Winter Car Care: 10 Essential Checks to Run During Winter

Winter doesn't just make your morning drive colder. It puts real strain on your car. Batteries lose power, tyres lose pressure, and visibility drops just as the roads get slicker. None of this is dramatic on its own but skipped together, It's exactly how a "fine" car turns into a breakdown on a freezing morning. 

The good news: none of the fixes below need a mechanic's toolkit. Most take five minutes at home or a quick stop at a servo. Here are the 10 checks worth doing now, during winter. 

1. Check your tyre pressure

 Tyres lose pressure as temperatures drop: a well-known rule of thumb is roughly 1 PSI for every  5.5°C the temperature falls, so a tyre set correctly in autumn can be noticeably under-inflated by the time winter hits. Under-inflated tyres reduce grip and make a car feel sluggish or unstable, especially on wet roads. Check pressures monthly against the figures on your door-sill placard (not the tyre sidewall), and always check when the tyres are cold for an accurate reading. 

2. Inspect tread depth 

Wet winter roads make tread depth far more important than it feels in dry weather. The legal minimum is 1.5mm tread depth in most Australian states, but tyre manufacturers generally recommend replacing tyres once they hit 3mm for reliable wet-weather grip, since worn tread struggles to channel water away and increases the risk of aquaplaning. If you're not sure how yours are tracking, a tread depth check from a MyMoto dealer takes a few minutes. 

3. Test your battery: especially if it's 3+ years old 

Cold weather is the number one cause of dead batteries in winter, because low temperatures slow the chemical reactions that generate starting power. A battery that started your car fine all summer can suddenly fail on the first genuinely cold morning. If yours is more than three years old, or you've had to jump-start it recently, get it load-tested now, during winter. Call your nearest MyMoto Service Partner and get a battery check booked in, it will only take a few minutes.

4. Clean and check battery terminals 

Corrosion on battery terminals reduces the connection's conductivity, which compounds any power loss from the cold. A quick visual check for white or greenish buildup, and a clean with a wire brush if needed, is cheap insurance against a no-start morning. 

5. Top up and check fluids 

Cold weather thickens engine oil and makes every fluid work harder. Check your coolant/antifreeze level (it protects against both overheating and freezing), top up windscreen washer fluid with a winter-rated mix, and keep an eye on oil condition; thick, sludgy oil circulates poorly in the cold and puts extra load on a battery that's already under pressure. 

6. Replace worn wiper blades 

Fog, rain and shorter daylight hours make your wipers one of the most-used parts of the car in winter. If they're streaking, skipping or squeaking, replace them before the first big downpour rather than during it. One tip worth knowing: never use your wipers to clear ice off the windscreen. It can damage the rubber blades. Use a proper ice scraper instead, and avoid the washer sprayer in freezing conditions, as the water can freeze on contact with the glass. 

7. Check all your lights 

Shorter days mean more driving in low light or darkness, and fog and rain reduce visibility further. Walk around the car and check headlights, tail lights, brake lights and indicators are all working. It's a five-minute job that makes a real difference to how visible you are to other drivers. 

8. Check demisting and heating 

A functioning demister isn't a comfort feature in winter. It's a safety one. Fogged-up windows are a common, underrated hazard on cold mornings. Make sure your air-con and demister are blowing properly and clearing the windscreen quickly; if they're sluggish, it's worth getting checked before you're relying on them daily. 

9. Check your alternator belt 

A loose or worn alternator belt is a common, often-overlooked cause of battery drain, since the alternator is what recharges your battery while you drive. If your battery seems to be losing charge for no obvious reason, a frayed or cracked belt is worth ruling out. 

10. Get an overall service check-up 

If it's been a while since your last service, winter is a good trigger to book one. A winter service check bundles most of the above into a single visit: tyres, battery, fluids, belts and lights, and picks up smaller issues (like a hairline coolant hose crack) before they become breakdowns. 

The bottom line 

Winter doesn't damage your car overnight. It just exposes whatever was already borderline. A tyre that was a little low, a battery that was a little old, wipers that were a little worn. Running through this checklist now, during winter, is the difference between a smooth season and a very unpleasant Tuesday morning on the side of the road.
