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.
Sensor (2, fig. 5.194) coolant temperature indicator is installed on the front cooling pipe. Disconnect loop (1) away from the sensor, unscrew it. Collect the leaked coolant and send it for recycling.
The installation of the temperature sensor should be carried out in the reverse order, while it is necessary to replace the sealing ring of the sensor. Return the temperature sensor and tighten it to 13 Nm (1.3 kgf·m).
Check coolant level and top up if necessary. Bleed the cooling system. Remove air from the cooling system and check it for leaks.
Read information from the fault memory of the ECU-KSUD system «DME». Check the recorded error messages and rectify them. Erase fault memory.
