Australia’s diverse climate throws challenges at heavy vehicle operators throughout the year. From scorching summers to unpredictable wet seasons, being prepared for seasonal shifts is crucial. 

This guide will equip you with the knowledge and essential steps to prepare your heavy vehicle for seasonal changes. This is to ensure smooth operation and minimize downtime.


Spring: Shedding Winter’s Weight

Spring brings warmer temperatures and often increased rainfall. This makes it the perfect time to shed the weight of winter and prepare for busier summer months. Here’s what to focus on:

Fluid Check and Change

After a potentially harsh winter, engine oil, coolant, and other fluids might be nearing the end of their lifespan. Schedule a comprehensive service with a qualified mechanic to ensure all fluids are topped up or replaced with the appropriate seasonal grade.

Battery Inspection

Extreme winter temperatures can take a toll on batteries. Have your battery tested for voltage and cranking power. Consider replacing an aging battery to avoid a roadside breakdown during the hotter summer months.

Tire Inspection and Rotation

Spring showers often bring unpredictable road conditions. Check your tires for any winter-related wear and tear, including uneven tread wear or hidden cracks. Rotate your tires to ensure even wear and optimal performance. 

According to the National Heavy Vehicle Regulator (NHVR), “tire-related issues are a leading cause of roadside breakdowns for heavy vehicles in Australia.”

Brake System Check

Spring is a good time to have your brakes thoroughly inspected, including pads, rotors, and fluid levels. Promptly address any issues to ensure safe stopping power throughout the year.


Summer: Beating the Heat

Summer brings scorching temperatures and increased engine strain. Here are some key areas to focus on:

Cooling System Inspection

A properly functioning cooling system is vital to prevent overheating during the hot summer months. Have your mechanic inspect the radiator, hoses, and thermostat for any leaks, blockages, or signs of wear and tear.

Air Conditioning Maintenance

A functioning air conditioning system not only keeps your cabin cool but also helps to improve driver comfort and focus during long journeys. Schedule an AC inspection and service to ensure optimal performance.

Tyre Pressure Monitoring

Hot weather can cause tire pressure to fluctuate. Regularly monitor your tire pressure and adjust it according to the manufacturer’s recommendations for summer conditions. Overinflated tires can lead to blowouts, while underinflated tires can decrease fuel efficiency and handling.

Engine Oil Change

Use the recommended oil viscosity grade for summer temperatures. Consult your owner’s manual or a vehicle mechanic for the most suitable oil for your vehicle.


Autumn: Preparing for Winter’s Approach

Autumn serves as a transitional period to prepare your heavy vehicle for the colder winter months. Here’s what to prioritize:

Winter Blend Fluids

As temperatures begin to drop, consider switching to winter-grade engine oil and coolant to ensure optimal performance in colder weather.

Wiper Blade Replacement

Autumn rains can bring unpredictable weather conditions. Inspect your wiper blades for signs of wear and tear, and replace them if necessary, for optimal visibility during wet weather.

Light System Check

Ensure all headlights, taillights, brake lights, and turn signals are functioning properly. Shortening daylight hours in winter makes proper lighting crucial for safety on the road.

Battery Health Check

Before the cold winter sets in, have your battery tested again to ensure it has sufficient cranking power to handle the drop in temperature.


Winter: Maintaining Performance in the Cold

Winter can be particularly harsh on heavy vehicles. Here’s how to keep yours running smoothly:

Winter Blend Fluids

Ensure you’ve switched to winter-grade engine oil and coolant for optimal performance in cold weather.

Battery Care

Extreme cold can significantly reduce battery life. Keep your battery clean and free of corrosion. Consider investing in a battery maintainer to prevent it from draining during extended periods of non-use.

Fuel System Check

Winter weather can sometimes lead to condensation in the fuel tank, potentially causing issues with fuel quality. If you experience any problems with starting or engine performance, consult SEQ Heavy Truck Repairs to rule out any fuel system issues.

Windshield Washer Fluid

Top up your windshield washer fluid with a winter-appropriate formula to ensure clear visibility during snow or sleet.
