How do you replace acrankshaft position sensor on a 2005 town and country van and where is it located?

Ohhh this is a difficult one. The crankshaft is not easy to replace in any vehicle, and vans can be harder.

At least the drive belt is in the front of the motor. You'll have to jack up the front of the vehicle and safely support it on jackstands, the crankshaft sensor is located behind behind the crankshaft sensor on the bottom of the serpentine belt. The Belt has to come off, then the crankshaft pulley has to come off, in order to get at the sensor.



Because they may involve removing part of the air conditioning system to get to it, a seriously suggest seeing a mechanic so have the A/C system professional discharged, before continuing.
