That little overflow tank under your hood plays a bigger role than you might think. Coolant, often called antifreeze, is the lifeblood of your car’s cooling system, working tirelessly to prevent your engine from freezing in winter, overheating in summer, and corroding year-round. Knowing how to pour antifreeze in your car is a simple yet vital piece of maintenance that can save you from costly repairs down the line.
Getting Ready to Add Coolant
Before you begin, safety is key. Never open the cooling system when the engine is hot, as it is under extreme pressure and can release scalding fluid. Always let the engine cool completely. You’ll also want to check your owner’s manual to confirm the specific type of coolant your car requires. Using the wrong kind can cause damage. Have a funnel, some rags, and, of course, the correct antifreeze ready to go.
A Simple Guide on How to Pour Antifreeze in Your Car
Locate the coolant overflow or reservoir tank; it’s usually a translucent plastic container with “Full” and “Low” marks on the side. Slowly unscrew the cap. If the coolant level is below the “Low” mark, it’s time for a top-up. Place your funnel in the opening and carefully pour the antifreeze in until the fluid level reaches the “Full” line. Avoid overfilling, as the liquid needs space to expand when it heats up. Once done, securely screw the cap back on and wipe up any spills.
Choosing the Right Coolant for Your Vehicle
Not all antifreeze is created equal. They come in different colors and chemical formulas, such as IAT, OAT, and HOAT, each designed for specific engine types and materials. Pouring in the incorrect coolant can lead to gel formation or corrosion, which can clog and damage your radiator and heater core. Your vehicle’s owner’s manual is the best resource for identifying the right product, ensuring compatibility and optimal performance.
When to Seek Professional Help
While topping off your coolant is a straightforward task, there are signs that point to a larger issue. If you find yourself adding antifreeze frequently, that indicates a potential leak in the system. Notice a sweet smell inside the car or see white, sweet-smelling smoke from the exhaust? These are red flags for a leaky heater core or a blown head gasket, respectively. In these cases, it’s best to have a trusted mechanic inspect your vehicle.
Keeping an eye on your coolant level is a simple habit that pays off. By performing this quick check every few weeks and topping it off when needed, you’re taking a proactive step in protecting your engine and ensuring many more miles of reliable driving.
