder, or into the crankcase. Coolant leaks into the crankcase dilute the oil and can damage the bearings in your engine. A head gasket leaking coolant into a cylinder can foul the spark plug, and create a lot of white smoke in the exhaust. Adding sealer to the cooling system may plug the leak if it is not too bad, but eventually the head gasket will have to be replaced.

If you suspect a head gasket leak, have the cooling system pressure tested. If it fails to hold pressure, there is an internal leak. A "block tester" can also be used to diagnose a leaky head gasket. This device draws air from the cooling system into a chamber that contains a special blue colored leak detection liquid. Combustion gases will react with the liquid and cause it to change color from blue to green if the head gasket is leaking.

Head gasket failures are often the result of engine overheating (which may have occurred because of a coolant leak elsewhere in the cooling system, a bad thermostat, or an electric cooling fan not working). When the engine overheats, thermal expansion can crush and damage portions of the head gasket. This damaged areas may then start to leak combustion pressure and/or coolant.

Cracked Head or Block -- Internal coolant leaks can also occur if the cylinder head or engine block has a crack in a cooling jacket. A combustion chamber leak in the cylinder head or block will leak coolant into the cylinder. This dilutes the oil on the cylinder walls and can damage the piston and rings. If the coolant contains silicates (conventional green antifreeze), it can also foul the oxygen sensor and catalytic converter. If enough coolant leaks into the cylinder (as when the engine is sitting overnight), it may even hydro-lock the engine and prevent it from cranking when you try to start it. Internal leaks such as these can be diagnosed by pressure testing the cooling system or using a block checker.

A coolant leak into the crankcase is also bad news because it can damage the bearings. Coolant leaking into the crankcase will make the oil level on the dipstick appear to be higher than normal. The oil may also appear frothy, muddy or discolored because of the coolant contamination.

Leaky ATF oil cooler -- Internal coolant leakage can also occur in the automatic transmission fluid oil cooler inside the radiator. On most vehicles with automatic transmissions, ATF is routed through an oil cooler inside the radiator. If the tubing leaks, coolant can enter the transmission lines, contaminate the fluid and ruin the transmission. Red or brown drops of oil in the coolant would be a symptom of such a leak. Because the oil cooler is inside the radiator, the radiator must be replaced to eliminate the problem. The transmission fluid should also be changed.

Antifreeze leaked out bad from the back and bottom of car.


If you have Antifreeze leaking from the back of your vehicle, and your referring to it leaking out of your tail pipe, then i feel for you highly, that could possibly mean warped heads, cracked heads, cracked block, your engine runs and does the natural breath in, Ignite, Breathe out of the Intake and if you have antifreeze in the Intake, then best start looking for a new engine. It would be too much trouble to go thru the current engine you have. If by some chance its not coming out of your tail-pipe, then there is something wrong with your car, And disregard what i have entered.

Leaking antifreeze fluid from under the engine.


might be a freeze plug leaking, or heater hose. there are three freeze plugs on each side of engine and two in back of engine. most likely if any of them are leaking, it will be the one behind the starter on the far right rear of engine block. they have also been known to leak around the front and rear of intake, where intake, head, and block meet.

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.
