What happens when there is air in the car radiator?
1 Answers
The presence of air in the car radiator essentially means there is an airlock in the coolant, which can hinder the smooth circulation of the coolant. Below are some precautions regarding the use of a car radiator: 1. Always use dedicated radiator fluid or qualified antifreeze: When selecting radiator fluid or antifreeze, opt for high-quality, diluted radiator fluid or antifreeze. In case of an emergency shortage, you can supplement with tap water to prevent unnecessary losses due to lack of coolant. Additionally, dedicated radiator fluid and antifreeze offer freeze and boil protection, which water cannot match. 2. Do not overfill the car radiator: If adding water, avoid filling it too much or completely, as this can lead to significant overflow due to thermal expansion, leaving behind water stains and scale deposits on the surface. Moreover, adding water can cause scale buildup in the cooling system, clogging pipes, impairing heat dissipation, and damaging the engine. 3. The fluid level in the car radiator should be maintained between the min and max marks: If it falls below the min mark, it is necessary to add the same brand and specification of coolant, or replace the entire coolant. The choice of coolant primarily depends on the local minimum temperature, and the factory-fill is typically all-season type.
