Temperature sensor for the radiator fan overrun and fuel pump overrun.
The thermo switch controls the fan and fuel pump run-on (prevention of vapour bubbles). The original switch has a switch-on temperature of 110°. This means that a clear build-up of heat must first form, which puts a lot of stress on the components. The transmitter offered here switches on the aftertreatment hose of the fan and fuel pump already at 100°.
Switching point: 100° C
Replaces the original part no. 535 919 521.
