International Truck Repair Near You

When you run International equipment, you need a shop that speaks the language of Diamond Logic Electrical System, understands Cummins B6.7 and L9 Engines, and can tame that notorious High Efficiency Cooling Module. General Diesel’s ASE-Master techs plug straight into OEM software to pinpoint issues fast, whether it’s a quirky sensor or a complete in-chassis overhaul.

Typical signs that you should book a service include erratic idle, loss of boost, coolant surge, ABS lights linked to the Bendix Wingman Fusion, or sluggish Remote Diagnostics Capabilities uploads. We’ll perform thorough electrical sweeps, fluid analysis, and on-truck calibrations, then road-test the vehicle to confirm that it meets factory specifications. From turbo replacements to harness repairs, our mission is to help you avoid costly roadside failures and keep those loads moving.

Common International Troubles We Tackle

  • No-start or derate after software updates
  • Aftertreatment clog warnings
  • Air-brake leaks impacting Wingman Fusion calibration
  • Cooling fan faults that trigger limp-mode

What Makes Us Different

Most owners dread the time and mark-ups at dealership bays. At General Diesel, independence means flexibility and savings. Because we’re not tied to OEM profit targets, we source quality parts at honest prices and pass the difference on to you. Our workforce comprises military veterans, overseas field mechanics, and former dealership professionals, so there’s almost no engine platform or chassis configuration we haven’t encountered. Every technician carries ASE Master credentials, and our laptops run genuine International ServiceMaxx and Nav-Kal calibration suites for bullet-proof results.

You’ll talk directly with the technician working on your truck, receive photos of progress in real-time, and get clear options before any additional work begins. The result? Less downtime, predictable costs, and a partnership built on transparency, not sales quotas.

FAQs

What Areas Do You Serve For International Repair?

We are located at 2150 Iron Rod Court, North Charleston, SC, near the I-26 and North Rhett Avenue interchange. We also proudly serve Charleston County, SC, Dorchester County, SC, and Berkeley County, SC, within our 30-mile service radius.

What Engine Options Are Available In The International MV Series?

International’s medium-duty MV frames commonly ship with either the Cummins B6.7 or L9 diesel. The B6.7 covers 200-325 hp for city delivery work, while the larger L9 stretches to 380 hp, giving fleets extra torque for vocational upfits or heavier regional hauls. Both share DOC/DPF systems and electronic fuel systems optimized for duty cycle flexibility.

How Does The Bendix Wingman Fusion System Enhance Safety In International-Brand Trucks?

Wingman Fusion integrates forward radar, camera, and brake controllers to deliver adaptive cruise control, lane departure warnings, and automatic emergency braking. By continuously triangulating distance and lane markers, it can cut throttle and apply brakes faster than driver reaction time, reducing rear-end collisions and minimizing downtime from accident-related repairs.

Amg Boss

"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!!"

Kevin Vivis

"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!"

Harris Borden

"I had a complex electrical fault in my Kenworth T680 truck. They did everything they could and finally detected the fault and repaired it. I would like to thank especially KENNY, who has years of experience in this business, and the owner of the business and the other employees. If you have a Kenworth truck, you should definitely go to GENERAL DIESEL, not a Kenworth dealer."
