Hi there, after replacing coolant bottle my car leaking water a t bottom of car only when engine has been running for a while. Tried to bleed system but as soon as fan kicks in water bubbles out of bottle. My heater also blows cold air. Can it be thermostat? Car runs fine

When running the engine to bleed air was the cap on the rad fill hole? It should be so the coolant system builds up the required pressure, may have to repeat this process a couple of times, after engine has cooled,the expansion bottle is the better place to refill the coolant

Turn the heat control to max and remove radiator cap - add coolant as much as possible. Make sure overflow container is filled to correct level - then Start car and run - after the thermostat opens water level may go down some - keep adding coolant till it is totally full. Turn engine off and put radiator cap back on tight.

I'm guessing you can't find it because it's in a separate housing or located under the lower battery tray in the housing (depending on model of engine). Even though this is specific for 1998; I believe it's the same for 1996-1999 Taurus's. I have access to illustrations, but only .gif and/or .bmp extensions were available which would not copy here. If you need these, I will try an extension change to .jpg. Good luck, this should be enough info. It is helpful to include the engine size in question, for future reference...

CAUTION: Do not mix Standard (green) Coolant with Extended Life Coolant (orange). If mixing occurs, drain engine cooling system and refill with originally equipped coolant type. If this contamination occurs the service change interval on Extended Life Coolant will be reduced from 6 years/150,000 miles to 3 years/30,000 miles.
1. WARNING: NEVER REMOVE THE PRESSURE RELIEF CAP UNDER ANY CONDITIONS WHILE THE ENGINE IS OPERATING. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN DAMAGE TO THE COOLING SYSTEM OR ENGINE AND/OR PERSONAL INJURY. TO AVOID HAVING SCALDING HOT COOLANT OR STEAM BLOW OUT OF THE COOLING SYSTEM OR DEGAS BOTTLE, USE EXTREME CARE WHEN REMOVING THE PRESSURE RELIEF CAP FROM A HOT COOLING SYSTEM OR DEGAS BOTTLE. WAIT UNTIL THE ENGINE HAS COOLED, THEN WRAP A THICK CLOTH AROUND THE PRESSURE RELIEF CAP AND TURN IT SLOWLY UNTIL PRESSURE BEGINS TO RELEASE. STEP BACK WHILE THE PRESSURE IS RELEASED FROM THE COOLING SYSTEM. WHEN CERTAIN ALL PRESSURE HAS BEEN RELEASED, PRESS DOWN ON THE PRESSURE CAP (STILL WITH A CLOTH), TURN AND REMOVE PRESSURE RELIEF CAP

By removing the water pump obviously alot of water has drained out therefore you need to prime the air out of the complete water system at the radiator. The coolant leaking out is caused by the hot air rising to escape out the coolant bottle the only exit point.With the engine switched off, alocate a bleed screw on the top or on the side of the radiator and open that screw.Then keep pouring water into the coolant bottle until you see air escaping from the bleed screw.Once the air stops releasing and only water then spurts out, close the bleed screw. The system is now 95% primed. Start the engine and let her idle then open the bleed screw again, if only water spurts out for about 5 seconds then the system is completely primed. If there is still air coming out you can rev the engine a bit to circulate the water faster and then the system will bleed quicker(Not forgetting of course to top up the bottle replacing the lost water from bleeding) as soon as there is only water shooting out the bleeder, close the bleeder and top up the bottle to the maximum mark only. If ever you over top beyond the maximum mark just open the bleed screw to let out some water until it drops to the maximum mark and then close.The system is now fully bled. Problem solved.

could be you have a leak in one of you hose,s

3.2L & 3.5L Engines

1. Before servicing the vehicle, refer to the Precautions section.
2. Drain the cooling system.
   WARNING Do not use pliers to open the plastic drain.
   
3. Remove or disconnect the following:
   NOTE It is good practice to turn the crankshaft until the No. 1 cylinder is at Top Dead Center (TDC) of its compression stroke (firing position).
   Negative battery cable Coolant recovery cap and open the thermostat bleed valve Drive belts Timing belt Water pump mounting bolts, noting the position of the longer bolt Water pump. Discard the O-ring seal.
4. Clean the gasket sealing surfaces, being careful not to scratch the aluminum surfaces.
   
   
   Fig. Water pump bolt locations, make sure to note the position of the longer bolt
   

To install:

1. Install or connect the following:
   WARNING Rotate the pump and check for freedom of movement.
   New O-ring and wet with clean coolant prior to installation. Be sure to keep the new O-ring free of any oil or grease. Water pump with a new O-ring. Torque the water pump-to-engine bolts to 105 inch lbs. (12 Nm). Timing belt Drive belts
2. Fill the cooling system by performing the following procedure:
   1. Close the radiator drain.
      
   2. Open the thermostat bleed valve. Install a 1 / 4 in. (6mm) clear hose about 48 in. (1.2m) long to the end of the bleed valve and the other end into a clean container. The intent is to keep coolant off of the drive belt(s).
   3. Slowly, refill the coolant recovery bottle until a steady stream of coolant flows out of the thermostat bleed valve. Gently squeeze the upper radiator hose until all of the air is removed from the system.
   4. Close the bleed valve and continue to fill the coolant recovery bottle to the proper level. Install the cap on the bottle and remove the hose from the bleed valve.
3. Reconnect the negative battery cable. Start the engine and allow it to reach normal operating temperatures.
4. Check the cooling system for leaks and correct coolant level.
   WARNING Be sure that the thermostat bleed valve is closed once the cooling system has been bled of any trapped air.

Good luck (remember rated this).

Well your on the right track. The container with the coolant knob is where you add your fluid. The fluid being antifreeze. I find that a mixture of 50% antifreeze and 50% water does well. Or you can add it straight and without water. I recommend mixing it. Or you can buy it pre-diluted. On the side of the jug with the coolant knob you'll see a line that says "full cold" and another that says "full hot". You know that if you have not driven your car that day, your engine is considered cold. Its easy.

Its the center-most pulley that the drive belt touches.

3.5L Engine
See Figure 5

1. Disconnect the negative battery cable.

1. Place a drain pan under the radiator. Open the radiator drain located at the lower right side of the radiator. Do NOT use pliers to open the plastic drain.
2. Remove the coolant pressure bottle cap and open the thermostat bleed valve.
3. Remove the timing belt using the recommended procedure. It is good practice to turn the crankshaft until the engine is at TDC No. 1 cylinder, compression stroke (firing position). This aligns all the timing marks and serves as a reference point for all the work that follows.
4. Remove the water pump mounting bolts and pump. Discard the O-ring seal.
5. Clean the gasket sealing surfaces. Do not scratch the aluminum surfaces.

To install:

1. Install a new O-ring and wet with clean coolant. Be sure to keep the new O-ring free of any oil or grease.
2. Install the water pump and O-ring to the engine block.
3. Install the retaining bolts and tighten to 105 inch lbs. (12 Nm).
4. Rotate the pump and check for freedom of movement.
5. Install the timing belt using the recommended procedure. Verify that all valve timing marks align. This is most important. An engine out-of-time will be seriously damaged when first started.
6. Be sure that the radiator drain is closed. Open the thermostat bleed valve. Install a 1 / 4 -inch clear hose about 48 inches long to the end of the bleed valve and the other end into a clean container. The intent is to keep coolant off of the drive belt(s).
7. Slowly refill the coolant pressure bottle until a steady stream of coolant flows out of the thermostat bleed valve. Gently squeeze the upper radiator hose until all of the air is removed from the system.
8. Close the bleed valve and continue to fill up the coolant pressure bottle to the proper level. Install the cap back on the bottle and remove the hose from the bleed valve.
9. Reconnect the negative battery cable. Start the engine and allow to run until normal operating temperature is reached.
10. Check the cooling system for leaks and correct coolant level. Be sure that the thermostat bleed valve is closed once the cooling system has been bled of any trapped air.

This is not a good sign. have your oil changed and see if their is antifreeze in the oil. If so im sorry to say it but you have a head gasket leak. Very common on the F-150's

turn off radio so you wont lose code.disconnect negative battery cable.remove drive belt.get a drain pan to catch coolant.place it under the radiator.then open the radiator drain on the lower right side of radiator.then remove coolant pressure cap and open thermostat bleed valve.BESURE TO PUT COOLANT SOME WHERE SAFE .BECAUSE KIDS AND PETS WILL DRANK IT.know you going to have to move the timing belt.besure to get your engine on TDC AT NUMBER 1 FIRING POSITION.REMOVE THE WATER PUMP BOLTS.AND PUMP.THROW AWAY THE O-RING SEAL.CLEAN GASKET SURFACE DO NOT SCRATCH.INSTALL NEW O-RING DIP IT IN COOLANT.DONT GET DIRT OR GREASE ON IT OR IT WILL LEAK.THEN YOU PUT .PUMP AND O-RING TO THE ENGINE BLOCK.INSTALL THE MOUNTING BOLTS.TORQUE TO 105 INCH POUNDS.THEN YOUR TURN PUMP WITH HANDS MAKE ITS NOT TO TIGHT AND CLEAR. INSTALL THE TIMING BELT LOOK AT TIMING MARKS.GET A HAYNES MANUAL YOU NEED PICTURES TO SEE THE TIMING MARKS.BECAUSE IF TIMING OFF.YOUR ENGINE IS DAMAGED.WHEN YOU GET TIMING RIGHT THEN YOU CLOSE RADIATOR DRAIN.THEN YOU OPEN THERMOSTAT BLEED VALVE.GET A 1/4 INCH CLEAR HOSE ABOUT 48 INCHES LONG.YOU PUT ONE END ON BLEED VALVE AND THE OTHER END IN A EMPTY CONTAINER.TO KEEP COOLANT OFF THE DRIVE BELTS.NOW YOU START FILLING WITH COOLANT BY POUR IT IN THE COOLANT PRESSURE BOTTLE UNTIL A STEADY STREAM OF COOLANT RUN OUT THE THERMOSTAT BLEED VALVE THROUGH THE CLEAR HOSE.GENTLY SQUEEZE TOP RADIATOR HOSE UNTIL AIR OUT OF THE SYSTEM.CLOSE BLEED VALVE REMOVE CLEAR HOSE.FINISH ADDING COOLANT TO COOLANT PRESSURE BOTTLE UNTIL YOU GET TO THE RIGHT LEVEL.PLACE CAP BACK ON COOLANT BOTTLE.RECONNECT NEGATIVE BATTERY.START ENGINE.LET IDLE CHECK FOR LEAKS. IF OVERHEATS YOU STILL HAVE AIR IN SYSTEM.LET IT SET A WHILE ADD MORE COOLANT IF NEEDED DONT DRIVE UNTIL IT STOP OVERHEATING.IF OVERHEAT WHILE IDLING WAIT AWHILE CHECK COOLANT LEVEL.DONT OPEN TOO SOON YOU WILL GET SCALDED.KEEP DOING THIS WHEN IT STOP OVER HEATING AIR IS OUT AND YOU CAN DRIVE IT.
