Preventive maintenance is about choosing when your truck is out of service instead of letting a breakdown choose for you. This checklist is a starting point — adjust it to your engine manufacturer's schedule and your routes.
Daily and pre-trip checks
- Walk around the truck and look for leaks under the engine and around hoses
- Check engine oil and coolant levels
- Check lights and reflectors
- Look at the dash after start-up — note any warning lights
- Listen for new noises and pay attention to changes in how the truck drives
Oil and filter service
Change oil and filters on an interval based on your engine manufacturer's recommendations and your duty cycle. Our guide on how often to change oil explains how to set that interval. We offer Delo and Shell Rotella T6 synthetic diesel oil changes.
Periodic inspection items
A truck inspection — done at your truck — covers these in more depth and gives you a written list of findings.
- Belts and hoses for cracks, wear and leaks
- Battery condition, terminals and charging system
- Cooling system condition
- Air intake and filter condition
- Visible wiring and connectors
- Exhaust and aftertreatment components for leaks or damage
Act on warning lights quickly
A light that stays on is a problem that's waiting to get bigger. Book diagnostics early — it's usually cheaper than waiting. It also reduces the chance of surprises at your next Clean Truck Check.
Keep useful records
- Date, mileage and engine hours for every service
- Oil brand and viscosity used
- Parts replaced and part numbers
- Warning lights, fault codes and how they were resolved
- Clean Truck Check test dates and results
Frequently asked questions
Can you set up a maintenance schedule for my fleet?
Yes. We can help small fleets plan oil changes, inspections and testing so trucks aren't all out of service at the same time.
