Product Description
GM 12586768 58X Crankshaft Reluctor Wheel - 58-Tooth Crankshaft Position Sensor Trigger Wheel
Primarily Used on 2006-Newer GM Vehicles Equipped with a Gray Crankshaft Position Sensor
Match your crankshaft and engine-management system with the correct 58X crankshaft reluctor wheel. GM part number 12586768 features the 58-tooth crank trigger pattern primarily used on 2006-newer GM vehicles. As the crankshaft rotates, the reluctor wheel provides the position reference read by the crankshaft position sensor, allowing the engine-management system to identify crankshaft position. Because 24X and 58X systems use different trigger wheels, confirming the crank sensor color before ordering provides a quick way to identify the system installed in the engine.
Key Features & Benefits
- 58X Crank Trigger Configuration: Features the 58-tooth reluctor pattern required for compatible 58X crankshaft position systems. The wheel rotates with the crankshaft to create the position reference detected by the corresponding crankshaft sensor.
- GM Part Number 12586768: Identified by GM part number 12586768 for accurate product sourcing and replacement-part identification. The part number and 58X designation help distinguish this wheel from the earlier 24X crankshaft reluctor design.
- Common 2006-Newer GM Application: The 58X crankshaft reluctor system was primarily used on GM vehicles beginning with the 2006 model year. Because application transitions can vary, the crankshaft position sensor provides an additional visual method for identifying the existing trigger system.
- Gray Sensor Identifies 58X Systems: Compatible 58X systems use a gray crankshaft position sensor, while 24X systems use a black sensor. Checking the sensor color helps determine which crankshaft reluctor wheel configuration is present before purchasing replacement components.
- Accessible System Identification: The crankshaft position sensor is located at the rear of the engine block on the passenger side, near the oil pan and directly above the starter. This location can be inspected to confirm whether the engine uses the gray 58X sensor or black 24X sensor.
Key Fitments
- Primarily used on 2006+ GM Vehicles equipped with a 58X crankshaft position system
