how to add engine coolant to car

That little temperature gauge on your dashboard is one you never want to see creeping into the red. Your car’s cooling system works tirelessly to prevent that, and engine coolant is its lifeblood. If you’ve noticed your engine running hotter than usual or spotted a puddle of brightly colored liquid under your car, it might be time for a top-up. Knowing how to add engine coolant to car is a simple yet vital piece of maintenance that can save you from a roadside breakdown and costly repairs.

Getting Ready to Add Coolant

Before you begin, the most important step is safety. Never open the cooling system when the engine is hot. The system is under extreme pressure, and hot coolant can erupt, causing severe burns. Let the engine cool completely. While you wait, check your owner’s manual to confirm the type of coolant your car needs. Using the wrong kind can damage the engine. You’ll also want to have a funnel and some rags handy to keep things clean.

A Simple Guide on How to Add Engine Coolant to Your Car

Once the engine is cool, locate the coolant reservoir. It’s a translucent plastic tank, usually labeled and connected to the radiator. You’ll see “Full” and “Low” marks on the side. If the coolant level is at or below the “Low” line, it’s time to add more. Slowly unscrew the cap (never the radiator cap itself). Place your funnel in the opening and carefully pour the recommended coolant into the reservoir until it reaches the “Full” line. Avoid overfilling. Once done, securely screw the cap back on.

Choosing the Right Coolant for Your Vehicle

Coolant isn’t a one-size-fits-all product. It comes in different colors and formulas, like orange Dex-Cool or green ethylene glycol. Your car’s manufacturer specifies which type is best for your engine to prevent corrosion and ensure optimal performance. Mixing different types can cause them to gel and clog your cooling system. If you’re unsure, your owner’s manual is the best guide, or you can ask for help at an auto parts store.

When to Be Concerned About Low Coolant

Topping off your coolant every now and then is normal, but if you find yourself doing it frequently, it points to a larger issue. A consistent drop in coolant level often means there’s a leak in the system. This could be from a loose hose, a faulty water pump, or a cracked reservoir. If you suspect a leak, it’s a good idea to have a professional mechanic inspect your car to find and fix the source of the problem.

Keeping an eye on your coolant level is a small habit that pays off immensely. This simple check helps ensure your engine stays at a healthy temperature, protecting it from damage and keeping your drives smooth and worry-free for miles to come.
