About Our Preventive Maintenance Services

Preventive maintenance is the most effective way to reduce unexpected breakdowns, extend component life, and lower long-term operating costs. Regular inspections and scheduled servicing allow worn parts, fluid contamination, and minor mechanical issues to be identified before they develop into major repairs.

For fleets and owner-operators throughout North Charleston and the Lowcountry, a preventive maintenance program helps improve reliability, maintain fuel efficiency, and keep trucks operating safely. Staying on top of routine service also supports DOT compliance and reduces the risk of costly downtime that can disrupt deliveries and daily operations.

Guide to Preventative Maintenance Services:

Preventative maintenance services encompass a range of checks and repairs to ensure every aspect of the truck is in top condition. This includes routine inspections of the engine, brakes, electrical systems, and other critical components. Scheduling regular preventative maintenance is key to identifying wear and tear early, preventing major failures, and maintaining the truck's value.

  • Oil and Filter Changes: Regular oil and filter changes are fundamental to maintaining engine health. They keep the engine clean and lubricated, reducing wear and tear on moving parts. Fresh oil and a clean filter improve engine efficiency and longevity, making these changes an indispensable part of preventative maintenance.
  • Fluid Level Checks and Replacements: Checking and replacing fluids such as coolant, brake fluid, and transmission fluid are vital for truck operation. These fluids play key roles in the functioning of various systems, and low or contaminated fluids can lead to system failures. Regular fluid checks and replacements ensure these systems function effectively and prevent damage.
  • Tire Inspections and Rotations: Tire inspections and rotations are essential to ensure even tire wear and prolong tire life. This includes checking tire pressure, tread depth, and overall tire condition. Regular tire maintenance ensures safe driving conditions and improves fuel efficiency, making it a critical element of preventative maintenance.
  • Brake System Checks: Regular brake system checks are crucial for safety. This involves inspecting brake shoes, drums, and s-cam for damage. Early detection of wear or damage in the brake system can prevent brake failure and ensure the safety of the vehicle and its occupants.
  • Electrical System Assessments: Electrical system assessments involve checking the battery, alternator, and wiring. These checks are essential to prevent electrical failures that can lead to breakdowns. Regular electrical assessments ensure the truck’s charging system, lighting, and electronic controls are functioning properly.

Signs Routine Maintenance Should Be Scheduled

Preventive maintenance helps address normal wear before it develops into a repair. Changes in fluids, tires, braking, or engine behavior can indicate that service intervals are being stretched too far. Keeping maintenance current can help reduce premature component wear and keep the vehicle operating more consistently.

  • Dirty Oil: Engine oil appears contaminated or overdue
  • Low Fluids: Reservoir levels repeatedly fall below normal
  • Uneven Tires: Tread wear develops irregularly
  • Brake Wear: Stopping performance begins gradually changing
  • Poor Mileage: Fuel consumption increases unexpectedly
  • Overdue Service: Recommended maintenance intervals have passed

"I HIGHLY RECOMMEND THIS SHOP TO ANYONE IN THE AREA, NEEDING ANY REPAIRS DONE!!!!Every one of them were very polite, transparent, courteous, and respectful. My truck needed 2 new injectors, they ordered them IMMEDIATELY. Since the truck wasn’t going to be done that day, the one owner gave me a ride to the hotel, avoiding me from getting an uber. The next morning the other owner, out of his own pocket, got me an uber back to their shop. These guys are very knowledgeable in what they do!!"

"My experience at General Diesel has been absolutely wonderful. The workers there show great customer service and the service on my vehicle was terrific. I recently brought my vehicle into the shop last Friday and ask for it back by Wednesday. I really wasn’t expecting for the vehicle to be serviced and complete, but General Diesel had the issue with the vehicle complete by Tuesday evening. Thank you General Diesel. I will definitely be coming back soon!"
