Engine coolant

Engine coolant, or antifreeze, prevents your engine from overheating or freezing by regulating its temperature. It’s housed in the radiator and should be checked every month, especially before long trips.

Checking and topping up your coolant

Same with your engine oil, check the coolant reservoir when the engine is cold. Never open the radiator cap when the engine is hot, as the pressurised system can cause burns.

Your coolant reservoir should have markings to show low and full levels, some may even be translucent so you can see its level from the outside. If the coolant is low, refill it with the right kind of coolant for your car.

Transmission fluid

Transmission fluid lubricates and cools the components of your car's automatic transmission system, enabling seamless gear changes. Unlike engine oil, transmission fluid doesn’t need frequent checks – once every six months is usually enough.

Checking your transmission fluid level

For automatic cars, check the fluid using the transmission dipstick, typically located near the back of the engine bay. The process may vary between different models, so it’s best to refer to your owner’s manual. If your transmission fluid is low, it’s time for a trip to the mechanic’s. Manual cars will usually require a mechanic to check and refill as well.

Brake fluid

Brake fluid is a hydraulic fluid that transfers force from your brake pedal to the brake pads, for your car to stop efficiently and safely. This fluid should be checked at least every six months.

Checking your brake fluid level

The brake fluid reservoir is usually located near the back of the engine bay and marked clearly. If the fluid is low, you can top it up with the recommended type, but it’s worth checking out the reason for the drop with a mechanic, as it could mean a leak or worn brake pads.

Power steering fluid

Power steering fluid allows you to steer effortlessly by providing hydraulic assistance to the steering system. Without it, turning the wheel can become difficult, especially at low speeds. Check this fluid every three months, or anytime you’re getting under the hood to check anything else, really.

Checking and topping up your power steering fluid

The power steering fluid reservoir is usually marked with a steering wheel symbol. If the fluid is below the recommended level, top it up with the correct type. If you hear whining noises or experience stiffness while steering, it’s best to head to a mechanic.

Wiper fluid

Although it doesn’t affect your car’s mechanics, wiper fluid is crucial for maintaining visibility, especially in adverse weather conditions. Your wiper fluid does get used regularly on the road, so it does need to be refilled regularly once a month.

Checking and topping up your wiper fluid

This is an easy one. Simply locate the reservoir, often marked with a windshield symbol, and ensure it’s filled with wiper fluid or a mix of water and washer concentrate (check your manual). Low wiper fluid can be topped up easily at home, but if your wipers still struggle to clean effectively, check for blockages or replace the blades.

Blinker fluid

Last but not least – just kidding, it doesn’t exist!

Regularly checking and maintaining your car’s fluids is a simple yet effective way to keep your vehicle in excellent condition. By taking these small steps, you can ensure a smoother, safer driving experience and avoid unnecessary repairs down the road.
