Re: 2002 chryler sebring is leaking anti freeze
It depends on where the leak is coming from. If the water pump is leaking, it has a hole on the bottom of it. You will see a trail of dried anti freeze coming from the bottom of it, indicating a bad water pump. It's best to dry everything off, crank it up and let it come to operating temp and check for where the leak is coming from. It may just be an old hose or loose clamp.

Yes, your water pump attaches to the front of the engine block. If a leak opens up between the two, coolant goes into the crankcase along with oil. That means water and oil are being circulated through the bearings and cylinders of your engine. Don't drive it in this condition.
Sometimes, not the heater coil...this leak usually smells inside the cabin...can you see anti-freeze build up anywhere? These motors are more prone to a water pump leak (needs replaced, inexpensive and not to difficult) or the intake manifold gasket...more costly about $400. for a mechanic to do...you should see some anti-freeze build up around the intake bolts...this assumes that there is no water in your oil...which is far more costly as this indicates an internal cylinder head leak...Could be just a hose leak...a bad radiator cap...or thermostat housing leak, (maybe a cracked housing? Help me help you...do you see any anti-freeze build up anywhere? Hope this helps.
YEP YOU HAVE LEAK AT THERMOSTAT HOUSING.YOU NEED REMOVE THERMOSTAT HOUSING OUTLET AND CLEAN THE MATING SURFACE THOROUGHLYTHEN APPLY RTV SEALANT IN THE GROOVE OF THE WATER OUT LET HOUSING.INSTALL THERMOSTAT WITH SPRING TOWARD THE ENGINE TORQUE THERMOSTAT OUTLET HOUSING BOLTS 89 INCH LBS.IF STILL LEAKS OUTLET HOUSING COULD HAVE CRACK IN IT CAUSING LEAKING.
It Depends on which engine you have, this is how it goes for both. I use a little RTV with a new ring as well.
THERMOSTAT REPLACEMENT (4.2L ENGINE)
Removal Procedure 1. Remove the necessary coolant from the radiator. 2. Remove the generator. 3. Loosen the outlet hose clamp at the thermostat housing. Remove the outlet hose from the thermostat housing. 4. Remove the thermostat housing bolts. 5. Remove the thermostat housing from the engine block. 6. Clean all of the surfaces of the thermostat housing. 7. Clean the sealing surface of the engine block. Installation Procedure
1. Install the thermostat housing to the engine block. 2. Install the thermostat housing bolts. Tighten: Tighten the bolts to 10 N.m (89 lb in). 3. Lubricate the inner diameter of the radiator hose with engine coolant. 4. Install the outlet hose to the thermostat housing. Secure the hose with the clamp. 5. Install the generator. 6. Fill the cooling system with specified coolant and concentration. Follow the correct cooling systen bleed procedure for your engine. 7. Inspect all sealing surfaces for leaks after starting the engine.
THERMOSTAT REPLACEMENT (5.3L ENGINE)
1. Drain Radiator and remove the radiator outlet hose. 2. Remove the water pump inlet bolts. 3. Remove the water pump inlet and thermostat from the water pump.
Installation Procedure IMPORTANT: The thermostat is not serviceable separately. The water pump inlet and thermostat must be replaced as an assembly.
1. Install the thermostat and thermostat housing to the water pump. 2. Install the thermostat housing bolts.15 N.m 3. Install the radiator outlet hose. 4. Fill the cooling system with specified coolant and concentration. Follow the correct cooling systen bleed procedure for your engine. 5. Inspect all sealing surfaces for leaks after starting the engine.
If it's leaking at the top of the engine down. Look at the top of the engine at the front and you'll see a bleeder valve on top a black housing. These housings like to come apart at the glued seams. If it's leaking at the lower part of the engine towards the front, it could be your water pump leaking. Check your oil and if you see the color of the oil looking like chocolate milk, your water pump needs replaced, the oil will need changing as well. Do a coolant system pressure test and see if your hoses somewhere are leaking. Also check for your surge tank leaking. This is the tank that you put coolant into.
