1. Disconnect engine coolant temperature sensor electrical connector and inspect sensor and connector terminals for corrosion and/or evidence of engine coolant. ^If terminals are corroded or if there is evidence of engine coolant proceed to step 4. ^If terminals are not corroded and there is no evidence of engine coolant, reconnect the electrical connector and continue to next step. 2. Perform one or both of the following checks to determine whether the engine coolant temperature sensor is providing the correct temperature indication. If engine coolant temperature sensor reading does not pass either of the above tests, continue with next step. ^If engine is at ambient temperature (vehicle has been sitting overnight or not started for several hours), use a Scan tool to compare the inlet air temperature ( IAT ) to the engine coolant temperature ( ECT ). These two readings should be within 2°C (4°F) of each other. ^If engine is at operating temperature, install a thermometer in the coolant recovery reservoir. With the engine running and A/C off, use a Scan tool to compare the engine coolant temperature sensor reading to the thermometer reading. These two readings should be within 8°C (15°F) of each other If engine coolant temperature sensor reading passes both of the tests above, refer to appropriate symptom diagnostic chart in the Engine/Emissions Controls Section of applicable Engine Service Manual. 3. Turn ignition off. 4Remove coolant surge tank cap. 5. Drain at least 1.9 L (2 Qt.) of engine coolant from the cooling system by opening radiator drain valve or removing engine drain plug. Collect engine coolant in a container. 6. Disconnect engine coolant temperature sensor electrical connector. 7. Remove engine coolant temperature sensor from cylinder head. 8. Obtain replacement engine coolant temperature sensor (P/N 21025106). 9. Use appropriate tap to clean sensor mounting hole of any thread sealant residue. 10.

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.

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.

Draining and Filling Cooling System Notes Draining and Filling Cooling System Draining Procedure Important: Do NOT add any engine coolant supplement sealant pellets to the cooling system. Drain and refill the engine cooling system every 5 years or 240 000 km, (150,000 ml) , whichever occurs first. 1. Park the vehicle on a level surface. 2. Remove and clean the coolant recovery reservoir. Caution: To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap its removed while the engine and radiator are still hot. 3.1. Slowly rotate the cap counterclockwise to the detention tab. Do not press down while rotating pressure cap. 3.2. Wait until any residual pressure, indicated by a hissing sound, is relieved. 3.3. After all hissing stops, press down on the radiator cap and rotate the cap counterclockwise in order to remove the cap. Important: Recover and store used coolant in a used coolant holding tank and submit the used coolant for recycling on a regular basis. Do NOT pour used coolant down the drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into the sewer system or ground water is both illegal and ecologically unsound. 4. Place a drain pan under the radiator drain cock in order to collect all of the used coolant. 5. Open the radiator drain cock. If only partial cooling system draining is required, drain enough coolant to perform the procedure 6. Open the air bleed valve on the thermostat housing 2 full turns. 7. Open the air bleed valve above coolant pump 2 full turns. 8. Place a drain pan under the engine block drains in order to collect the used coolant. Important: Allow the coolant to drain completely

Some vehicles may experience a gradual coolant loss over time. A very low percentage of cylinder head(s) manufactured with an embossed Castech logo may develop a porosity crack in a very specific area. Inspect the cylinder head assembly to determine if the casting was manufactured by Castech. This can be accomplished by inspecting for their casting logo located on top of the intake port, under the rocker arm support rail and in the spring deck cavity portion of the cylinder head. Important: If the cylinder head(s) are Not a Castech casting, follow normal diagnostic procedures in SI to determine the cause of the coolant loss. Refer to the following illustrations on how to identify Castech casting and/or the very specific areas of the cylinder head(s) for a coolant leak from porosity. If the cylinder head(s) is a Castech casting (1), inspect the area around the five oil drain holes for witness marks indicating coolant seepage over time (2). Important: If No evidence of coolant loss is found on inspection of Castech casting cylinder head (s), follow normal diagnostic procedures in SI to determine the cause of the coolant loss
