Unsure of which fluid is leaking?

If you can identify the colour and the location of the leak, then it makes it easier to diagnose which fluid is causing the problem. A garage technician will be happy to help you diagnose your car leak.

Car leaking from the front or from under the engine

Engine oil

Engine oil is light brown to black in colour. It is also very greasy and slick and will appear under the front of your car. Engine oil is used to lubricate your engine and if this is leaking then you may smell the burning of oil when you drive your vehicle too. The technician will check your engine oil when the engine is cool, to get an accurate reading. You may do this yourself too, but do make sure that the engine is cool. It’s important to keep your engine oil in the range shown on the dipstick. If the engine oil happens to be on the low side frequently, then take it to a car leak repair garage.

Transmission fluid

Transmission fluid is reddish in colour and quite thin in consistency. It can also appear to be brown and thick and will appear in the middle and front of your car. Automatic transmissions are lubricated by transmission fluid, while manual transmissions are lubricated by gear oil. The technician will check your transmission fluid while the car is running and it is in neutral. In general, automatic transmission fluid should be checked while the car is running with the transmission in park or neutral. It’s extremely important to get a car technician to diagnose and repair transmission fluid leaks immediately.

Power steering fluid

Power steering fluid is amber, reddish, light brown in colour and appears at the very front of your car. Similar to brake fluid, the power steering fluid is a hydraulic fluid that aids power for the steering system. The garage will check your power steering fluid level when your car is not running. A leak in power steering fluid could reduce steering ability and control and is a definite risk. You must have your power steering fluid leaks checked right away, and avoid driving the car.

Coolant (anti-freeze)

Coolant is yellow, green or pink in colour, and it’s texture is greasy or slimy. It is another fluid that will appear to leak from the front of the car, near the radiator or under the engine. Cars need coolant to keep the engine from overheating. If your car is low on coolant or leaking coolant, you are at risk of overheating the car, which could damage your engine and your car could stop running anywhere, which means you may need roadside recovery. It’s extremely important that you get a technician to check this for you immediately, and you do not attempt to check it yourself, especially if the engine is hot, as the fluid is under extreme pressure and can cause extensive burns if not left to cool down. Book your car in with a garage if your car is leaking coolant right away.

Car leaking from near the wheels

Brake fluid

Brake fluid is clear through to yellow or brown, and will be visible near the wheels if it is leaking. Brake fluid assists the force of the braking mechanism of your car. If your brake fluid appears to be low, then there is a possibility that it is leaking. It is vital to have low or leaking brake fluid checked by a mechanic straight away, as brake fluid reservoirs are not large. Leak of even a small amount of brake fluid will impact your brakes.

Car leaking from the rear or near the exhaust


The majority of cars don’t use straight water in the cooling system. However, it can be used for the air conditioning system, and you may notice that it is leaking on especially warmer days when you are using the air con. Whilst it is not a catastrophic car leak, it is still a good idea to have your car checked by a professional.


Petrol is light gold and appears to look colourless when it falls to the ground. Diesel will leave a blue tint on the floor. Petrol or diesel powers your car to drive. As you know, fuel has a distinct smell, so if you smell excessive petrol or diesel around your car, or you see a car leak of this nature, then take it to a local garage immediately.

Fuel leaks often happen because there’s a crack or hole in the fuel tank. If the technician finds that the fuel tank isn’t rusting away due to age, they will be able to repair it without having to replace the whole thing.

Fuel leaks are a big risk to safety, because they can cause fires. You mustn’t drive your car if it is leaking fuel, because fuel leaks are highly flammable. Plus, your fuel economy will be worse off too.
