2001 chrysler sebring leaking water beneath thermostat housing through a factory hole , I changed thermostat and gasket no change

Hello,
Water pumps have a built in "weep" hole. This is a spot that is built into the water pump that signals the car owner when the water pump's internal seals have failed. When the water pump is leaking from this hole it is time for replacement.
Good Luck!

you would only have water in the oil if there was a a leak in the head gasket or water jacket ports in the engine. if you are losing water,that quickly,then it's either a hose,radiator, or water pump. put a piece of cardboard under veh after youve filled the radiator and veh is cool, that way you can determine the location of leak. if you don't see the location of leak the next day, then odds are it is the water pump and only loses water after engine warms up an pressure forces it out the weep hole in the pump while driving. (note: if you have white smoke coming out of tailpipe then you probably have a blowed head gasket,)

it may be corrosion,that part of the housing may have to be replaced .....cheers

If you follow the top hose out of the radiator back to the engine, you will find the thermostat housing, kinda ball shaped, there are 2 bolts holding it on, get ready for a spill, don't do this hot. Remove the housing, you might be able to leave the hose attached, if not just get it out of the way, pull out the thermostat, put in a new one, no adhesive on the gasket, tighten her up, all set. Hope this helps.

The thermostat is located on the left side (standing from the back of the engine) under the Alternator. First step is to remove the neg bat cable. Try to use a mem-saver as it will save you alot of headache trying to reteach the PCM Remove the Alternator, be careful not to break the electrical connectors. You should be able to see the thermostat housing (looks like half a ball with 2 hoses coming out of it) Drain the coolant, and remove the housing..there are 3 bolts. Note the position of the old thermostat before removal. Install the new thermostat in exactly the same position, with the spring-end facing the engine. Clean any debris and residue from the inside of the housing cover. Put the new gasket on the thermostat and install. After everything is back as it was, re-fill the radiator start the engine and turn your heater on full. Watch for leaks.

You're going to lose some coolant, so have a bucket or other container, and some fresh coolant, ready. Follow the upper radiator hose to the point where it's connected to the engine. The hose is clamped to a metal housing (water inlet) which is bolted to the engine. Remove the bolts (not the hose) and lift the housing to expose the thermostat (may require a little prying with a screwdriver or similar tool). Note how the old thermostat is fitted (which end is up), lift it out of the engine, and then remove all traces of gasket from the housing and the engine. Install the new thermostat and gasket, replace the bolts, add coolant as necessary, and you're done.

If it's leaking at the hose connection make sure the clamp is properly tightened. Remove the hose, clean the area well and retighten. If it's leaking at the gasket you'll need to reove the housing, completely strip the old gasket and apply a new one. Be sure the area is completely clean before putting the new one in place.

you may have a water pump that is starting to fail. Look for the water pump that's driven by the fan belt. look at the housing of the water pump there is a relief hole that they drill in the casting and when the pump begins to fail it will drip out this hole. If that's where your leak is, it's time to change the pump.

depending on what motor you have you may have to lift the intake manifold to remove the tube.the recommende procedure is to replace the intire housing.

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.
