Ford Hybrid Coolant Pump
Some 2013-2014 Ford Fusion Hybrid, MKZ Hybrid and Energi vehicles built on or before 9-2-13 may exhibit an illuminated wrench or engine lamp with DTC P26CA and/or U019F.
1. Disconnect C1812 at the coolant pump and inspect for evidence of moisture or corrosion on the harness connector and coolant pump terminals. Refer to wiring diagrams, section 33-1.
2. If moisture or corrosion is present, replace the coolant pump.
3. Replace the coolant pump connector with a pigtail kit following instructions in the kit. When installing the connector onto the coolant pump, ensure that the harness is routed as straight as possible to avoid damage to the connector.
