Waterpump hose it connects at the bottom of the waterpump the tip is a hose but the mid section is pipe and runs back to the radiator i went to the auto parts store and they told me to go to the salvage yard

One runs to the charcoal canister, and the other goes to a port running to a metal tube connected to the intake manifold (I'm not familiar with the Edge, but on the mid-90s Taurus, the intake manifold tube connects near the throttle body, and the connection to the charcoal canister is a fitting near the bottom of the radiator). There should be a decal on the top of the radiator frame showing a diagram of the vacuum hose connections.

Follow the top and bottom radiator hoses. Goes goes to the thermostat in a round about way which is right on the top of engine behind the EGR valve. Bottom hose goes right to the waterpump, easy access from underneath. The temperature sensor is located on drivers side mid engine. Look through drivers tire wheel well, you can see the sensor, brass fitting. A note, the top hose where it's attached to the thermostat is metal....tends to rust out, just get a new one and snake it back through there.

1. Before servicing the vehicle, refer to the precautions section.
2. Drain the cooling system.
3. Remove or disconnect the following:

• Splash shield
• Lower heater hose
• Radiator lower tube bolt
• Radiator upper front tube bolt
• Air cleaner assembly
• Battery and tray
• Water pump belt
• Upper radiator hose
• Engine vent hose
• Transaxle 10 pin connector
• Radiator bypass hose assembly
• Thermostat housing
• A/C compressor brace, if equipped
• Water pump mounting nuts
• Connector hose
• Water pump

To install:

1. Install or connect the following:

• Water pump
• Connector hose
• Water pump mounting nuts and tighten them to 15-22 ft. lbs. (20-30 Nm)
• A/C compressor brace, if equipped, and tighten the nuts to 15-22 ft. lbs. (20-30 Nm)
• Thermostat housing
• Radiator bypass hose assembly
• Transaxle 10 pin connector
• Engine vent hose
• Upper radiator hose
• Water pump belt
• Battery and tray
• Air cleaner assembly
• Radiator upper front tube bolt
• Radiator lower tube bolt
• Lower heater hose
• Splash shield

2. Fill the cooling system.
3. Start the engine and check for leaks.

The water pump is enclosed on the front of the engine. The bottom radiator hose connects to the water pump inlet.
You do not add coolant to the water pump. You add a 50-50 mix of antifreeze and water into the radiator cap opening. Or you can buy the coolant already mixed with water and just pour it into the radiator.

The coolant system uses the water pump to circulate the coolant through the engine and then into the radiator via the upper radiator hose for cooling it off, and it then goes back into the engine through the bottom radiator hose. When the engine is warmed up, the coolant constantly circulates through the engine to radiator and back into the engine.

1) Drain radiator by removing cap, and bottom radiator drain bung or bottom hose.
2) Remove top hose.
3) Disconnect the radiator fan's wiring and any temperature sensor wiring if fitted.
4) Remove radiator retaining clasps
5) Disconnect radiator bottom hose.
6) If fitted with an auto box, then remove automatic gearbox oil pipes (Underside)(you might wat to clasp these so they don't leak oil everywhere)
7) Remove radiator expansion bottle feed pipe from top of radiator.
8) Ease out the radiator. If the radiator fan is getting stuck or caught up, then drop the radiator back down and remove the fan first after disconnecting from the radiator body.
9) With new and old radiator placed side by side on a soft surface, change across any components from the old radiator, which didn't come with the new one. These may or may not include such things as: cap, fan retaining screws or clips, bottom radiator seating rubbers, rubber fan shrouding, temperature sensor, top and bottom rubber hoses.
10) Rebuild by reversing the above instructions. Apply silicone pipe sealant to top and bottom hose locations. Make sure you clean and/or replace any heavily corroded metal pipes which connect to the radiator. (Now is also a good opportunity to replace the thermostat to be on the safe side)

11) Fill system with a fresh 50/50 water/antifreeze mix, flush out and refill expansion bottle. Just before you refill the system, turn the interior heater setting up to maximum heat, but do not start the vehicle.
12) Top radiator up to max. Gently massage the top radiator hose to help eliminate air from the system.
13) Once filled, start the car. Pay attention to the temperature. Keep topping up the radiator as bubbles come around the system and the coolant level drops. At the point no more bubbles appear, close off the radiator with the cap. Allow the engine to reach normal operating temperature. If the weather is cold you may want to hold the engine at around 2,500 revolutions to help build heat faster. Keep it running until the radiator fan kicks in, then let it idle for a couple of minutes.
14) Stop the engine and let it cool.
15) Once cool, open the radiator cap and top up again if level is low.

16) Road-test the vehicle. After returning check again for any leaks.


Running the car for the first few days after radiator replacement, check the radiator level and expansion bottle level every day for the first two or three days. This level may drop slightly as any trapped air pockets are pushed out while running. Also, it is possible that any small leaks may begin after adding fresh anti-freeze to the system. If you begin loosing fluid over these first few days, then re-inspect your work and run a cooling system pressure test.

DRAIN COOLANT SYSTEM.DISCONNECT THE RADIATOR INLET HOSE FROM INLET PIPE. REMOVE THE TIMING BELT FROM THE WATER PUMP PULLEY. REMOVE THE RIGHT SIDE IGNITION COIL.REMOVE THE WATER INLET HOUSING AND THERMOSTAT.REMOVE THE MOUNTING BOLTS AND STUDS. LIFT OUT THE WATER PUMP BY CAREFULLY PRYING BETWEEN THE PUMP AND THE CYLINDER HEAD. REMOVE ALL THE OLD PACKING AND CLEAN THE MOUNTING SURFACES. INSTALL NEW SEAL PACKING TO THE WATER PUMP GROOVE AND A NEW O - RING TO THE WATER BYPASS PIPE.INSTALL THE TIMING BELT AND CONNECT THE INLET HOSE TO THE INLET PIPE.THEN REFILL THE COOLING SYSTEM. RUN THE ENGINE CHECK FOR LEAKS.

If you started the car and checked the hose more then likely it's comeing from the radiator nipple where the hose connects and is running down the hose. I feel you need to have it pressure tested,
Most shop will not charge for this. They put on a presure pump on your radiator cap go's and pump it up to find the leak exact location. Good luck to you,

Hi,
The water pump can be located by following your bottom radiator hose to the engine... it connects to the pump.
The thermostat is done the same way by the top radiator hose. The hose attaches to the small housing for the thermostat (usually on top of the engine).
I hope this helps you. Good luck!

That is the water pump "outlet" tube. It is held on by one screw and it has an o-ring at the end that seals it. You need to replace the o-ring. I also put on some permetrex grey sealant around the o-ring, then stuck it back in.

could be a leak or crack in a radiator hose
could be water pump not working good or leaking
could be radiator leaking
could be thermostat half blocked
