Re: water in tail pipe,fan don't come on by it self
Some condensation is normal, but the cooling fan has three sensors. one on the water bottle telling the fluid lvl. one on the thermostat that tells the fan to come on and one on the block to shut it down when it is too hot. test the one on the thermostat.

you can start at any leaks ?is coolant tank have a bad oder in it , fans not coning on , water pump or drive belt slipping, caddy water pumps are not very good at cooling , and last thermostat staying closed, look fore any water out exhaust tail pipe after warm up , good luck ,hope this is some help ,my caddy was worse when it over heated to many times i found water out tail pipe it was a head gasket.
One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
condensation will leak out of it at times, that's normal,, now if your talking a lot of water, and the radiator is losing water, you could have a bad head gasket, if you have antifreeze in your radiator,, you would smell it if it was coming out of the tail pipe. also check the dip stick to see if water is in the oil, and look into the radiator ( with the motor cooled completely ) and see if you have oil droplets in the water, this could also be a intake manifold gasket issue with some vehicles,,
There is a fan sensor in the radiator. If the coolant level uncovers the sensor, the fans won't work properly. Your water loss is caused by the engine burning coolant. Look at the exhaust pipe to see if any water is dripping from the tail pipe with the engine running. Diagnosing the problem can be tricky. It can be a blown head gasket or a crack in a cylinder head or block.
Hopefully not. If your head gasket is gone , you would see an unusualy large amount of steam/smoke comming out of the exhaust. If you fill the tank when the engine is hot , it would not be suprising to find the tank empty after the car has cooled off. The liquid expands as the engine heats up. Hopefully the problem rectify's itself. If you bought it from a car lot , go back to them. If you bought it privately , it's your problem now. It is possible that there is a thermostat issue and the coolant is boiling away. Most modern cars do put quite a bit of moisture out the tailpipe.
different things could possibly cause these problems, you could have a blown head gasket, causing the white smoke to come out of the tail pipe, it might not be blown enough to lose a lot of coolant [ anti freeze ], but just enough to have some to go into the combustion area to be transferred thrrough the exhaust sytem. you also mentioned running rich, is the air filter in your car in good condition, if not replace it, dirty air filters can cause the engine to not perform it's best. if you find out that it is not the head gasket, check your transmission fluid to make sure it is not doing away with any, i have seen some cooling sysytems fail, when the transmission cooling lines hooked up to the radiator had allowed fluid to get into the coolant, check your coolant to make sure you don't see any oil spots.
Never seen oil come from tail pipe (unless a piston has a broken ring or a hole burned in it.) Cooling sensor tells the computer the engine temp and the computer turns the fan on through the fan relay. Very important for it to work. A blown head gasket will make the engine overheat, can cause white smoke from tailpipe, coolant loss and extremely rough running. Also can cause coolant in engine oil or oil in radiator. What you may be seeing may be water mixed with carbon from the inside of the pipe. Excessive water coming form pipe is also a head gasket symptom. A compression test or cylinder leakdown test or a radiator hydrocarbon test will tell you if gasket has failed.
some water from the tail pipe is normal but if the car is running bad then it is possible the head gasket is blown. on the escorts that i have owned i have found that the main relay is usually burned and needs to be replaced. it is possible that the fan is dragging and burning this relay up if this relay is good then you may be better off taking it to the electrical shop.
