What Happens If a Car Runs Without Coolant for a Long Time?

Running a car without coolant for an extended period can lead to the formation of scale in the engine's water passages, potentially clogging them. Prolonged failure to replace the coolant may also cause its freezing point to rise and boiling point to drop, adversely affecting the engine's normal operation. Therefore, it is recommended to change the coolant regularly. Coolant is an essential fluid in the engine's cooling system, and neglecting its replacement can disrupt the proper functioning of the system. For regular household vehicles, it is advisable to replace the coolant every two years, and this should be done by professionals at specialized facilities. When purchasing coolant, always check the product specifications to ensure it is suitable for your vehicle. If the engine is running low on coolant during regular use, it is crucial to replenish it immediately.
