General description of the cooling system (Skoda Favorit)

1. Hermetically sealed cooling system (pressure above atmospheric) includes a centrifugal water pump; aluminum cross flow radiator (equipped with plastic side tanks); transparent expansion tank mounted on the inner panel of the left wing; a temperature-controlled electric fan mounted on the back of the radiator; thermostat, as well as connecting pipes and hoses. The drain plug of the cooling system is located in the lower pipe (see photo). There is another drain plug - in the cylinder block, near the clutch housing on the fuel pump side.


2. The relative position of the system components and the direction of coolant circulation are shown in Fig. 3.1.

Warning: Do not remove the expansion tank filler cap or disconnect any parts of the cooling system until the engine has cooled down. This will cause hot steam and liquid to escape. If for any reason the cap does come off, carefully relieve the pressure in the system. To do this, wrap a thick cloth folded in several layers around the cap and slowly unscrew it until you hear a hissing sound. When the hissing stops (pressure released), slowly unscrew the cap and remove it: if the hissing noise starts again, stop and wait until it subsides. Keep your face away from the filler neck and protect your hands with gloves.

Warning: If antifreeze comes into contact with your skin or the painted surfaces of your vehicle, immediately wash away spilled drops with plenty of water. Never leave antifreeze in an open container or spilled on the garage floor - the deadly poisonous liquid can attract children and pets with its pleasant smell.

Warning: If the engine is hot, the fan may operate even if the ignition is off. When working in the engine compartment, be careful not to let your hands, hair, or clothing come into contact with the fan blades.
