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 electrical and mechanical tests have been carried out.

Thermostat - Electrical Test

Note. The electrical thermostat test is most accurate if carried out indoors at less than 37.8°C (100°F) ambient air. This test can be carried out with or without the hood open and with the engine warm or cold.

  1. Check the engine coolant level. Fill as needed.
  2. With the ignition OFF, attach the Rotunda 73 Digital Multimeter to the cylinder head temperature (CHT) sensor. It may be used to monitor sensor voltage values between 0-5 volts.
  3. Place the transmission in PARK (P) or NEUTRAL (N).
  4. Start the engine and allow the engine to idle throughout this test. Allow the engine to run for two minutes, then record the CHT voltage. Record the CHT voltage every 60 seconds. When the CHT voltage trend changes direction or only changes slightly (0.03 volt or less) from the previous reading, record this as the thermostat opening voltage. Use the voltage and corresponding coolant temperature chart listed below. See «COOLANT TEMPERATURE SPECIFICATION»(ref-207554-S08956696802005113000000) . COOLANT TEMPERATURE SPECIFICATION Coolant Temp °C (°F) CHT Min (Volts) CHT Nom (Volts) CHT Max (Volts) 0 (32) 4.7714 4.8032 4.8723 25 (77) 4.3428 4.4148 4.4727 50 (122) 3.5354 3.6495 3.7473 80 (176) 2.3049 2.4201 2.5260 110 (230) 1.3021 1.3808 1.4562 140 (284) 0.6960 0.7414 0.7857 170 (338) 0.3784 0.4024 0.4261
  5. If the thermostat opening temperatures are not between 89°C (192°F) and 104°C (219°F) or the corresponding voltages shown on the chart, install a new thermostat.
  6. If the thermostat opening temperatures and voltages are within the specified range, the thermostat is good and a new thermostat is not required. GO to the «SYMPTOM CHART»(ref-207554-S31411344822005113000000) .

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»(ref-207554-S42695114122005113000000) chart 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.

ITEM SPECIFICATION

Filling and Bleeding With RADKITPLUS

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

Filling and Bleeding Without RADKITPLUS

WARNINGDo not open the cooling system while it is hot or the engine is running. Failure to follow these instructions can result in personal injury.
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 clean, drinkable water. To maintain the integrity of the coolant and the cooling system: Add Motorcraft Premium Gold Engine Coolant VC-7-A (in California and Oregon VC-7-B, in Canada, VC-7-C) or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Use the same coolant that was drained from the cooling system. Do not mix coolant types. Do not add Motorcraft Speciality Orange Engine Coolant VC-2 meeting Ford specification WSS-M97B44-D (orange color). Mixing coolants can 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.
