Vehicles after change point in 1982 REMOVING AND INSTALLING/CHECKING COOLANT TEMPERATURE SENSOR The temperature sensor measures the engine temperautre and sends this information as a resistance value to the control unit. The resistance value drops with rising temperature (NTC). 1 = Plug connection 2 = Housing 3 = NTC resistor | |
Removing and Installing: Pull off plug (1). Unscrew temperature sensor. Installation: Tightening torque*. * See Specifications | |
Installation: Check code number (1)*. Replace seal (2). FD = Manufacturing date Fill and bleed cooling system - see Group 17. * See Specifications | |
Testing: Connect Jetronic test leads 61 1 440. Check nominal value* with an ohmmeter. Testing Entire Temperature Range: Remove temperature sensor, heat to testing temperature in a water bath and check resistance* with an ohmmeter. * See Specifications |
