CAUTION: Vehicle cooling systems are filled with Motorcraft Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or an equivalent meeting Ford specification ESE-M97B44-A. NOTE: Less than 80% of the coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement. 1. Release the pressure in the cooling system by slowly turning the pressure relief cap one half to one turn counterclockwise to the first stop on the filler neck. When the pressure has been released, remove the pressure relief cap. 2. Raise and support the vehicle. For additional information, refer to Section 100-02 . 3. Remove the front splash shield. 4. Place a suitable container below the radiator draincock. Drain the coolant. 5. Close the radiator draincock 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. 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 (in Oregon VC-5, in Canada CXC-10) or equivalent meeting Ford specification ESE-M97B44-A. * Do not add Motorcraft Specialty Engine Coolant VC-2 or an equivalent meeting Ford specification WSS-M97B44-D. 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. * Do not mix with recycled coolant unless it meets the requirement of specification ESE-M97B44-A. Not all coolant recycling processes meet this specification. Use of such a coolant may harm the engine and cooling system components. 1. Install the front splash shield. 2. Lower the vehicle. 3. Fill the degas bottle with the correct engine coolant mixture. 4. Install the pressure relief cap. 5. Move the temperature blend selector to the full warm position. 6. WARNING: Do not stand in line with or near the engine cooling fan blade when revving the engine. Run the engine until it reaches operating temperature. 7. Add the correct coolant mixture to the degas bottle until the coolant level is between the COOLANT FILL LEVEL marks. 8. Turn off the engine and allow the cooling system to cool. Recheck the coolant level and fill the cooling system to the FULL mark on the degas bottle. 9. WARNING: Do not stand in line with or near the engine cooling fan blade when revving the engine. Repeat Steps 3 through 8 until the reservoir level is OK. Bleeding Without RADKITPLUS 1. Bleed the cooling system as follows: * Select the maximum heater temperature and blower motor speed settings. Position the control to discharge air from the A/C vents in the instrument panel. * WARNING: Do not stand in line with or near the engine cooling fan blade when revving the engine. Start the engine and allow it to idle. While the engine is idling, feel for hot air from the A/C vents. * CAUTION: If the air discharge remains cool and the engine coolant temperature gauge does not move, the engine coolant level is low in the engine and must be filled. Stop the engine, allow it to cool and fill the cooling system. Start the engine and allow it to idle until the normal operating temperature is reached. Hot air should discharge from the 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 should feel hot to the touch. * Shut the engine off and allow it to cool. * Check the engine for coolant leaks. * Check the engine coolant level in the degas bottle and fill it as necessary.
CCV Fitting See Figures 2 and 3 1. With the engine running, remove the CCV fitting. a. If the fitting is not plugged, a hissing noise will be heard as air passes through the valve. A strong vacuum should also be felt when a finger is placed over the fitting. b. Install the CCV fitting. c. Remove the fresh air hose from the air cleaner assembly and loosely hold a piece of paper over the open end of the hose. After allowing about one minute for the crankcase pressure to reduce, the paper should be sucked against the opening with a noticeable amount of force. 2. Turn the engine OFF . Remove the metered orifice fitting, and check for a plugged condition. A clicking noise should be heard to indicate that the valve mechanism is free. 3. If the crankcase ventilation system meets the tests in Steps 1 and 2 above, no further service is required. If not, the CCV fitting must be cleaned and the system checked again. 4. If Step 1c fails when the CCV fitting is cleaned, it will be necessary to replace the molded vacuum hose with a new one, and to clean the metered orifice port. 5. Clean or replace the engine air cleaner filter element with a new one-for more details, refer to the air cleaner procedure located in General Information & Maintenance. Fig. 2: CCV system diagram for 4.0L engine Fig. 3: CCV system diagram for the 2.5L engine Evaporative Emission Control System OPERATION The evaporative emission control system prevents the release of unburned hydrocarbons, from gasoline or gasoline vapor, into the atmosphere. When pressure in the fuel tank is below 3 psi (20 kPa), the pressure relief/rollover valves open allowing fuel vapors to flow to the evaporative canister where they are absorbed by a charcoal mixture. This prevents excessive pressure buildup in the fuel system. Most canisters are equipped with a calibrated orifice at the inlet to the canister.
