Notice: In order to prevent damage to the crankshaft position (CKP)
sensor reluctor wheel/ring, care must be used when removing or installing this component.
Important: The crankshaft position sensor is designed to contact the reluctor wheel
of the crankshaft. Wear may be noticeable on the end of the sensor.
- Remove the crankshaft position sensor bolt.
- Apply penetrating oil to the crankshaft position sensor-to-engine
block mating surface. Allow the penetrating oil to soak for several minutes,
to help loosen the O-ring from the engine block.
- Twist the sensor to break the O-ring seals loose. When removing
the sensor, pull the sensor straight out of the engine block at the same
angle the sensor was installed.
- Inspect both crankshaft position sensor O-rings for cuts, cracks,
tears or damage. Replace the O-rings as needed.
Important: Crankshaft bearing caps are machined with the engine block for the proper
clearances. Mark or identify each crankshaft bearing cap location and direction
before removal. Crankshaft bearing caps must be installed in their original
locations.
- Remove the crankshaft bearing cap bolts and studs.
- Remove the crankshaft
bearing caps.
- Remove the crankshaft lower bearings from the crankshaft bearing
caps.
Important: Care should be taken when removing the crankshaft so that the crankshaft
position sensor reluctor ring is not damaged.
- Remove the crankshaft.
- Remove the crankshaft upper bearings from the engine block.
