Caution: Under pressure, the boiling point of the coolant in the radiator can be significantly 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 cooling mixture will splash onto the engine, the fenders of the car and the person who removed the radiator cap, which can result in serious 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.
- Also, the quality of water plays an important role in the cooling liquid solution. Drinking water from the tap usually meets the requirements quite well. The quality of regenerated sea water does not meet the necessary conditions.
- Using the wrong type of antifreeze can cause irreparable damage to your engine.
- If the radiator, cylinder head or cylinder head gasket is replaced, the old coolant must not be used and must be replaced with fresh coolant.
