What does low coolant mean?

[ReaganLynn]

Low coolant means that the engine coolant is below the normal liquid level and needs to be checked for any shortage. The inspection methods mainly include: 1. Open the engine cover to check the coolant level in the auxiliary water tank. If the coolant level is below the minimum limit, it is necessary to add coolant in time. 2. There may also be problems elsewhere in the cooling system, such as thermostat failure, radiator fan failure, etc. Extended content: 1. The thermostat is generally installed at the outlet of the radiator and the inlet of the water pump. 2. The thermostat is a component that automatically acts as a valve based on the engine water temperature. When the coolant temperature is low, the thermostat blocks the low-temperature coolant from the radiator, preventing it from entering the engine water jacket, allowing the water temperature in the jacket to rise quickly.
