how to pour coolant into car

That little gauge on your dashboard showing your engine temperature might not get much attention until it starts creeping into the red. An overheated engine is a serious problem, and one of the simplest ways to prevent it is by ensuring your car has the right amount of coolant. Knowing how to pour coolant into car is an essential piece of maintenance that can save you from a costly repair and a long day on the side of the road.

Getting Ready to Add Coolant

Before you open anything, your car’s engine must be completely cool. Opening a hot radiator cap is extremely dangerous, as the pressurized system can spray scalding coolant. While you wait, check your owner’s manual. It will tell you the specific type of coolant your car needs. Using the wrong kind can damage your engine over time. You’ll also want to locate the coolant reservoir—it’s usually a translucent plastic tank with “MIN” and “MAX” lines on the side.

The Simple Steps for How to Pour Coolant into Car

Once the engine is cool, you’re ready to begin. Find the coolant reservoir and check the fluid level against the “MIN” and “MAX” lines. If it’s low, this is where you’ll add more coolant. Slowly pour the recommended coolant into the reservoir until the fluid level reaches the “MAX” line. Be careful not to overfill it. If you need to open the radiator itself (only if the reservoir is empty), ensure the engine is cool, place a thick cloth over the cap, and turn it slowly to release any remaining pressure before fully removing it.

Important Tips for a Smooth Process

Always use a pre-mixed coolant, or if you use concentrate, mix it 50/50 with distilled water. Tap water contains minerals that can form deposits inside your cooling system. Never pour cold coolant into a hot engine, as the sudden temperature change can cause cracks. After you’ve added coolant, securely close the caps. It’s a good idea to start the engine and let it run for a few minutes, allowing the new coolant to circulate. Recheck the reservoir level after the engine cools down again and top it off if needed.

Keeping an eye on your coolant level is a simple habit that pays off. By performing this quick check every few weeks, you can help ensure your engine runs at the right temperature for years to come.
