Straight from my service manual
Crankshaft Position (CKP) sensor is located on front cover near crankshaft pulley.

  1. Disconnect negative battery cable.
  2. Raise and support vehicle.
  3. Disconnect CKP sensor connector.
  4. Remove CKP sensor bolts and CKP sensor.
  5. To install, reverse removal procedure.
  6. Tighten CKP sensor bolts to 62 in-lbs

    NOTE:Before proceeding, rotate crankshaft until cylinder No. 1 is at Top Dead Center (TDC) of compression stroke and TDC mark lines up with timing mark.

    1. Disconnect negative battery cable.

    2. Note position of CMP sensor electrical connector.

    3. Remove CMP sensor.

    4. Apply reference marks on camshaft synchronizer assembly and engine.

    5. Remove camshaft synchronizer assembly hold-down bolt and clamp.

    6. Remove camshaft synchronizer assembly.

    7. Oil pump drive shaft may come out with synchronizer. If so, retrieve oil pump driveshaft before proceeding.
    To install...
    Install Synchro Positioner (303-589) on camshaft synchronizer assembly (CMP sensor removed).

    Turn camshaft synchronizer shaft clockwise until tool boss engages with notch in camshaft synchronizer assembly. Tool should fit squarely in top of camshaft synchronizer assembly.

    NOTE:Coat camshaft synchronizer gear with engine oil prior to installation. Failure to do so, may result in gear failure.

    Ensure piston No. 1 is in TDC position on compression stroke. Install oil pump drive shaft in camshaft synchronizer assembly.
    Lubricate camshaft synchronizer gear with engine oil.

    NOTE:During installation, arrow on synchro positioner will rotate clockwise until oil pump intermediate shaft and camshaft gear engage.

    Insert camshaft synchronizer assembly into engine. When camshaft synchronizer is installed into engine, synchro positioner should point 38 degrees from centerline of engine.
    If arrow on synchro positioner is not pointing 38 degrees from centerline of engine, remove camshaft synchronizer assembly and return to step 2. If camshaft synchronizer is pointing 38 degrees from centerline of engine, remove synchro positioner and go to next step.
    Install camshaft synchronizer hold-down clamp bolt and tighten to specification. Install CMP sensor and tighten bolts to specification.
    Connect CMP sensor harness connector and negative battery cable.

Where is the cam shaft senser on a ford ranger 2.5 td 2002

Ford did not put a 2.5 in a Ranger, maybe a 2.3 ?
2.3 = 2007-01-27_154722_2.gif
3.0 - The CMP sensor& synchronizer/shaft are located behind the intake manifold (i.e., back near the firewall on a Ranger) on the top of the cylinder block. If you just need to replace the sensor, it is a simple job of unplugging the electrical connector and removing the screws holding the sensor in place. Here is a sketch of the sensor to give you an idea what to look for:

2001 ford ranger 3.0 auto trans swap out with a 2002 auto trans

On Chevy transmissions there is, on the input shaft, there are two (2) little tabs at the 12 and 6 O'clock position or 180 degrees from one another. When installing the transmission these can often break leaving the transmission useless. It will need to be taken apart and checked on. If it is broken then you can easily replace it from a junkyard trans. (just look forward to a day in the yard tearing apart a transmission) and replace it accordingly.
Keep in mind when reinstaling the replaced transmission, that you HAVE to line these up by spinning the Torque Converter untill it slips on easily. otherwise it will just break again.

Ford ranger 2002 6 4.0 LTR truck over heating.

The water is from the thermostat housing, fairly common leak. The ticking maybe from the timing chain cassette. You may have already had the cam timing slip (the cam gears are not keyed, they are held in place by torque alone. The oil gauge sounds like an electrical problem (either sender or sender wiring).
