CHANGING THE ENGINE AIR FILTER – 6.7L DIESEL

Air Filter Restriction Gauge

WARNING: To reduce the risk of vehicle damage and personal burn injuries, do not start your engine with the air cleaner removed and do not remove it while the engine is running.

Note: Operating your vehicle in heavy snowfall or extreme rain conditions may allow excessive amounts of snow or water into the air intake system. This could plug or soak the air filter and cause the engine to lose power or shut down.

The restriction gauge, on the upper housing of the air filter assembly, measures the vacuum inside the air filter. The more the air filter is dirty or clogged, the higher the vacuum reading. Check the air filter restriction gauge whenever you open the hood to perform general engine maintenance or at least every 7,500 mi (12,000 km). If you operate your vehicle in extremely dusty conditions, check and reset the gauge at least every 500 mi (800 km), or two weeks, whichever comes first. Change the air filter when the restriction gauge reads near the change filter line and the gauge is yellow. If you allow the restriction gauge to reach maximum restriction, you can affect your engine performance and fuel economy.

Note: Do not blow out the air filter element with compressed air since the compressed air could damage the filter paper.

Note: Do not rely on filter appearance alone. A filter which appears to be dirty may have several thousand miles (kilometers) of life remaining.

After installation of the new filter element, reset the gauge by pressing the reset button on top of the gauge.

We recommend the following actions after operating the vehicle up to 200 mi (320 km) in heavy snowfall or extreme rain:

1. Snow: At the earliest opportunity, open the hood and clear all the snow and ice from the air filter housing inlet. Do NOT remove the foam filter and reset the air filter restriction gauge.
2. Extreme rain: The air filter dries after about 15–30 minutes at highway speeds. At the earliest opportunity, open the hood and reset the air filter restriction gauge.

Air Filter Replacement
When replacing the air filter element, use a Motorcraft® air filter element. See Motorcraft Parts (page 292).

Note: Failure to use the correct air filter element may result in severe engine damage.

1. Locate the mass airflow sensor electrical connector on the air inlet tube. Disconnect the electrical connector. Unlock the locking clip on the connector, then squeeze and pull the connector off the air inlet tube.
2. Remove the clips that secure the air filter housing cover. Push the air filter cover forward and away from you when pulling up slightly to release it.
3. Remove the air filter element from the air filter housing.
4. Remove and install a new foam filter, if needed. See Scheduled Maintenance (page 324). If you do not replace the foam filter, be sure the existing foam filter is in place.
5. Install a new air filter element. Be sure that the groove seal on the pleated paper filter traps both sides of the vertical partition of the air box.
6. Engage the clips to secure the air filter housing cover to the air filter housing. Be careful not to crimp the filter element edges between the air filter housing and cover. Ensure that you align the tabs on the edge properly into the slots.
7. Reconnect the mass airflow sensor electrical connector to the inlet tube. Make sure the locking tab on the connector is in the locked position.

CHANGING THE ENGINE AIR FILTER – 7.3L

WARNING: To reduce the risk of vehicle damage and personal burn injuries, do not start your engine with the air cleaner removed and do not remove it while the engine is running.

Note: Operating your vehicle in heavy snowfall or extreme rain conditions may allow excessive amounts of snow or water into the air intake system. This could plug or soak the air filter, and cause the engine to lose power or shut down. When replacing the air filter element, use a Motorcraft® air filter element.

Note: Failure to use the correct air filter element may result in severe engine damage, and may void the vehicle warranty. Change the air filter element at the correct interval.

1. Locate the mass air flow sensor electrical connector on the air outlet tube. Disconnect the mass air flow sensor electrical connector.
2. Reposition the locking clip on the connector, squeeze the connector and pull it off the air outlet tube.
3. Clean the area from around the air tube to the air cover connection to prevent debris from entering the system. Next, loosen the bolt on the air tube clamp so the clamp is no longer snug to the air tube. It is not necessary to completely remove the clamp.
4. Pull the air tube off from the air cleaner housing.
5. Remove the clips that secure the air filter housing cover. Push the air filter cover toward the center of the vehicle and up slightly to release it.
6. Remove the air filter element from the air filter housing.
7. Install the new air filter element.
8. Engage the clips to secure the air filter housing cover to the air filter housing. Be careful not to crimp the filter element edges between the air filter housing and cover. Ensure that you align the tabs on the edge properly into the slots.
9. Slip the air tube onto the air filter housing and tighten the air-tube clamp bolt snugly. Do not over tighten air-tube clamp bolt.
10. Reconnect the mass air flow sensor electrical connector to the outlet tube. Make sure the locking tab on the connector is in the locked position.

DRAINING THE FUEL FILTER WATER TRAP – 6.7L DIESEL
Your vehicle is equipped with a diesel fuel conditioner module located on the frame-rail under the driver-side floorboard near the transmission.

You should drain water from themodule assembly whenever the warning light comes on and the message center directs you to drain the water separator. This will occur when approximately 8.45 fl oz (250 ml) of water accumulates in the module. If you allow the water level to exceed this level, the water may pass through to the engine and may cause fuel injection equipment damage.

Draining the Diesel Fuel Conditioner Module (DFCM)

WARNING: Do not drain the water-in-fuel separator while the engine is running. Failure to follow this warning may result in fire, serious injury, death or property damage.

Note: If you drain the diesel fuel conditionermodule while the system is running air will enter into the fuel system. The engine will not operate properly if air enters the system.

Note:With fuel tank levels above 3⁄4 tank it may be necessary to loosen the bowl three turns before opening the drain. This will actuate an anti-siphon valve at the fuel and water separator inlet and prevent the fuel from siphoning out of the tank.

Note: A loose drain valve can allow air to enter the fuel system and cause drivetrain issues. The engine will not operate properly. Be sure that you fully tighten the drain valve.

1. Stop your vehicle and shut off the engine.
2. Locate the diesel fuel conditioner module and place an appropriate container under the drain port.
3. Rotate the drain counterclockwise until the O-ring is visible. Allow the diesel fuel conditioner module to drain for approximately 25 seconds or until clean fuel is observed. Rotate the drain clockwise to tighten it. If no liquid drains, there may be a clog in the drain. Have the conditioner module serviced by an authorized dealer.
4. Make sure that you fully tighten thedrain valve and then remove the container from under your vehicle.
5. Restart the engine. If the Water in Fuel Drain Filter message and light continues to illuminate, have the fuel system checked and repaired.

ENGINE COOLANT CHECK – 6.7L DIESEL

WARNING: Do not remove the coolant reservoir cap when the engine ison or the cooling system is hot. Wait 10 minutes for the cooling system to cool down. Cover the coolant reservoir cap with a thick cloth to prevent the possibility of scalding and slowly remove the cap. Failure to follow this instruction could result in personal injury.

WARNING: To reduce the risk of personal injury, make sure the engine is cool before unscrewing the coolant pressure relief cap. The cooling system is under pressure. Steam and hot liquid can come out forcefully when you loosen the cap slightly.

When the engine is cold, check the concentration and level of the coolant at the intervals listed in the scheduled maintenance information. See Scheduled Maintenance (page 324).

Note: Make sure that the coolant level is between the MIN and the MAX marks on the coolant reservoir.

Note: Coolant expands when it is hot. The level may extend beyond the MAX mark. Maintain coolant concentration within 48% to 50%, which equates to a freeze point between -30°F (-34°C) and -34°F (-37°C). Coolant concentration should be checked using a refractometer. We do not recommend the use of hydrometers or coolant test strips for measuring coolant concentration.

Adding Coolant

WARNING: Do not put coolant inthe windshield washer reservoir. If sprayed on the windshield, coolant could make it difficult to see through the windshield.

WARNING: Do not add coolant further than the MAX mark.

WARNING: Do not add coolant when the vehicle is on or the cooling system is hot. Failure to follow this instruction could result in personal injury.

WARNING: Do not remove the coolant reservoir cap when the engine is on or the cooling system is hot. Wait 10 minutes for the cooling system to cool down. Cover the coolant reservoir cap with a thick cloth to prevent the possibility of scalding and slowly remove the cap. Failure to follow this instruction could result in personal injury.

Note: Automotive fluids are not interchangeable. Do not use coolant or windshield washer fluid outside of its specified function and vehicle location.
