Coolant level switch, location/task/design/function - GF54.30-P-4103GH
MODEL 163 as of 1.3.99
The coolant level indicator electronic switch (S41) is integrated in the coolant reservoir.
| Coolant level switch, task | To record the coolant level: Coolant level in order or below minimum |
| Coolant level switch, design | The coolant level indicator electronic switch (S41) consists of two electrodes which are permanently cast to the coolant reservoir and a connector with contacts which have an electrical connection to the electrodes. |
| Coolant level switch, function | The two electrodes are either immersed or not immersed in the coolant depending on the coolant level. As a result the test current changes via the coolant level indicator electronic switch (S41). This change is evaluated by the instrument cluster (A1). An alternating current is used so that the electrodes do not disintegrate. |
