A breakdown on the highway costs far more than a few minutes of checks every day – lost trips, repair bills, late deliveries and sometimes accidents. This truck maintenance checklist is written for owners and drivers of Mazdas, 10-wheelers and trailers.
Daily checks (before every trip)
- Walk around the truck: leaks under the vehicle, damage, loose parts.
- Tyres: pressure, cuts, bulges and wheel nuts.
- Lights and indicators, including brake lights and reflectors.
- Fluids: engine oil, coolant, brake/air system, power steering.
- Brakes: test pedal feel and air pressure build-up on air-brake trucks.
- Load and straps: secure, balanced, not overloaded.
- Documents: registration, fitness, route permit, licence, bilty.
Weekly checks
- Battery terminals and water level (for non-sealed batteries).
- Belts and hoses for cracks.
- Greasing of moving parts as recommended.
- Air filter cleaning, especially in dusty areas.
- Mirrors, wipers and horn.
- Fifth wheel and kingpin on trailers.
Monthly checks
- Brake lining and drum or disc wear.
- Suspension springs and bushes.
- Steering play and alignment.
- Exhaust leaks and engine smoke colour.
- Tyre rotation and spare tyre condition.
Service by distance
Follow the maker’s service schedule for oil and filter changes, coolant, transmission and differential oil. Hard routes – heavy loads, hills, dust and heat – often need shorter intervals.
Keep records
Write down each service, part change and repair with date and mileage. Records help you spot repeated problems, plan costs and sell the truck at a better price later.
Signs you should stop and check
- Warning lights, sudden loss of power or high temperature.
- Pulling to one side when braking.
- New noises, vibration or burning smells.
