286 COOLANT Maintenance Engine Coolant and Inverter System Controller Coolant Your vehicle is equipped with two separate cooling systems. One is for cooling the engine and one is for cooling the inverter system controller that is specific to the hybrid operating system. The two systems operate similarly, with the inverter system controller cooling system generally operating at a lower temperature and pressure. Checking the Engine Coolant When the engine is cold, check the concentration and level of the engine coolant at the intervals listed in the Scheduled Maintenance Information. Note: Make sure that the level is between the MIN and MAX marks on the engine coolant reservoir. Note: Coolant expands when it is hot. The level may extend beyond the MAX mark. Note: If the level is at the MIN mark, below the MIN mark, or empty, add prediluted coolant immediately. Refer to Adding Engine Coolant in this chapter. The coolant concentration should be maintained at 50%. Note: For best results, coolant concentration should be tested with a refractometer such as Rotunda tool ROB75240 available from your dealer. Ford does not recommend the use of hydrometers or coolant test strips for measuring coolant concentrations. Note: Automotive fluids are not interchangeable; do not use engine coolant/antifreeze or windshield washer fluid outside of its specified function and vehicle location. Checking the Inverter System Controller Coolant When the engine is cold, check the concentration and level of the inverter system controller coolant at the intervals listed in the Scheduled Maintenance Information. Note: Make sure that the level is between the MIN and MAX marks on the inverter system controller coolant reservoir. Note: Coolant expands when it is hot. The level may extend beyond the MAX mark. Note: If the level is at the MIN mark, below the MIN mark, or empty, add prediluted coolant immediately.

COOLANT
Engine Coolant and Inverter System Controller Coolant
Your vehicle is equipped with two separate cooling systems. One is for
cooling the engine and one is for cooling the inverter system controller
that is specific to the hybrid operating system. The two systems operate
similarly, with the inverter system controller cooling system generally
operating at a lower temperature and pressure.
Checking the Engine Coolant
When the engine is cold, check the concentration and level of the engine
coolant at the intervals listed in the
Scheduled Maintenance Information.
Note:
Make sure that the level is between the MIN and MAX marks on
the engine coolant reservoir.
Note:
Coolant expands when it is hot. The level may extend beyond the
MAX mark.
Note:
If the level is at the MIN mark, below the MIN mark, or empty,
add prediluted coolant immediately. Refer to
Adding Engine Coolant
in
this chapter.
The coolant concentration should be maintained at 50%.
Note:
For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool ROB75240 available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:
Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Checking the Inverter System Controller Coolant
When the engine is cold, check the concentration and level of the
inverter system controller coolant at the intervals listed in the
Scheduled
Maintenance Information.
Note:
Make sure that the level is between the MIN and MAX marks on
the inverter system controller coolant reservoir.
Note:
Coolant expands when it is hot. The level may extend beyond the
MAX mark.
Note:
If the level is at the MIN mark, below the MIN mark, or empty,
add prediluted coolant immediately. Refer to
Adding Inverter System
Controller Coolant
in this chapter.
