How to Add Car Coolant?

[LeChristian]

Correct steps for adding car coolant are: 1. Open the drain valve of the radiator, wait until all the antifreeze inside is drained, then use a properly sized tube to insert into the radiator and flush it with clean water, ensuring the water flows through the entire cooling system; 2. After completing the above steps, close the drain outlet and start adding coolant into the radiator until it is full, but do not exceed the marked line; 3. Start the engine with the radiator cap open, keeping the engine idling for two to three minutes to expel some air from the radiator. If the coolant level starts to drop, continue adding coolant until it reaches the marked line.

Be careful when adding coolant. Over the years running my auto repair shop, I've seen too many beginners getting scalded, so I emphasize that the car must be completely cooled down before starting. After the engine temperature drops, open the hood and locate the transparent coolant reservoir, usually at the front right, marked with a COOLANT label. Check the fluid level between the MIN and MAX lines—add if it's below MIN. Use the same type of coolant; avoid mixing brands randomly to prevent chemical reactions that could damage the engine. If unsure about the type, opt for pre-mixed universal coolant for safety. Pour slowly to avoid spilling onto engine parts and causing corrosion. After filling, tighten the cap securely, start the engine to warm up, and let the fluid circulate to release air bubbles. Drive for a few minutes and check if the level stabilizes—top up if it drops. This maintenance not only prevents overheating but also extends the radiator's lifespan. Check the level monthly to avoid costly repairs later.

Adding coolant is actually a basic task. I enjoy tinkering with my car and always find it fun. After the engine has completely cooled down, pop open the hood and easily locate the coolant reservoir—its position is obvious, so no need to panic. If the fluid level is low, just add coolant. I prefer using universal brands to avoid compatibility issues. Take your time when adding it—pour it slowly into the reservoir to prevent spills and air bubbles. Once done, start the engine and check if the fan operates to ensure the system is functioning properly. DIY maintenance is truly worthwhile—it saves repair costs and helps you understand your car's structure. Take the opportunity to inspect hoses for leaks or aging, and regularly replacing the fluid can make the engine more durable. Improved cooling efficiency also gives peace of mind on long trips. Before getting started, wash your hands, wear gloves, and have all tools ready—it's both eco-friendly and professional.

As a family daily driver, I prefer a simple approach to coolant maintenance. Always start when the car is completely cooled to prevent risks. Locate the coolant reservoir in the engine bay, and if the level is below MIN, top it up with the same type of fluid. I use eco-friendly green coolant for less pollution. Add slowly without exceeding the MAX line, then tighten the cap and run the engine for a few minutes to test. Regular checks prevent roadside breakdowns, ensuring safe school runs for the kids. No professional tools needed—saves money and hassle.
