MBE 900 ENGINE COOLANT TEMPERATURE SENSOR

The Engine Coolant Temperature Sensor is located on the left-hand side of the front connector housing, just below the lifting eye. ‪

Engine Coolant Temperature Sensor Removal

Remove the Coolant Temperature Sensor as follows: ‪

PERSONAL INJURY

To avoid injury from scalding, drain the radiator when the engine and coolant are cool.

Note: The following instructions apply to the four-cylinder as well as the six-cylinder engine.

  1. Drain the coolant from the engine.
  2. Remove the hose clamp attaching the (surge tank) coolant delivery hose to the front connector housing. See Figure 43251 .

    Note: Collect any coolant that runs out of the hose.

    Engine Coolant Temperature Sensor Removal / Installation

  3. Disconnect the wiring harness that runs to the coolant temperature sensor.
    1. Disconnect the electrical connector from the coolant temperature sensor located on the left-hand side of the front connector housing, just below the front lifting eye.
    2. Remove the clip that attaches the harness to mounting bracket for the crankcase breather hose.
  4. Remove the Engine Coolant Temperature Sensor from the connector housing.

Engine Coolant Temperature Sensor Installation

Install the Engine Coolant Temperature Sensor as follows: ‪

  1. Install a new Engine Coolant Temperature Sensor in the front connector housing.
  2. Connect the wiring harness that runs to the coolant temperature sensor.
    1. Connect the electrical connector to the coolant temperature sensor.
    2. Install the clip that attaches the harness to mounting bracket for the crankcase breather hose.
  3. Fill the engine with the removed coolant, and check for leaks and proper operation.
