What is coolant?

Engine coolant is a formulation of chemicals that help protect your car’s engine components from corrosion and cavities. Coolant is essential for providing an effective heat exchange medium which removes excess heat from the engine.

What you’ll need

For the purpose of safety, it’s best to use a glove and rag before looking under the hood. Using these will protect your hands from contact with any hot components such as the radiator cap.

How to check your coolant levels

1. Check your car is safe for inspection

Before checking your car, it’s vital to ensure the engine has cooled down. A hot engine could mean there is pressure in the cooling system and if opened, could result in hot liquid spurting out and causing serious injury. Lifting the hood can aid in letting heat escape and speed up the cooling down process.

2. Locating your car’s cooling system

When it’s safe to inspect your car, you’ll need to locate the coolant reservoir. If you’re having trouble locating the reservoir, then it’s best to refer to your car manual which will detail exactly where it is. Some vehicles may not have a reservoir. In this case, you’ll need to locate a cap that’s on top of the radiator.

3. Identify coolant levels

On the side of the reservoir, you’ll find markings that indicate when it is “low” or “full”. Because the reservoir is translucent, it should be easy to identify the level inside. If the coolant level is sitting close to or below the low mark, you’ll need to add more coolant. If your vehicle doesn’t have a reservoir, you’ll need to open the cap on top of the radiator and identify if the coolant level is low before adding more.

How often should I check my car’s coolant levels?

It’s a good idea to check coolant levels at least every three weeks or before a long trip. If you notice the temperature indicator in your car continuously displays high temperatures, then this could be a warning sign that your car is overheating from a lack of coolant.

Troubleshooting advice

If you find you have to top off your coolant frequently, this could indicate your car is leaking coolant. If this is the case, you need to have a specialist at Natrad inspect your cooling system.
