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.

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."""
