Where to Add Engine Coolant?

Engine coolant is added to the coolant reservoir, which is located in the engine compartment. You can see it by opening the engine hood. The full name of coolant should be antifreeze coolant, meaning it has antifreeze properties to prevent the coolant from freezing and expanding in cold seasons, which could crack the radiator or damage the engine cylinder block. The main function of coolant is to protect the engine for normal and optimal operation, circulating within the engine radiator to provide antifreeze, anti-boil, anti-rust, and anti-corrosion effects. Most antifreeze liquids are colored red or green to make it easier to observe leaks or to distinguish them from other engine fluids, avoiding confusion.

As someone who has driven for many years, I always add coolant to the plastic expansion tank in the engine compartment, which is usually clearly marked with 'COOLANT' or a coolant label, and the cap is an easily recognizable point. Before adding, you must wait for the car to cool down for at least half an hour, otherwise the hot steam can scald your hands. Then open the cap and slowly pour in the recommended coolant using a funnel, making sure not to exceed the MAX line—because it will overflow due to thermal expansion and contraction. I recommend using pre-mixed coolant to avoid the hassle of mixing it yourself, maintaining a 50% coolant and 50% distilled water ratio. Regularly checking the fluid level is crucial; I take a quick look every month to ensure it stays between the MIN and MAX lines. A significant deviation might indicate a system leak or aging. Safety first—wear gloves to avoid contact with antifreeze components.

If it's your first time adding coolant, don't be nervous. Just open the hood and look for the transparent or semi-transparent plastic container near the engine, which is labeled 'coolant' or similar. Remember to wait until the engine has completely cooled down after turning off the car to avoid accidental injuries. Slowly pour the purchased dedicated coolant to just below the MAX line, making sure not to fill it completely—leave some space. I learned this by reading the car manual multiple times; it includes diagrams to help locate the parts. After adding, wipe around the cap to prevent dirt from falling in and affecting the system. Regularly checking the fluid level before driving is simple yet practical, helping to prevent engine overheating issues. Just buy blue or green universal coolant and don't mix up the colors.

The coolant filling location is at the expansion tank in the engine bay, usually marked as COOLANT, with a screw-type cap. Every time I perform vehicle maintenance, I ensure the cooling system is cooled down first, then add the specified ratio of coolant without exceeding the MAX line. Regularly checking the fluid level is a habitual practice to prevent overheating failures due to insufficient cooling. Using the correct coolant mixture is crucial to avoid corrosion issues.

In my car repair experience, adding coolant must be done by locating the expansion tank cap in the engine bay – look for the COOLANT labeled position. Always ensure the engine is cool before opening the cap to prevent safety hazards. Slowly pour premixed coolant up to the MAX line, leaving room for expansion – never fill to the brim. Using the correct brand avoids chemical reactions, and regularly monitoring fluid levels helps extend engine life and reduce repair headaches.
