2003 Lincoln Navigator Alternator Parts Q&A
Q: How to Address Issues with the Alternator and What Steps Are Involved for a 2003 Lincoln Navigator?
A: Service and repair of the alternator must start with disconnecting the battery. The noble step is to pull out both the radiator shroud and cooling fan. Release the strain on the accessory drive belt followed by removing it from the generator pulley. Follow this procedure: lower generator bolts should be made loose before disconnecting the harness pin-type retainer from the water-neck housing. First remove the generator bracket retaining bolts after which you can carefully set the generator to the side. Protocols must apply to new style connector connectors with press-to-release tabs because tab pulling can harm the connector or harness structure. Cable the B+ electrical component off and detach its nut and cable before disconnecting the electrical connector. Afterward remove the generator. You should reverse the steps taken for removal during the installation process.
