Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Generators & Regulators: Overhaul
Other than replacing voltage regulator (where possible), manufacturer recommends replacing generator as an assembly. Overhaul procedures are not available. Diesel vehicles may be equipped with a generator pulley freewheeling clutch. Freewheeling clutch must be removed from old generator, and installed on new unit. Use multipoint socket (3310) to remove and install generator pulley or freewheeling clutch. On Diesel vehicles equipped with Valeo generator, pulley cannot be refitted. Replace Valeo generator with a Bosch generator. On vehicles built from May 1999 and on, belt pulley with freewheel is identical from various manufacturers.
