Checking the tightness of the cooling system:
1. Check that the hoses leading to the radiator, engine and heater are tight.
2. Check the condition of flexible hoses by crushing them. If they are stiff, brittle or cracked, they must be replaced with new ones.
3. Check that the hoses are well seated on the connectors.
4. The screws of the cable clamps should be tightened. They may have become loose during driving and under the influence of pressure in the system. Replace corroded bands with new ones.
Checking and topping up the coolant level:
The coolant level should be between the MIN and MAX marks. A much higher or lower level indicates a system fault, the cause of which must be determined. If the engine is hot, carefully loosen the expansion tank cover by one turn. There is a danger of steam spraying out. For safety, unscrew the cover through the cloth.
1. Check the coolant level with the engine cold, because then there is no excess pressure in the system.
2. With the engine cold, the coolant level in the expansion tank should be between the MAX and MIN markings. remember, that the liquid level is always higher when the engine is hot. Do not be influenced by the possible indication above the MAX.
3. To refill the liquid, unscrew the tank cover. When the engine is hot, use a thick rag and unscrew the cover slowly and carefully to relieve pressure in the system.. Opening the lid too quickly will cause hot liquid to squirt out of the tank.
4. Never add liquid above the MAX level. The liquid expands at high temperature and its excess escapes to the outside of the system.
5. You can fill in small fluid losses with a cold or hot engine.
