Inspection and Verification
WARNING: This page is about a different variant/trim than selected.
NOTE:
The engine cooling system is filled with Motorcraft® Orange Antifreeze/Coolant. Always fill the cooling system with the manufacturer's specified coolant. Chemically flush the cooling system if a non-specified coolant has been used. Failure to follow these instructions may damage the engine or cooling system.
NOTE:
During normal vehicle operation, Motorcraft Orange Antifreeze/Coolant may change color from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color change does not indicate the engine coolant has degraded nor does it require the engine coolant to be drained, the system to be flushed, or the engine coolant to be replaced.
- 4.
Record any cooling system Diagnostic Trouble Codes (DTCs) retrieved. Refer to the PCM DTC Chart for DTC descriptions.
- 5.NOTE: Take note of any coolant odor or steam coming from cooling system components.
If the system coolant is filled correctly and no Diagnostic Trouble Codes (DTCs) associated with overheating are retrieved, verify the customer concern by operating the engine to duplicate the condition.
