What does it mean to check the coolant level with the engine off?
1 Answers
The prompt to check the coolant level with the engine off indicates that the vehicle's antifreeze is low, and it is necessary to promptly inspect whether the antifreeze level is too low. If the level is too low, antifreeze should be added immediately. Only when the indicator light turns off can you continue driving. Coolant is essentially the engine's cooling water; you can add coolant, or if coolant is not available, water can be used temporarily. However, it's important to check for any leaks. If there is a leak, adding water should suffice temporarily, but ensure it's sufficient. Here is additional information: 1. Function of the cooling system: The purpose of the car's cooling system is to dissipate some of the heat absorbed by heated components in a timely manner, ensuring the engine operates at the most suitable temperature. Engine cooling systems can be either air-cooled or liquid-cooled. A system that uses air as the cooling medium is called an air-cooled system, while one that uses coolant as the medium is called a liquid-cooled system. 2. Components of the cooling system: The cooling system of a car engine is a forced-circulation liquid-cooled system, which uses a water pump to increase the pressure of the coolant, forcing it to circulate through the engine. The cooling system mainly consists of the water pump, radiator, cooling fan, expansion tank, thermostat, water jackets in the engine block and cylinder head, and other auxiliary components.
