Caring for your car this winter

As daylight saving is about to end, it's time to not only start thinking about winter heating, but caring for your car during the cool spells.

The Automobile Association of New Zealand has a winter checklist that includes a few simple and inexpensive tips that will help keep you mobile during the colder months.

Cooling system

Most modern cars have anti-freeze inhibitors, but it's a case of making sure they are sufficient for cold conditions. If you haven't got enough anti-freeze in the coolant system, the engine may freeze up. The engine is put under extreme pressure and components may crack.

Live in a cold part of the country? Think about your cooling system. Heading down to the mountain for a spot of skiing? Don't forget the anti-freeze.

Wheels

Tyres with borderline tread will impede the removal of water in bad weather. It is critical water is dispersed from under the tyre when driving in wet conditions. Tyres that can't grip can't keep you safe. In extreme weather, you need to rely on the sticking power of your vehicle's tread.

Check your car tyres have adequate tread depth (standard tyres must have 1.5mm over three-quarters of the tyre around its entire circumference, while snow tyres have a 4mm requirement) and confirm your tyre pressures are correct.

Coping with wet weather

Damp weather can put more stress on electrical systems. A service reduces these mechanical pressures. Deep water and brakes don't mix. Remember, water is a lubricant, so if you drive through a flooded area and submerge your wheels, your brakes won't work effectively. Using them a few times once you're out of that water will help to dry the disks out and get them working again.

To do this, pump the brakes a few times to get them back into working order if you've driven through water and submerged your wheels.

General tips

- Have your car serviced before winter sets in.

- Carry an effective torch in the car and make sure it has working batteries.

- Keep warm clothing or a rug in the car. If your vehicle breaks down, you might need an extra layer.

- Keep your cellphone charged. You never know when you might need it.
