Description

S3975 Replacement Starter Motor

For a S3975 starter motor enquiry, use Lucas reference LRS03975 alongside the vehicle and original unit details. The listed electrical rating is 12V 2.5kW. A starter motor turns the engine during starting; the electrical rating and mechanical engagement must suit the application. Applications include selected Porsche Cayenne 3.6 Petrol variants.

Key Features and Benefits

  • 12V electrical system: match the vehicle voltage before selecting a unit.
  • 2.5kW power: compare the listed rating with the original starter motor.
  • 10-tooth pinion: compare gear engagement and pinion position.
  • Clockwise rotation: check the specified direction before fitting.

Compatible Vehicles and Applications

  • Porsche Cayenne 3.6 Petrol – selected applications 2014–2018 (engine code MCURA).
  • Porsche Macan 3.0 Petrol – selected applications 2014–2018 (engine code MCTMA).

These are selected applications, not the complete fitment list. Check the detailed vehicle compatibility table, engine code and production year, then compare the original unit before ordering.

OE Numbers and Cross-Reference Information

The following cross-reference numbers are associated with S3975. Compare them with the original unit and technical specifications; a number match alone does not establish vehicle compatibility.

The full manufacturer cross-reference and OE listings are available elsewhere on this page. Confirm whether a number is an OE or aftermarket reference when comparing the original unit.

When Should You Replace Your Starter Motor?

Failure to crank, clicking during a start request or intermittent cranking can indicate a starting-system problem. A weak battery, poor connections or control-circuit faults can produce similar symptoms; test the system before replacing the starter motor.
