- disconnect a shtekerny chetyrekhshtyrkovy block (fig. 196) of the temperature sensor of turning on of the fan from the thermostat case;

Fig. 197. Check of the temperature sensor for turning on of the fan of system of cooling after a stop of the engine and the water pump: «1», «2», «3» and «4» — contacts





- connect by means of a piece of a wire contacts «1» and «3» (a brown-red cable and a fulvous cable) (fig. 197) ;
- thus should earn the fan of system of cooling and the circulating pump of cooling liquid;
- if the fan and the circulating pump did not earn, then there are other malfunctions which should be revealed on HUNDRED Volkswagens by means of the corresponding measuring equipment.
