Possible Causes

  1. An open circuit 1823 (YE/BK), 1822 (LB), 538 (GY/RD), 3829 (LB/BK), 229 (RD/OG) or 57 (BK)
  2. A short to voltage on circuit 538 (GY/RD), 3829 (LB/BK) or 229 (RD/OG)
  3. Cooling fan relay
  4. Cooling fan motor
  5. Cooling fan resister

Cap

WARNINGNever remove the pressure relief cap under any conditions while the engine is operating. Failure to follow these instructions can 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, use extreme care when removing the pressure relief cap from a hot degas bottle. Wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly one turn (counterclockwise). Step back while the pressure is released from the cooling system. When certain all the pressure has been released, remove the pressure relief cap (still with a cloth).
  1. Remove the pressure relief cap from the degas bottle.
  2. Immerse the pressure relief cap in water and install it on the shallow filler neck of the Radiator/Heater Core Pressure Tester and the Radiator Cap Adapter, part of the Radiator/Heater Core Pressure Tester.
  3. Immerse the filler neck seal in water and install it in the filler neck adapter.
  4. Install the filler neck adapter with the filler neck seal to the Radiator Cap Adapter.
  5. Connect the female quick connect fitting of the pressure test pump to the male quick connect fitting of the filler neck adapter.
  6. Slowly depress the plunger of the pressure test pump until the pressure gauge reading stops increasing and note the highest pressure reading obtained.
  7. Release the pressure by turning the relief screw counterclockwise. Then tighten the pressure relief screw and repeat Step 6 (at least twice) to make sure the reading is repeatable within the specifications of the pressure relief cap.
  8. If the pressure test gauge readings are not within specifications, install a new pressure relief cap. If the pressure test gauge readings are within specifications, carry out the cooling system Pressure Test.

Thermostat

A new thermostat should be installed only after the following mechanical test has been carried out.

Thermostat - Mechanical Test

  1. Remove the thermostat housing.
  2. Immerse the thermostat housing and thermostat in a boiling antifreeze and water mixture.
  3. See the «GENERAL SPECIFICATIONS CHART»(ref-232208-S09920949892006051600000) for thermostat opening temperatures.

Cooling Fan Motor and Shroud

  1. Inspect the fan blade and shroud for any foreign materials. Clear the obstruction and continue the test procedure.
  2. Rotate the fan to see if any contact between the shroud and blade exists. If contact is observed, install a new fan shroud assembly.
  3. Rotate the fan by hand. The fan should rotate freely (no resistance should be felt, the fan will free-wheel with minimum effort). If any resistance is present, install a new fan assembly.

Material

ItemSpecification
Motorcraft Premium Gold Engine Coolant VC-7-A (in California, Oregon and New Mexico VC-7-B, in Canada CVC-7-A) or equivalent (yellow color)WSS-M97B51-A1

ITEM SPECIFICATION

Filling and Bleeding with RADKITPLUS

  1. Using the special tool, install the RADKITPLUS and follow the manufacturer's instructions to fill and bleed the cooling system.

Filling and Bleeding without RADKITPLUS

CAUTIONEngine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle. When adding engine coolant, use a 50/50 mixture of engine coolant and distilled water. To maintain the integrity of the coolant and the cooling system: Vehicle cooling systems are filled with Motorcraft Premium Gold Engine Coolant. Always fill the cooling system with the same coolant that is present in the system. Do not mix coolant types. Do not add/mix orange-colored Motorcraft Specialty Orange Engine Coolant VC-2 or equivalent meeting Ford specification WSS-M97B44-D or green colored Premium Engine Coolant. Mixing coolants may degrade the coolant's corrosion protection. Do not add alcohol, methanol, brine or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing. Ford Motor Company does NOT recommend the use of recycled engine coolant in vehicles originally equipped with Motorcraft Premium Gold Engine Coolant since a Ford-approved recycling process is not yet available. Used engine coolant should be disposed of in an appropriate manner. Follow your community's regulations and standards for recycling and disposing of automotive fluids.

Note. The addition of Cooling System Stop Leak Pellets VC-6 or equivalent meeting Ford specification WSS-M99B37-B6 darkens Motorcraft Premium Gold Engine Coolant from yellow to golden tan.

  1. Add the correct engine coolant mixture to the degas bottle until the coolant level is between the "COOLANT FILL LEVEL" marks.
  2. Select the maximum heater temperature and blower motor speed settings. Position the control to discharge air at vents in the instrument panel.
  3. Start the engine and allow to idle. While engine is idling, feel for hot air at vents.
  4. Start the engine and allow to idle until normal operating temperature is reached. Hot air should discharge from vents. The engine coolant temperature gauge should maintain a stabilized reading in the middle of the NORMAL range and the upper radiator hose should feel hot to the touch.
  5. Shut the engine OFF and allow to cool.
  6. Check the engine for coolant leaks.
  7. Check the engine coolant level in degas bottle and fill as necessary.
