Air in radiator hoses - 1999 Lincoln Continental

most likely air in the colant system, an air bubble trapped when water pump was replaced. An eazy way to tell if air is in the coolant system squeze the upper radiator hose, if seems empty or can hear coolant swishing around, then there is air in the coolant system and also coolant level not compmetely topped off.

Top off coolant with Antifreeze Concentrate, NOT WATER. water will boil and evaporate, 50/50 antifreeze mix is good but if you dont know how much water has allready been added to the coolant system then straight shots of Antifreeze is recommended when toppong off coolant level.

Remove Air and Top Off Coolant

•While Engine is cool
•Remove radiator cap
•Slowly fill to the rim with Antifreeze, while at the same time squeezing the upper radiator hose to swoosh around coolant, try to get as full as you can.
•Replace Radiator Cap
•Start engine and switch air fan on high
•Remove radiator cap
•Squeez upper radiator hose and add more Antifreeze as Nessesary
•Notice preasure on the coolant hose, while adding antifreeze Concentrate preasure on the hose will stiffin up,
When coolant is full turn off the motor.

Depends whether a problem is suspected or whether the radiator is definitely the cause of the trouble.

Flushing a radiator requires it to be no worse than moderately blocked because without reasonable water flow flushing is doomed to failure and even then it is nearly impossible to clean the interior of a radiator without taking it apart and rodding out the tubes or using either an acidic or a caustic additive.

Flushing the old coolant out and a small percentage of sludge is as much as can be accomplished unless an additive is used and even then with variable success. I do this by disconnecting the heater outlet hose and fitting the (turned on) garden hose to it and then running the engine until the water runs clear. Once this is done I transfer the garden hose to the top of the radiator (top hose disconnected and plugged) and also plug the disconnected heater hose. Start the engine and run until the water runs clear from the heater outlet.

A more thorough cleaning will require the radiator to be removed and laid flat on the floor. This is definitely a kill or cure process but no less risky than using a caustic additive.. The results are usually quite impressive but beware - you and anyone nearby is likely to get wet.

I have the poor-man's pressure washer, officially entitled a water-air gun, but as long as the radiator is filled with water and water is running through it and the inlet is sealed apart from the water-air gun or other arrangement that allows compressed air to be introduced into the filled radiator while water continues to flow will have the desired effect. I kneel on the radiator to keep it stable and sometimes I feel it grow under me when I give it the full air tank pressure.

If it breaks, the reason is it wasn't much good in the first place...

3.0L Engine

VIN S Engine

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.

check, temperature of upper radiator hose vs. lower radiator hose, also if there are any cold spots in radiator usaully indicates bad thermostat. all hoses and surface of radiator should be hot in order to keep engine cool

Check the radiator-it may have blockage. Take it off and turn upside down and flush from the bottom.
If the top hose gets hot, that means the thermostat is opening. The bottom hose should be at least warm, and quite warm if radiator flow is good.

!st check and make sure the water is flowing in the radiator, then check
the timeing, Mazda will run hot if the timeing is rong.

Section 303-03: Cooling, Engine 1997 Explorer, Mountaineer Workshop Manual REMOVAL AND INSTALLATION Radiator - 4.0L Removal

1. NOTE: Refer to following illustrations.
   Drain the cooling system by removing the radiator cap (8100) and attaching a 9.5 mm (3/8 inch) inside diameter hose to the draincock nipple, located at the lower rear corner of the radiator tank. Then, open the radiator draincock (8115) and allow the coolant to flow through the hose into a suitable container.

1. Loosen hose clamps at throttle body and engine air cleaner assembly. Remove air cleaner outlet tube and position aside.

1. Remove radiator overflow hose from the radiator, disconnect two hose locators at top of radiator and position hose aside.

1. Remove two fans shroud bolts. Lift the fan shroud out of the lower retaining clips and position it on the fan blade.

1. Position upper and lower radiator hose clamps, remove hose from radiator and position it on the fan blade.

1. Disconnect the two transmission cooling lines from the oil cooler fittings on the radiator, install protective caps over lines and position aside.

1. Remove two upper radiator bolts.

1. Tilt the radiator back (rearward) approximately 25 mm (one inch) and lift directly upward, clear of the radiator support bracket and the fan blade.

Remove the radiator.

first undo the hoses, there are 4 water hoses and 2 oil hoses, the bottom hose is difficult on the high side because of the alternator.
un plug the 2 wire connections (don't forget the locking tabs) then undo the air duct held by 2 screws. followed by 2 bolts located on the top of the radiator and lift the fans straight up
there are 2 larger bolts that hold the radiator in at the top. lift straight up.
when replacing be sure to place in locators in the bottom of radiator and fans
