How to Check if the Car Radiator Coolant is Low

[LaIvan]

Method to check the car radiator coolant level: Inspect the positions of the MIN and MAX markings on the car radiator. The coolant level should be maintained between the MAX and MIN marks for optimal operation, indicating neither too much nor too little. If the level is below MIN, it indicates insufficient coolant, and it needs to be replenished. When adding coolant, it is recommended to use specialized coolant. In emergency situations, distilled water can be used temporarily. However, before winter arrives, any coolant mixed with distilled water must be completely replaced. Tap water or other water sources should be avoided as the minerals and impurities they contain can form scale inside the cooling system under prolonged high temperatures and may also cause rust in the radiator and pipes, obstructing coolant flow. Therefore, these should only be used as a last resort.
