Weekly Car Checks Every Owner Should Do: Keep Your Vehicle Road-Ready

Owning a car comes with the responsibility of keeping it safe and reliable, and a few simple weekly checks can make all the difference. Regular maintenance not only prevents breakdowns but also ensures your vehicle stays roadworthy, potentially saving you from costly repairs down the line. Here’s a straightforward guide to the essential checks you should carry out every week.

1. Check Your Tyres

Your tyres are your car’s connection to the road, so keeping them in top shape is critical:  

Tread Depth: Use a tread depth gauge or the “20p test”—insert a 20p coin into the main grooves; if the outer rim is hidden, your tread is above the UK legal minimum of 1.6mm. Replace tyres below this limit.
Pressure: Check your owner’s manual or the sticker inside the driver’s door for the recommended pressure (in PSI or bar). Use a tyre pressure gauge (available at petrol stations) and inflate if needed—don’t forget the spare!
Condition: Look for cuts, bulges, or uneven wear. These could signal damage or alignment issues requiring professional attention.

2. Inspect Fluid Levels

Fluids keep your car running smoothly, so top them up weekly:  

Engine Oil: Park on level ground, wait for the engine to cool, then check the dipstick. If the oil is below the minimum mark, add the recommended type (check your manual). Look for a dark, gritty texture—time for an oil change if it’s dirty.
Coolant: Check the reservoir (never open it when hot!) and top up with a 50/50 water-antifreeze mix if it’s low. Low levels could overheat your engine.
Windscreen Washer Fluid: Ensure the tank is full with a washer fluid mix—crucial for clear visibility in bad weather.
Brake Fluid: Locate the reservoir under the bonnet and check it’s between the min and max lines. Low levels? Get it checked by a mechanic pronto.

3. Test Your Lights

Faulty lights can land you a fine and compromise safety:  

Headlights, Taillights, and Indicators: Turn them on (low and high beams) and walk around the car—or ask a friend to help. Replace any blown bulbs.
Brake Lights: Press the brake pedal while someone checks the rear lights work.
Fog Lights: Test these if fitted, especially in autumn and winter when visibility drops.

4. Examine the Windscreen and Wipers

A clear view is non-negotiable:  

Windscreen: Look for chips or cracks. Small chips can often be repaired, but cracks over 40mm (or 10mm in the driver’s swept area) fail an MOT in the UK.
Wiper Blades: Run them with washer fluid to ensure they clear the screen without streaking. Replace worn or split blades—they’re cheap and easy to swap.

5. Check the Battery

A dead battery can leave you stranded:  

Terminals: Look under the bonnet for corrosion (white or greenish buildup) on the battery terminals. Clean with a wire brush if needed but wear gloves.
Performance: If the engine struggles to start or lights dim, test the battery with a multimeter (12.6 volts is healthy) or visit a garage.

6. Listen and Look for Warning Signs

A quick once-over can catch issues early:  

Strange Noises: Listen for squeaks, rattles, or grinding when starting or driving—these could indicate brake, belt, or suspension problems.
Dashboard Warnings: Check for illuminated warning lights (e.g., oil, engine, or brakes). Don’t ignore them—consult your manual or a mechanic.
Leaks: Look under the car for puddles—oil (black), coolant (green/pink), or brake fluid (clear/yellow) leaks need urgent attention.

7. Fuel Level

It sounds basic, but don’t let it run too low:  

Gauge Check: Ensure you’ve got enough fuel for the week ahead. Running on fumes can damage your fuel pump, especially in diesel cars.

Why Weekly?

These checks take just 10-15 minutes but can spot problems before they escalate. In the UK, driving an unroadworthy vehicle can lead to fines up to £2,500, points on your license, or even a ban—so it’s worth the effort. Plus, with MOTs and insurance on the line, staying proactive keeps you legal and safe.

Tools You’ll Need

Keep these handy:  

Tyre pressure gauge
20p coin
Rags and gloves
Fluids (oil, coolant, washer fluid)
A torch for evening checks
