3 key fluids for your car

Cars are a complex collection of moving parts and components, many of which need the proper lubrication to operate safely and effectively. There are several key fluids found in your which keep it running smoothly. If you're looking to sell your car for cash, this is one area to be vigilant about.

A car that's in sound shape is also more likely to respond as anticipated on the road, so it's doubly important to be aware of the fluids in your vehicle and when they may need a top up. 

Here is a quick guide to the fluids in your vehicle and how to tell if they're in need of a little TLC.


Your car needs oil like you need water – it lubricates the engine and keeps the parts from wearing down faster. You can check the oil in your car regularly on your own but consult your mechanic if you're unsure when to get it replaced.

Simply pop open the bonnet, take out the dipstick from the oil reservoir and wipe it completely clean before dipping and drawing it out again. Measure the level of oil on the stick against the markings to see whether you're under, over or just right. 

Radiator coolant

Coolant is an antifreeze substance is used to stop your engine from overheating, which can be dangerous for you – not to mention expensive to fix. To check your coolant level, wait till your engine has become cold before popping the radiator cap and checking that the liquid is at or near the top.

You should also check the level of coolant in the tank. This is translucent, so all you need to do is see how much is sitting in there. 

Brake fluid

Brake fluid keeps this vital component of your car working properly. It's clear in colour (if clean) and should be replaced with the correct type of fluid for your vehicle – check your owner's manual for the exact details if you are unsure. 

Be very careful when handling brake fluid as it can damage your eyes, and always make sure everything is sealed off properly before getting back behind the wheel.
