Attention! Carry out work on a cold engine.
The replacement of the coolant temperature sensor must be carried out in the following order. Read information from the fault memory of the ECU-KSUD system «DME», switch off the ignition and remove the noise insulation cover.
coolant temperature sensor (2, fig. 4.136) installed on the front pipeline of the cooling system. Remove vacuum line (1) and disconnect the loop (2) from the temperature sensor. Unscrew the coolant temperature sensor, collect the leaked fluid and send it for disposal.
The installation of the temperature sensor should be carried out in the reverse order, while it is necessary to replace the sealing ring, screw in the temperature sensor and tighten it with a torque of 16 Nm (1.6 kgf·m).
Check coolant level and top up if necessary. Remove air from the cooling system and check it for leaks.
Read information from the fault memory of the ECU-KSUD system «DME». Check recorded fault messages and rectify faults. Erase fault memory.
