6 Car Checks to Do Before Autumn (UK)

The short answer: run these six checks before the weather turns and you'll dodge most of the breakdowns that clog UK recovery services from October onwards. Cold mornings flatten weak batteries, wet leaves and standing water wreck tyre grip, and tired wipers smear everything instead of clearing it. Each check takes under ten minutes, needs no special tools, and only costs money if you find a problem. Here's the full checklist, in the order that matters.

1. Check the battery before the first cold morning

Dead batteries are the most common autumn breakdown, because cold weather slows the chemistry inside them at exactly the moment the starter motor needs more. If the engine cranks slowly or the dash lights dim when you start it, the battery is on the way out. Clean any white corrosion off the terminals with a wire brush and hot water, and if the car has been standing for a while, take it for a proper 30 minute drive to put the charge back.

You can't always see a failure coming, which is why keeping a jump starter in the boot is the cheapest insurance on this list. The GOOLOO GP2000 jump starter starts petrol and diesel cars without needing another vehicle, doubles as a power bank for your phone, and costs about £45, which is less than a single breakdown callout. We compared the full range in our best jump starters UK roundup.

2. Check tyre tread and pressure, including the spare

Wet roads mean your tyres are the difference between stopping and aquaplaning. The legal minimum tread depth in the UK is 1.6mm across the central three quarters, but grip drops off noticeably below 3mm in standing water. The 20p test is a decent rough check: push a 20p coin into the tread and if the outer band stays flush or visible, the tyre needs replacing.

Pressure matters just as much, and it drifts as temperatures drop. Check it monthly on cold tyres using the figures on the sticker inside the driver's door. A Ring RAC635 digital tyre inflator plugs into the 12V socket, shows the live pressure and shuts off at the target you set, which turns the job into a five minute driveway task instead of a queue at the garage. For the rest of the winter kit, our essential car accessories guide has you covered.

3. Replace worn wipers and top up the screenwash

Wiper blades last six to twelve months in UK weather, and once the rubber hardens they smear instead of clearing. If yours leave streaks or judder across the glass, replace them before the first proper downpour. Most are a two minute swap with no tools, and the fitting guide is printed on the packet.

Use the same trip to top up the washer fluid with a winter-grade screenwash. The Rain-X washer additive cleans the glass and leaves a hydrophobic coating that makes rain bead off at speed, and it protects the system down to freezing so the jets don't ice up in November.

4. Walk round and check every light

Dark mornings and evenings mean other drivers see you by your lights alone, and a single failed brake light is both dangerous and an MOT failure. Get someone to sit in the car and work through the switches while you walk round, or use a reflective surface to check the brake lights yourself. Check headlights, dipped beam, indicators, reverse, fog lights and the number plate light, and wipe the lenses clean while you're there.

Bulbs are cheap and most are easy to swap yourself. If you're not confident, a quick garage visit for a bulb is still far cheaper than a fine or a bump in the dark.

5. Top up the coolant and check the antifreeze

The cooling system works year round, but autumn is when it gets tested. Check the coolant level in the expansion tank when the engine is cold and top up with the correct mix for your car. The antifreeze concentration matters because it protects against frost damage to the engine block, not just overheating, and UK winters can easily hit temperatures that thin coolant can't survive.

If you're not sure the mix is strong enough, a cheap antifreeze tester from any motor factors gives you the answer in thirty seconds. Never open the radiator cap while the engine is warm, and if you're losing coolant regularly, get it looked at before it turns into a head gasket bill.

6. Listen to the brakes and restock the emergency kit

Brakes get noisier as they wear, so listen for squealing when you pull up. Any grinding noise means the pads are down to the metal and need attention right away. Check the brake fluid against the MIN mark on the reservoir, and if the level keeps dropping, there's a leak or worn pads that need a professional look.

While you're at it, check your breakdown kit matches the season. The Voilamart 12-in-1 emergency kit bundles jump leads, a tow rope, a warning triangle, a hi-vis vest, a torch and a few extras in one bag for about £25, which beats discovering you have nothing but a spare tyre when it's dark and raining.
