How to Check the Coolant Level?
2 Answers
To check the coolant level, observe the MIN (minimum) and MAX (maximum) markings on the car's radiator. The coolant level should be maintained between the MAX and MIN marks, indicating the correct level. The coolant should neither be too much nor too little. If the level is below MIN, it indicates insufficient coolant, which needs to be replenished promptly. The full name of coolant should be antifreeze coolant, meaning it has antifreeze properties. Antifreeze prevents the coolant from freezing during cold seasons, which could otherwise crack the radiator or damage the engine block. Antifreeze is not only for winter use but should be used year-round. In regular car maintenance, the engine antifreeze should be replaced every year.
With over two decades of driving experience, I've accumulated considerable expertise in checking coolant. Locate the translucent plastic reservoir in the engine bay marked with MIN and MAX level indicators—it's as simple as checking water levels. Remember to always inspect when the engine is cold, such as before starting in the morning or after waiting half an hour post-shutdown, to avoid burns from opening a hot system. The ideal fluid level should be between the two marks; if it's low, it's time for a top-up. Use dedicated coolant when refilling—never tap or river water, as this dilutes the antifreeze and compromises cooling efficiency. Regular checks are crucial; I've made it a monthly habit to glance at it, preventing potential engine overheating during long trips. Extra vigilance is needed in winter—insufficient coolant levels risk radiator freeze damage, which is costly to repair.
