Engine Cooling: Other Ford Econoline E250

Thermostat

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

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

1. Add the correct engine coolant mixture to the degas bottle.
2. Move the temperature blend selector to the full warm position.
3. Run the engine until it reaches operating temperature.
4. Add the correct engine coolant mixture to the degas bottle until the coolant level is between the "COOLANT FILL LEVEL" marks.
5. Turn off the engine and allow the cooling system to cool.
6. Repeat Steps 1 through 5 until the degas bottle level is OK.

Bleeding without RADKITPLUS

1. Select the maximum heater temperature and medium low blower motor speed settings. Position the control to discharge air at the panel vents in the instrument panel.
2. Start the engine and allow to idle. While the engine is idling, feel for hot air at the panel vents.
3. Start engine and allow to idle until normal operating temperature is reached. Hot air should discharge from the panel 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.
4. Shut the engine off and allow to cool.
5. Check the engine for coolant leaks.
6. Check the engine coolant level in degas bottle and fill as necessary.
