how to put coolant into a car

That little temperature gauge on your dashboard is one you never want to see creeping into the red. When your engine starts running hotter than it should, it’s often a sign that your coolant level is low. Coolant, also known as antifreeze, is the lifeblood of your car’s cooling system, circulating through the engine to absorb and dissipate heat. Knowing how to put coolant into a car is a simple yet vital piece of knowledge that can prevent a roadside breakdown and costly engine damage.

Getting Ready to Add Coolant

Before you start, safety is key. Never open the radiator cap when the engine is hot. The system is under extreme pressure, and hot coolant can erupt, causing severe burns. Always let the engine cool down completely. You’ll also need to gather your supplies: a funnel and the correct type of coolant for your vehicle. Check your owner’s manual to see what your car requires, as using the wrong type can harm the cooling system.

A Simple Guide on How to Put Coolant into a Car

Once the engine is cool, locate the coolant reservoir. It’s usually a translucent plastic tank with “MIN” and “MAX” level marks on the side. You can typically see the coolant level without opening the cap. If the level is below the “MIN” line, it’s time to top it up. Slowly twist off the reservoir cap. Place your funnel in the opening and carefully pour the coolant in until it reaches the “MAX” line. Avoid overfilling. Securely replace the cap, and you’re done!

When to Check Your Coolant Level

It’s a good habit to check your coolant level every time you pop the hood for an oil change or when you’re filling up your windshield washer fluid. Regular checks help you spot a slow leak early. If you find yourself needing to add coolant frequently, that’s a sign of a potential leak or another issue that a mechanic should investigate.

A Note on the Radiator Cap

In most modern cars, you will only ever add coolant to the reservoir. However, if your car does not have a reservoir, or if a mechanic has instructed you to, you may need to add it directly to the radiator. The same safety rule applies: the engine must be completely cool before you even think about touching the radiator cap.

Keeping your car’s coolant at the proper level is a quick and easy task that pays off in the long run. By taking a few minutes for this simple maintenance, you’re helping to ensure your engine runs at a safe temperature, protecting your vehicle for many miles to come.
