he coolant in a car’s cooling system should not be filled to the very top. Overfilling the coolant reservoir can lead to problems, including potential damage to the cooling system or engine. Coolant expands as it heats up, so there needs to be some space left in the reservoir to accommodate this expansion.
Typically, there is a “MAX” and “MIN” or “FULL” and “LOW” marking on the coolant reservoir. You should fill the coolant to the level indicated by the “MAX” or “FULL” mark when the engine is cold. This allows for some expansion as the engine heats up. Do not fill it beyond the “MAX” or “FULL” mark.
It’s essential to check your car’s coolant level regularly, especially before long trips or during routine maintenance. Ensure that the coolant level is within the recommended range to help keep your engine operating at the correct temperature and prevent overheating.
If you’re unsure about how to check or add coolant, consult your car’s owner’s manual or seek the assistance of a qualified mechanic.
