Pic. 153. Scheme of switching on the electric motor of the fan of the engine cooling system: 1 - electric motor; 2 - sensor for turning on the electric motor; 3 - mounting block (fragment); 4 - ignition switch (fragment); 5 - relay for turning on the fan motor
Auxiliary relay 113.3747 is installed in the mounting block. Its characteristics are given in sec. «Lighting and light signaling». Electric motors are maintenance-free and should be replaced with new ones in case of failure. Brief technical characteristics of the electric motor:
- Rated shaft rotation frequency when the electric motor is loaded with an impeller, rpm - 2600±200
- Consumed current at the specified load and speed, A, no more than — 14
