Cap

1. Inspect the pressure relief cap and seals for damage or deterioration. Install a new pressure relief cap if necessary.
2. Fit the pressure relief cap to the Radiator/Heater Core Pressure Tester Kit using the correct adapter.
3. Slowly pump the pressure tester until the pressure gauge stops increasing and note the highest pressure reading. Release the pressure and repeat the test. Install a new pressure relief cap if the pressure is not within specification. Refer to the General Specifications chart in this article.

Thermostat

A new thermostat should be installed only after the following tests and checks have been carried out

1. Pinpoint Test A, B or C
2. Thermostat Visual Inspection

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 and Bleeding without RADKITPLUS

Note. The addition of Motorcraft Cooling System Stop Leak Pellets, VC-6, darkens Motorcraft Premium Gold Engine Coolant from yellow to golden tan.

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

Note. The addition of Cooling System Stop Leak Pellets, VC-6, darkens Motorcraft Premium Gold Engine Coolant from yellow to golden tan.

1. Install the air deflector and the bolts. Tighten to 15 Nm (11 lb-ft).
2. Fill the overflow bottle with the correct engine coolant mixture.
3. Install the radiator cap.
4. Move the temperature blend selector to the full warm position.
5. Run the engine until it reaches operating temperature.
6. Add the correct coolant mixture to the overflow bottle until the coolant level is between the COOLANT FILL LEVEL marks.
7. 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 overflow bottle.
8. 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. A damaged fan can separate during operation. Failure to follow this instruction may result in serious personal injury. 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. Operating the engine with low coolant level may cause engine or cooling system component damage. 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 overflow bottle and fill it as necessary.
