Attention. Under pressure, the boiling point of the coolant in the radiator can be much higher than at normal atmospheric pressure. Removing the radiator cap on a hot engine (at high pressure), can cause the liquid to boil instantly with an explosive effect. The coolant mixture will splash onto the engine, vehicle fenders, and the person who removed the radiator cap, resulting in severe burns.
Note.
- Use only GM coolant with a composition of 50% water and 50% antifreeze. Antifreeze not only prevents the cooling system from freezing, but also protects all components that come into contact with the coolant from rust and scale. In this regard, antifreeze must be added to the coolant even when operating the car in countries with a tropical climate.
- Water quality also plays an important role in the coolant solution. Drinking water from a tap is usually adequate. The quality of the reclaimed sea water does not meet the required conditions.
- If the wrong type of antifreeze is used, irreparable damage can be caused to the engine.
- If the radiator, cylinder head or cylinder head seal is replaced, the old coolant must not be used - it must be replaced with fresh.
