2. The position of the coolant temperature sensor and thermal switch depends on the type of engine, but usually it looks like this.
Engine 1.1 and 1.3
3. Thermal switch: located in the center tube between the drive manifold and the thermostat housing. Controls the preheater in the drive manifold. When the liquid warms up to a temperature of 35°C, the switch turns off the heater.
4. Temperature sensor: located in the thermostat housing 3 (pic. 2.4).
Pic. 2.4. Cooling system - engines 1.1 and 1.3 l
1 - thermal switch 2 - gasket; 3 - thermostat housing; 4 - gasket; 5 - thermostat; 6 - cover gasket; 7 - thermostat cover; 8 - radiator; 9 - water pump gasket; 10 - water pump; 11 - manifold outlet fitting; 12 - metal tube; 13 - elastic pipe; 14 branch pipe of the thermostat housing / head; A - entrance to the metal tube from the lower radiator pipe; B - entrance to the metal tube from the stove; C - exit from the thermostat housing; D - outlet from the thermostat to the radiator; E - entrance to the metal tube from the drive manifold; F - outlet from the thermostat housing to the drive manifold
Engine 1.6 and 1.8 carburetor
5. Temperature sensor: located in the outlet fitting from the head, above the flywheel.
6. Thermal switch: located on the top surface of the coolant tee. This tee is screwed to the engine head on the spark plug side. The switch is used to control the on and off of the mixture heater in the drive manifold.
7. Thermal switch: housed in a tee body screwed to the engine head on the spark plug side. This switch is used to control the damper on automatic starting equipment, 1.8 engine with fuel injection.
8. Temperature sensor: located in a tee screwed to the engine head from the side of the spark plugs. The sensor is screwed in from below or from above, depending on the type of tee.
9. Thermal switch: located on the upper surface of the tee screwed to the engine head from the side of the spark plugs.
Engine 1.6D (diesel)
10. Temperature sensor: located in the side wall of the tee screwed to the engine head from the side of the injectors.
11. Heater sensor: located in a fitting screwed to the head above the flywheel. At temperatures above 35°C, it cuts off the voltage from the heaters.
All types of engines
12. Disconnect the wiring from this temperature sensor or thermal switch.
13. Unscrew and remove the sensor or switch and plug the hole with a plug prepared in advance.
14. During installation, it is necessary to pay attention that when tightening with a torque of 10 Nm, the key does not break off, which can damage the switch or sensor. Check and, if necessary, add fluid to the cooling system.
