How To Check Coolant Level in Car Radiator

Engine overheat is the last thing you want to happen if you're on your way to a job interview or if you're on a road trip. However, there are several ways on how you could prevent your car's engine from overheating. One of the things you could do is to regularly check your car's coolant reservoir. The other thing you could do is to check the car radiator to see if it has enough coolant or water to prevent the engine from overheating.

Your car's engine generates heat as you drive, which will overheat if your car's cooling system, such as the radiator, doesn't have enough coolant. As what we've previously said, the engine coolant is responsible for keeping your car's engine at an optimal running temperature.

The engine coolant is a mixture of distilled water and antifreeze and it comes in several colors such as green, yellow, pink, red, or orange. It is ideal to check your car's radiator before you set off and drive. Checking your car's radiator is simple and easy, which is similar to inspecting the coolant level in your car's reservoir. The first thing you need to do is to make sure that your car's engine is not hot before you open the hood to check the radiator. The reason behind this is that if you open the radiator cap while the engine is hot, the pressure generated by the engine's hot temperature will come out, which could cause serious burn.

The next thing you need to do after ensuring that your car's engine is not hot is to open the radiator cap and turn it counterclockwise. Then, look into the radiator hole to check if there's enough coolant or liquid inside. An indication that your car's radiator has enough coolant is when the liquid is just below the cap and it covers the radiator tube. If you can't see any liquid, then you should add coolant accordingly.

You can also add a 50-50 mixture of water and coolant into the radiator. After adding and ensuring that your car's radiator has enough coolant, place the cap and close it by turning it clockwise. It's that easy. Regularly check your car's radiator to prevent the engine from overheating. If you own an older car, it is ideal to check it before you set off and drive.

Engine overheat is a hassle but, with simple regular maintenance such as checking the radiator could prevent it from happening.
