Summary

• Perform quick 5-minute checks weekly: inspect tyre pressure and condition, test all lights, and check wipers and screenwash fluid.
• Conduct a monthly health check: verify the engine oil, coolant, and brake fluid levels when the engine is cool.
• Regularly performing these basic checks helps prevent costly breakdowns, improves fuel efficiency, and ensures your vehicle is safe to drive.

Let’s be honest, car maintenance can feel like a chore. For many, popping the bonnet is as inviting as a trip to the dentist. But what if I told you that a few simple, regular checks could save you a mountain of cash, keep you safer on the road, and make you feel a whole lot more confident behind the wheel?

This isn't about turning you into a grease-covered mechanic overnight. It’s about creating an essential car maintenance checklist of routine tasks that quickly become second nature. Think of it as a 5-minute coffee break with your car once a week. These basic fluid checks, tyre pressures, and lights inspections are the bedrock of a healthy, happy vehicle and one of the best ways to cut your motoring costs.

So, grab a cuppa, and let's walk through it. No jargon, no nonsense. Just what you need to know.

The Rhythm of the Road: Checks by Frequency

The secret to not feeling overwhelmed is breaking it down. You don’t need to check everything all at once. By splitting tasks into weekly, monthly, and occasional checks, it becomes manageable and easy to remember.

The 5-Minute Weekly Once-Over

Do these quick checks every week or two, or at the very least, before any long journey. This is your first line of defence against common problems.

1. Tyres: Your Connection to the Road

Everything your car does—steering, braking, accelerating—happens through four patches of rubber, each about the size of your hand. Giving them a quick look is arguably the most important check you can do.

Tyre Pressures

Ever tried riding a bike with flat tyres? It’s hard work, wobbly, and unsafe. It’s the same for your car. Incorrect pressure wears tyres out unevenly, uses more fuel, and dangerously affects braking and handling.

• How? Find the correct pressure on a sticker inside the driver's door jamb, inside the fuel flap, or in your owner's manual. Check them when they're "cold" (i.e., before you've driven anywhere). A simple pressure gauge is a great tool to have in your glovebox.

Tread & Condition

Good tread clears water away, preventing you from aquaplaning on wet roads.

• How? Use the 20p test. Pop a 20p coin into the main tread grooves. If the outer band of the coin is hidden, your tread is above the legal limit (1.6mm). If you can see that band, your tyres are getting low and it's time to think about replacing them. While 1.6mm is the legal minimum, for better grip in wet or icy weather, it's wise to change them when they get down to 3mm. You can find out more in our guide to the dangers of low tyre tread.
• Also, give the tyre walls a quick glance. Are there any cuts, cracks, or bulges? A bulge means the tyre's internal structure is damaged and it could fail at any moment. Get it checked professionally, immediately.

2. Lights: See and Be Seen

This one is simple. Are all your lights working? It’s not just about you seeing the road, it’s about other drivers seeing you and knowing what you’re about to do.

• How? With the ignition on, check your headlights (dipped and main beam), indicators, and fog lights. To check the brake lights and reverse lights, you can either ask a friend to help or simply reverse towards a reflective surface like a garage door or shop window at night. Don’t forget the number plate light – you can be fined if it’s out!

3. Windscreen, Wipers & Washer Fluid

Your view of the road is everything. A dirty windscreen can be blinding in low sun or at night.

• Wipers: Check the rubber blades for any splits or tears. If they’re leaving streaks or making a horrid screeching noise, it’s time for a new pair. They’re usually cheap and surprisingly easy to change yourself.
• Screenwash: Is the washer bottle topped up? It’s a legal requirement to have fluid in it. Using a proper screenwash additive is much better than just water, as it has cleaning agents and won't freeze in winter, which could crack the bottle or pipes.

The Monthly Health Check

These checks take a tiny bit more effort but are just as crucial. Set a reminder on your phone for the first Sunday of every month.

1. Engine Oil: The Lifeblood

Oil is to your engine what blood is to your body. It lubricates, cleans, and cools all the fast-moving metal parts. Running low on oil is one of the fastest ways to destroy your engine, leading to a bill that costs thousands.

How to Check:

1. Make sure your car is on level ground and the engine is cool.
2. Find the dipstick – it usually has a brightly coloured (often yellow or orange) loop handle.
3. Pull the dipstick out and wipe it clean with a rag or paper towel.
4. Push it all the way back in, wait a second, and pull it out again.
5. Check the oil level against the 'MIN' and 'MAX' marks. It should be somewhere between the two.

What if it's low? If it’s near the MIN mark, you need to top it up. Unscrew the oil cap (it will have an oil can symbol on it) and add a small amount of the correct oil for your car (check your handbook!). Don't just glug it in; add a little, wait a minute for it to settle, and re-check the dipstick. Overfilling can be just as bad as underfilling.

2. Coolant: Keeping a Cool Head

This fluid, also known as antifreeze, stops your engine from overheating in summer and from freezing solid in winter. An overheating engine can cause catastrophic damage.

• How to Check: NEVER, EVER open the coolant cap when the engine is hot. The system is pressurised and can spray scalding hot liquid. Wait for the engine to be completely cool.
• Look for the coolant reservoir (a semi-transparent tank). It will have 'MIN' and 'MAX' lines on the side. The level should be between these marks. If it’s low, top it up with the correct type of coolant/antifreeze for your car. If you're wondering what the signs of an overheating engine are, we've got you covered in our guide on how to check if your engine is overheating.

3. Brake Fluid

This one sounds scary, but it’s a simple visual check. Brake fluid is part of a hydraulic system that gives your brake pedal its power.

• How to Check: Find the brake fluid reservoir (check your handbook for the location). Like the coolant tank, it will have 'MIN' and 'MAX' levels. The fluid should be between them.
• A quick note: Brake fluid is nasty stuff that can damage paintwork, so be careful. If the level is low, it could mean your brake pads are worn or there's a leak. It’s best to get this checked by a professional.

The Occasional & Annual Stuff

You don't need to worry about these as often, but it's good to keep them in mind. They are usually covered in your annual MOT and service.

The Final Word

See? Not so scary. This essential car maintenance checklist isn't about adding another job to your to-do list; it’s about making these routine tasks, fluid checks, and inspections of tyre pressures and lights a simple, empowering habit.

Taking five minutes to perform these vehicle safety checks can be the difference between a safe, uneventful journey and a stressful, expensive breakdown on the side of the M1. It puts you in control, connects you with your car, and gives you the peace of mind that you’ve done your bit to keep yourself, your passengers, and other road users safe.
