Cooling System: Service and Repair
Cooling System Draining, Filling and Bleeding
Special Tool(s)
Draining
WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.
NOTICE: 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. Failure to follow these instructions may result in engine or cooling system damage.
NOTE:
- Less than 80% of the coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.
- During normal vehicle operation, Motorcraft Orange Antifreeze/Coolant may change color from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color change does not indicate the engine coolant has degraded nor does it require the engine coolant to be drained, the system to be flushed, or the engine coolant to be replaced.
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Make sure the engine is cool.
3. Wrap a thick cloth around the pressure relief cap. Slowly turn the cap counterclockwise until the pressure begins to release.
4. Step back while the pressure releases.
5. When sure all the pressure has been released, use the cloth to turn and remove the cap.
6. Place a suitable container below the radiator draincock. Drain the coolant.
- Tighten the radiator draincock when finished.
Filling and Bleeding with a Vacuum Cooling System Filler - Degas Bottle Systems
NOTICE:
- The engine cooling system is filled with Motorcraft(R) Orange Antifreeze/Coolant. Always fill the cooling system with the manufacturer's specified coolant. Chemically flush the cooling system if a non-specified coolant has been used. Refer to Cooling System Flushing. Failure to follow these instructions may damage the engine or cooling system.
- Engine coolant provides boil protection, corrosion protection, freeze protection, and cooling efficiency to the engine and cooling components. In order to obtain these protections, maintain the engine coolant at the correct concentration and fluid level in the degas bottle.
To maintain the integrity of the coolant and the cooling system:
- Add Motorcraft(R) Orange Antifreeze/Coolant or equivalent. Do not mix coolant types.
- Do not add or mix with any other type of engine coolant. Mixing coolants may degrade the coolant's corrosion protection.
- Do not add alcohol, methanol, or 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(R) Orange Antifreeze/Coolant since a Ford-approved recycling process is not yet available.
1. Install the vacuum cooling system filler and follow the manufacturer's instructions to fill and bleed the cooling system.
When adding or topping of the engine coolant:
1. Measure the coolant concentration in the vehicle using the Coolant/Battery Refractometer 300-ROB75240 or equivalent.
2. Determine the concentration desired based on the vehicle duty cycle of extreme hot or cold operating conditions.
3. Add/top off or adjust coolant as follows:
- For concentrations measured 48/52 to 50/50 (equates to a freeze point between -31° C [-30° F] and -34° C [-37° F]), use Motorcraft(R) Orange Antifreeze/Coolant Prediluted to maintain a coolant concentration in this same range.
- For all other concentrations, use Motorcraft(R) Orange Antifreeze/Coolant Concentrated and/or distilled water to get to the desired concentration.
- When refilling the engine coolant after a flush procedure, use a mixture of Motorcraft(R) Orange Antifreeze/Coolant Concentrated and distilled water to get to the desired concentration.
4. Recommended coolant concentration is 48/52 to 50/50 engine coolant to distilled water (freeze protection -31° C [-30° F] to -34° C [-37° F]).
5. For extremely cold climates (less than -37° C [-34° F]):
- It may be necessary to increase the coolant concentration above 50%.
- NEVER increase the coolant concentration above 60%.
- Maximum coolant concentration is 60/40 for cold weather areas.
- A coolant concentration of 60% provides freeze point protection down to -50° C (-58° F).
- Engine coolant concentration above 60% decreases the overheat protection characteristics of the engine coolant and may damage the engine.
6. For extremely hot climates:
- It is still necessary to maintain the coolant concentration above 40%.
- NEVER decrease the coolant concentration below 40%.
- Minimum coolant concentration is 40/60 for warm weather areas.
- A coolant concentration of 40% provides freeze point protection down to -26° C (-15° F).
- Engine coolant concentration below 40% decreases the corrosion and freeze protection characteristics of the engine coolant and may damage the engine.
7. Vehicles driven year-round in non-extreme climates should use a 48/52 to 50/50 mixture of engine coolant and distilled water (freeze protection -31° C [-30° F] to -34° C [-37° F]) for optimum cooling system and engine protection.
