What is Preventive Maintenance?

Preventive maintenance is a proactive approach to vehicle and equipment care to identify and address potential issues before they become major problems. It involves a comprehensive inspection and maintenance routine, covering vital components such as engines, transmissions, brakes, tires, and more. By regularly performing preventive maintenance, you can extend the lifespan of your heavy-duty vehicles and equipment.

We offer a range of preventive maintenance services tailored to meet the specific needs of light, medium, and heavy-duty trucks and equipment:

  • Engine Inspections and Tune-ups: We thoroughly inspect and tune up your engines to ensure they are operating efficiently, reducing fuel consumption and emissions. This includes inspecting coolants, lubricants, filters, and serpentine belts. 
  • Brake System Maintenance: We provide comprehensive brake system checks and maintenance to guarantee optimal stopping power and safety on the road. This includes inspecting the air system and brake shoes for proper function. 
  • Fluid and Filter Changes: Regular fluid and filter changes are vital for maintaining the health of your equipment. We handle oil changes, transmission fluid checks, and filter replacements to keep your machinery running smoothly.
  • Tire Inspections and Rotations: Proper tire care is essential for safety and performance. We conduct tire inspections, rotations, and replacements when necessary to extend tire life and improve fuel efficiency.

I've been looking for someone for the passed 30 years and I finally them. The work I had done was very professional and kept me up to date on my vehicles,  ie would it cost me more or they found something we were not aware of.  I'm also ready to leave my 3rd vehicle service which will need ,check engine light,front end work,exhaust system and so on. Very reasonable labor rate I recommend all my family and friends.
