WARNING: Never 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, engine 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).
CAUTION: The coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated, it must be recycled or disposed of correctly.
CAUTION: Some vehicle cooling systems are filled with Motorcraft Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or equivalent meeting Ford specification ESE-M97B44-A (green color). Others are filled with Motorcraft Premium Gold Engine Coolant VC-7-A or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Always fill the cooling system with the same coolant that is present in the system. Do not mix coolant types.
NOTE: Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement. When refilling the cooling system after draining, adjust the coolant mix ratio to obtain a 50/50 mix. Be certain to account for approximately 4.8L (5.1 quarts) of water left in the cylinder bloc .
1. Make sure the engine is cool.
2. Wrap a thic cloth around the coolant pressure relief cap on the coolant reservoir. Slowly turn the cap countercloc wise (left) until the pressure begins to release.
3. Step bac while the pressure releases.
4. When you are sure all the pressure has been released, use the cloth to turn and remove the cap.
5. Place a suitable container below the radiator draincoc (8115). If equipped, disconnect the coolant return hose at the fluid cooler.
6. Open the radiator draincoc to drain the coolant from the engine cooling system.
● Close the radiator draincoc when finished.
7. NOTE: Carry out this step only if a complete drain at the cylinder bloc is necessary.
- Loosen the bolts and allow the coolant to drain.
● Tighten the bolts when finished.
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 without RADKITPLUS
CAUTION: Engine 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 Engine Coolant VC-4-A (VC-5 in Oregon or Motorcraft CXC-10 in Canada) or an equivalent meeting Ford specification ESE-M97B44-A (green color), or Motorcraft Premium Gold Engine Coolant VC-7-A or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color).
Do not mix coolant types.
● Do not add orange-colored Motorcraft Specialty Orange Engine Coolant VC-2 or equivalent, meeting Ford specification WSS-M97B44-D. Mixing coolants may degrade the coolants 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.
● Do not mix with recycled coolant unless it meets the requirements of Ford specification ESE-M97B44-A or WSS-M97B51-A1. Not all coolant recycling processes meet these Ford specifications. Use of such coolants can harm the engine and cooling system components. Do not mix coolant types.
1. Check all hose clamps for correct tightness and ma e sure the radiator draincoc is closed.
2. Place the heater temperature selector to maximum heat position.
3. Remove the pressure cap from the degas bottle and the fill plug from the engine crossover tube.
4.CAUTION: Do not fill the cooling system through the degas bottle only. Coolant will not enter the engine. Only the reservoir and the radiator will be filled and engine overheating will occur.
Add coolant into the fill nec on the engine crossover tube until coolant reaches the top of the fill nec on the cooling system degas bottle.
5. Install the cooling system pressure cap on the degas bottle.
6. Continue to fill the cooling system at the engine crossover fill nec until full.
7. Install the engine crossover tube fill plug.
8.WARNING: To avoid the possibility of personal injury or damage to the vehicle, do not operate the engine with the hood open until the fan has been first examined for possible cracks and separation.
CAUTION: If the engine temperature gauge does not move, coolant level is low in the engine and must be filled. Stop the engine, allow to cool, and fill the cooling system as outlined.
Run the engine until the thermostat opens (coolant flowing through the radiator lower hose becomes hot).
9. Stop the engine and allow to cool.
10. Remove the engine crossover tube fill plug.
11. Add coolant to the engine crossover tube fill nec until the cooling system is full.
12. Install the fill plug.
13. Repeat the fill procedure if necessary.
Bleeding without RADKITPLUS
1. Select the maximum heater temperature and blower motor speed settings. Position the control to discharge air at A/C vents in instrument panel (04320).
2. Start the engine and allow to idle. While engine is idling, feel for hot air at A/C vents.
3.CAUTION: If air discharge remains cool and engine coolant temperature gauge does not move, engine coolant level is low in engine and must be filled.
Stop engine, allow to cool and fill cooling system.
Start engine and allow to idle until normal operating temperature is reached. Hot air should discharge from A/C vents. The engine coolant temperature gauge should maintain a stabilized reading in the middle of the NORMAL range and the upper radiator hose (8260) should feel hot to the touch.
4. Shut the engine off and allow to cool.
5. Check the engine for coolant lea s.
6. Check the engine coolant level in degas bottle and fill as necessary.
