That little dashboard light shaped like a tiny thermometer or the sight of a puddle of brightly colored liquid under your car can cause a moment of panic. Don’t worry! Your cooling system is just asking for a drink. Keeping your car’s antifreeze, also called coolant, at the right level is one of the easiest and most important bits of maintenance you can do. It protects your engine from freezing in winter, overheating in summer, and corrosion year-round. Knowing how to add antifreeze to car systems is a simple skill that can save you from a costly repair.
Getting Ready to Add Coolant
First, you need the right stuff. Check your owner’s manual to see what type of antifreeze your car requires; using the wrong kind can cause damage. Always work on a cool engine to avoid being burned by hot coolant or steam. Pop the hood and locate the coolant reservoir—it’s usually a translucent plastic tank with “Full” and “Low” marks on the side. This is where you’ll be adding the fluid.
The Simple Steps for How to Add Antifreeze to Car
Once the engine is completely cool, unscrew the cap on the coolant reservoir. Check the fluid level against the “Full” and “Low” marks. If it’s below the “Low” line, it’s time to top it off. Slowly pour your antifreeze into the reservoir until the level reaches the “Full” mark. Be careful not to overfill it. Screw the cap back on tightly, and you’re almost done.
A Few Important Tips to Remember
Never open the radiator cap when the engine is hot. The cooling system is under extreme pressure, and opening it can release scalding fluid. If you need to add a significant amount of coolant frequently, this could be a sign of a leak, and it’s a good idea to have a mechanic take a look. Also, always clean up any spills, as antifreeze is sweet and toxic to animals.
And that’s all there is to it! By taking just a few minutes for this simple check, you’re helping to ensure your engine runs smoothly and stays protected through every season. It’s a small task with a big payoff for your car’s health.
