The importance of a preventive maintenance program

If the cost of a preventive maintenance program worries you, consider the cost of not having one.

Vehicles that don’t receive regular maintenance experience a greatly reduced lifespan, excessive breakdowns, expensive repairs, lost time on the road and even litigation due to negligence.

In fact, in many ways, a preventive maintenance program for semi-trucks and commercial vehicles is as important as driver safety programs. An unsafe vehicle that is determined to create unreasonable risk or harm to a driver or others on the road – such as an accident because of bad brakes – could get the owner/manager prosecuted for liability or a negligent act.

In order to avoid any of these costly and scary issues it’s important to ensure your vehicle(s) is as safe as possible with consistent servicing, inspections and repairs to prevent problems and maximize the vehicle’s availability.

Preventive maintenance is about being proactive and regularly scheduling proper maintenance based on time, mileage, engine hours or gallons of fuel used. These maintenance actions include vehicle inspections, lubrication, adjustments, cleaning, testing, repair and worn parts department.


Be Proactive

Unscheduled and reactive maintenance to breakdowns and other problems is often a direct result of not being proactive and results in costly repairs and downtime for vehicles.

Whether you use an in-house, certified mechanic or take your vehicles to one, you should develop a consistent and effective preventive maintenance plan.

First, create a checklist of everything that should be performed.

Second, for each item make sure you know how frequent (based on mileage) each task needs performed or parts need changed.

Third, make sure you develop a good record-keeping system, which can be manual or electronic, to evaluate your plan.



Before you develop your checklist and routine, make sure you consult the vehicle manual for manufacturer’s recommendations. From there, develop a preventive maintenance checklist that includes at least:

  • Engine oil and filter changes
  • Transmission fluid
  • Fuel system
  • Cooling system
  • Engine and transmission mounts
  • Drive shafts or CV joints
  • Belts and hoses
  • Tune-ups
  • Electrical system components
  • Braking system
  • Steering and suspension system
  • Tires, wheels, rims
  • Exhaust system
  • Undercarriage and frame
  • Exterior and interior lights
  • Body, glass and mirrors
  • Windshield wiper system
  • The horn
  • Seatbelts and seats
  • Checks fluid leaks and the auxiliary systems.


Also, it’s important the mechanic or fleet owner/operator speaks with the driver to see if there are any problems they’ve noticed while on the road. This allows the mechanic to pinpoint any issues that may not be immediately visible.

Once you’ve come up with a checklist and began to implement your preventive maintenance schedule, keep an eye on costs to see the value of your plan. Detailed, regular reports on your preventive maintenance will help you keep track of how your efforts are working and how they can be improved as time goes on.
