Cold mornings punish the small things first: a tired battery, a worn wiper, a washer bottle run dry. Ten minutes with the bonnet up and a torch will find most of it before the first hard frost.
Ten minutes, ten checks
- Washer fluid. Top up with a winter mix, not plain water, and check the bottle is not frozen.
- Wipers. Lift the blades and look at the rubber. A split edge smears the screen and is worse in the cold.
- Tyres. Check the tread across the width of each tyre, not just the outer edge, and set the pressures when the tyres are cold. Use the handbook figures, not the number on the sidewall, because pressure drops as the temperature falls.
- Lights. Walk round the car with the lights on: headlamps, main beam, indicators, brake lights and number plate lamp. Ask someone to press the brake pedal.
- Battery. Look at the terminals for white crust and check the clamp is tight. A weak battery that starts in October can fail in January.
- Coolant. Check the level when the engine is cold. Top up with the correct mix, not neat water, and never open the cap when the engine is hot.
- De-icer and scraper. Keep both in the car, not the garage. A credit card is not a scraper.
- Brake feel. On a quiet road, at low speed, check the pedal feels firm and the car stops in a straight line. A soft pedal or a pull needs attention.
- Screen. Clean the screen inside and out, and clear the washer jets.
- Boot kit. Check the boot has a torch, a warning triangle, a warm layer and a charged phone cable.
Why each one matters
Most winter breakdowns are small failures made worse by cold. A washer bottle that freezes leaves you with a screen you cannot see through. A battery at the end of its life has less margin when the oil is thick and the heater is on. A tyre with shallow tread clears far less water than one with a deep pattern, and the difference shows in the first rain after a dry spell.
None of these checks replaces a service. They are the things you can see and reach in ten minutes, and they buy you time to book the jobs that need a ramp.
Under the bonnet and under the car
Washer, coolant and battery checks happen with the car on level ground and the engine off. If you need to go under the car for anything, use axle stands under the handbook points, never just a jack. Torque any wheel bolts to the handbook figure after refitting a wheel. When you buy a part, check the fitment notes and compare it with the part you are replacing. Listed for your model is a starting point, not a promise.
Before the first frost
Do the check on a dry afternoon rather than a dark morning. Top up, replace what is worn and note anything that needs a proper look. Keep the boot kit in the car all winter, and carry a coat you would be willing to stand in at the roadside.
Ten minutes now is a better use of a Sunday than twenty minutes scraping ice on a Monday, and a much better one than waiting for a recovery truck.
