🗓 Different season, different ways your car can ruin your day.
Weather doesn’t break cars — weak parts do. Each season stresses a different system, and catching the early signs now saves you from sitting on the hard shoulder later.
Winter Watchlist ❄️
Battery Check
Cold mornings expose weak batteries quickly. If yours is 4+ years old, have it tested before the first frost. Slow cranking or dim interior lights are early warning signs.
Tip: Clean any white/green corrosion on the terminals to keep voltage strong.
Tire Tread & Pressure
Cold, wet roads demand grip. Anything below 3 mm reduces stopping power. Pressure also drops as temperatures fall, so check all tyres — including the spare — monthly.
Optional: If you live somewhere that gets regular frost, snow, or icy backroads, consider swapping to winter tyres for the colder months. They offer far better traction below 7°C.
Antifreeze (Coolant Strength)
Your coolant must be strong enough to prevent freezing. Frozen coolant can crack the radiator or even damage the engine. Most garages can test the coolant strength in seconds. If it’s weak or contaminated, get it changed before cold weather sets in.
Tip: If you’ve topped up with plain water during summer, a winter check is essential.
Washer Fluid
Road salt quickly blinds you in winter. Make sure your washer bottle is full and that you’re using winter-grade washer fluid — it stays liquid at low temperatures and prevents pump freeze-up.
Tip: Test your jets before winter trips. A blocked nozzle becomes a safety issue fast.
Summer Watchlist ☀️
Cooling System
Hot weather exposes every weak link in your cooling system — low coolant, cracked hoses, tired thermostats. An engine running hot in summer can boil over in minutes, especially in traffic or with the AC blasting. Check your coolant level, look for crusty white residue around hose clamps, and make sure the radiator fan kicks on.
Tip: If your temp gauge creeps higher than normal on hills or in traffic, get it checked before the heatwave arrives.
AC Performance
Weak AC isn’t just uncomfortable — it can signal low refrigerant, a failing compressor, or a blocked cabin filter. If the air takes ages to cool or isn’t cold at idle, it’s fading. Most shops can re-gas it quickly.
Tip: Replace the cabin filter yearly — half of “weak AC” complaints are just a clogged filter.
Tire Pressure
Heat expands air, raising pressure. An overinflated tire has less road contact, which means less grip and a higher chance of a blowout at motorway speeds. Always check your pressures cold, before driving.
Tip: If you’re carrying holiday luggage or extra passengers, add a couple of PSI — check the sticker inside the door.
Pro Tip:
Do these checks before the season starts. Nobody enjoys changing a battery in freezing rain or dealing with an overheating engine on a packed summer motorway.
