Winter Car Service Checklist: 10 Checks Before the Cold

Ten winter checks for your battery, tyres, antifreeze and more, plus what to ask when you book a car service near me before the first frost.

Before the cold arrives, check ten things: battery, antifreeze, tyres, wipers, screenwash, lights, heater and air con, brakes, fluid levels and your emergency kit. Some you can do yourself in ten minutes; the rest are best covered by booking a car service near me in autumn, before the first frost. Winter exposes weak parts quickly, and a breakdown on a dark, cold evening is far harder to deal with than a check in October.

This checklist explains what to look at, why each item matters in winter and which checks need a technician.

The 10 winter checks at a glance

Check	Why it matters in winter	Who should do it
1. Battery	Cold reduces battery performance just as demand rises	Technician test
2. Antifreeze (coolant)	Protects the engine from freezing and overheating	Level: you. Strength: technician
3. Tyres	Grip on wet, cold and icy roads	You, plus a check at service
4. Wipers	Clear vision in rain, spray and sleet	You
5. Screenwash	Road salt and grime smear the screen	You
6. Lights	Longer hours of darkness	You
7. Heater and air con	Fast demisting of the windscreen	You, technician if weak
8. Brakes	Longer stopping distances on wet roads	Technician
9. Oil and fluid levels	Low levels add strain in the cold	You
10. Emergency kit	Keeps you safe if you are stranded	You

Checks 1 to 3: battery, antifreeze and tyres

1. Battery

Car batteries commonly last around 3–5 years, and winter is when a tired one gives up. Warning signs include a slow, laboured start, dim lights when cranking and a battery warning light. If your battery is in that age range, ask for a test before the cold sets in. Start-stop cars use EFB or AGM batteries, so a replacement must match the type. Our car battery guide explains more, or see battery replacement.

2. Antifreeze

Coolant, often called antifreeze, protects the engine in both directions: it stops the water freezing and helps prevent overheating. With the engine cold, check the level sits between the minimum and maximum marks. A technician can test its strength. Coolant is usually green, pink, orange or blue with a sweet smell, and it is toxic to pets, so clean up any drips.

3. Tyres

The legal minimum tread is 1.6mm across the central three-quarters of the tread, around the whole circumference. Many experts recommend replacing nearer 3mm, which matters most on cold, wet roads. Check pressures monthly, as they drop in cold weather, and look for cuts or bulges. Our guide to MOT tyre rules covers the law in detail.

Checks 4 to 7: seeing and being seen

4. Wipers

Replace blades that smear, judder or leave streaks. Free frozen wipers from the screen before switching them on, as this can tear the rubber and strain the motor.

5. Screenwash

Top up with a screenwash suitable for low temperatures. Plain water can freeze in the bottle and the pipes.

6. Lights

Walk round the car with the lights on: headlights on dipped and main beam, sidelights, indicators, brake lights, fog lights and the number plate light. Clean the lenses regularly, as winter grime dims them.

7. Heater and air con

Running the air con with the heater dries the air and clears a misted screen faster. If demisting is slow, or the heater is weak, have it checked. Clear water under the front passenger side after using the air con is usually normal condensation.

Checks 8 to 10: brakes, fluids and your kit

8. Brakes

Stopping distances grow on wet and icy roads, so brakes need to be at their best. Listen for squealing or grinding and watch for the car pulling to one side. Brake fluid is commonly changed about every 2 years, following the manufacturer. See signs your brakes need immediate attention.

9. Oil and fluid levels

Check engine oil on level ground with the engine cold, and look under the car for leaks. Our guide on checking fluid levels at home walks you through it.

10. Emergency kit

• Ice scraper and de-icer
• Torch with spare batteries
• Warm coat, blanket and gloves
• Phone charger
• Water and a snack
• Hi-visibility vest

Booking a winter car service near me: what to ask

A pre-winter service is the easiest way to have the technician checks done together. When booking, ask that the battery is tested, the coolant strength checked and the brakes inspected, and that any findings are shown to you before work goes ahead. If you are in Southampton, Eastleigh, Totton, Hedge End, Chandlers Ford or Romsey, see our Southampton page.

With Hon Car Service, you choose a mobile mechanic at home or work, free collection and return, or drop-off at a trusted local garage. You get live photo updates, approve any extra work first, and your card is only charged after the work is done and approved. Work carries a 12-month parts and labour warranty.

Frequently asked questions

When should I book a winter car service near me?

Autumn is ideal, before the first frosts. Booking early gives you time to deal with anything the check finds.

Can a mobile mechanic do winter checks?

Yes. Servicing, battery testing and replacement, and most of the checks above can be done on a driveway or in a car park.

Is my battery likely to fail in winter?

If it is around 3–5 years old or already showing a slow start, the risk is higher. A battery test will tell you where it stands.

How do I find a garage near me for these checks?
