What is the normal consumption of coolant?
2 Answers
Coolant consumption of about ten to thirty-six percent is normal. The methods to check for insufficient coolant are: 1. Start the vehicle, the vehicle system will self-check, check the vehicle dashboard, there will be a fluid level prompt on it; 2. Pull the handle inside the driver's seat to open the hood, open the hood, and check the coolant reservoir, which is marked with high and low values. Coolant refers to a liquid containing special additives, mainly used in liquid-cooled engine cooling systems. The precautions for its use include: 1. Different types of antifreeze cannot be mixed; 2. Do not open the reservoir cap or drain valve immediately after the car has been driven; 3. When replacing the coolant, all the old antifreeze must be removed and the reservoir thoroughly cleaned.
Coolant consumption should be very low under normal circumstances, with almost no visible reduction. Based on my experience, if the level drops less than half a cup (approximately 50ml) every one or two months of driving, it falls within a reasonable range. This is primarily because the cooling system is designed to be closed, but minor evaporation naturally occurs, especially during high summer temperatures or long-distance driving. Think about it—coolant doesn't just prevent freezing; it also helps the engine dissipate heat efficiently. If consumption is too rapid, such as needing a top-up every week, it might indicate minor leaks in the pipes or a seal issue with the water pump. I've seen many car owners overlook this, leading to engine overheating and costly repairs. Therefore, make it a habit to check the coolant level monthly when the engine is cold, observing the position between the MIN and MAX lines on the expansion tank. If the level consistently drops quickly, it's best to have a professional shop check for potential faults. During routine maintenance, have a technician inspect the cooling system's sealing to significantly prevent unexpected consumption.
