Winter Driving Safety Checklist for Victorian Drivers
Battery and charging system
Cold reduces a battery's cranking capacity at exactly the time the engine oil is thicker and harder to turn. A battery that managed fine in January can fail in June, because the chemical reaction that makes the battery work slows down as the temperature drops. We load-test the battery, check the resting voltage, and check the charging output with the engine running and the load on. If it's marginal, better to know before it's flat on a seven degree morning in a carpark in Epping. We fit Neutron Power batteries and test the whole charging circuit so the new one isn't working against a weak alternator.
Tyres for wet roads
Wet grip drops as the tread wears. The legal minimum in Victoria is 1.5mm, but wet braking distance gets longer well before that, and the car will aquaplane in standing water on a tyre that's near the limit, because the tread can't clear the water out from under the contact patch. We check the tread depth on each tyre, the pressures, and the wear pattern. Cold weather drops tyre pressures too, so we reset them to the placard figure. If the car's been pulling or wearing unevenly, a wheel alignment before winter stops the wet-weather pull and the scrubbed tread that costs you a set before spring.
Brakes and brake fluid
Wet roads mean longer stopping distances, which is the worst time to find out the brakes are soft. We measure the pad thickness, check the rotors for scoring and minimum thickness, and test the pedal feel. Brake fluid over two years old has absorbed moisture, and moisture in the fluid boils under heavy braking, which is how a firm pedal goes spongy right when you need it. If it's due, we bleed the system with fresh fluid. A brake that pulls in the wet is a seized caliper, and we catch that before the wet road finds it for you.
Visibility in the short days
Short days mean you're driving in the dark at both ends, and a blown globe is easier to miss when you're not looking. We check the headlights high and low beam, the taillights, the number plate light, the reversing lights, and the indicators. Wiper blades that streak or chatter get replaced, because a smeared windscreen in driving rain is how you miss the car that stopped in front of you, and a fogged screen is a blind screen. We check the washer jets hit the screen and the washer bottle's full, because an empty washer in July is a surprise you don't want on the way home from work.
Coolant and hoses
The cooling system works harder in summer, but a hose that fails on a cold morning can strand you just as fast, because the rubber gets harder in the cold and a hard hose splits. We check the coolant level and condition, and the radiator and heater hoses for splits, swelling, and softness where the rubber's perished. Coolant that's due for a flush gets done before it turns acidic and eats the heater core from the inside. A winter service is the time to sort it, because a burst hose on the Tullamarine Freeway in the dark isn't the time to find out the rubber's gone.
The wipers nobody thinks about
Wipers are the one item drivers forget until the first downpour, and then they wonder why they can't see. Wiper rubber perishes in the sun over summer and goes hard before winter, so the blade smears instead of clearing. We replace the blades at a winter check, and we check the washers aim at the screen, not the roof. A fresh set of blades and a full washer bottle is the difference between seeing the road and guessing at it in a downpour, and it's the cheapest safety item on the list.
Key Takeaway
Bring the car in before the cold hits and we'll run the whole winter list, battery, brakes, tyres, visibility, and coolant, and hand it back ready for the wet. Call Ben on 03 9193 6500. If the battery's already slow, our battery or alternator guide tells you why the cold makes it worse.
