International Truck Repair

That's a design that replaced older Navistar engines and brought its own diagnostic quirks along with it.

Our diagnostic tools read International's specific fault codes across the A26 engine and the truck's electrical architecture.

That means we can pinpoint whether a problem is coming from the engine, a sensor, or the wiring between them.

We don't just replace parts based on a guess that might miss the cause entirely.

International Issues We Handle

• A26 engine diagnostics and repair
• Electrical and sensor faults
• Transmission repair
• Brake, suspension, and tire service
• Mobile roadside repair anywhere in DFW
• Fuel system and DPF repair

What Makes the A26 Different

The A26 uses a compacted graphite iron block and a different turbo setup than International's older MaxxForce engines.

That means techs who last worked on an older International truck sometimes bring outdated assumptions to a newer LT or RH.

Our techs stay current on this platform specifically.

Assuming it behaves like the previous generation leads to wasted diagnostic time and, occasionally, the wrong part getting ordered.

Coverage Across DFW

The result is an International truck that's back on the road with the problem fixed, whether that repair happens roadside or needs a shop visit.

Whether your International is down at a dock in Mesquite, near Fuel City off I-20, or on the shoulder near Fort Worth, we can help.

Our mobile techs carry the tools for this platform.

Call 972-703-4445 now and tell us what your International is doing.

We'll send a tech to your location, or reach us through our Request Truck Repair page.

LT Series vs Older ProStar Models

International's LT series, built around the A26 engine, replaced the older ProStar and its MaxxForce engine options.

The two platforms are different enough that parts and diagnostic approaches don't overlap much at all.

So knowing which generation you're running matters more here than it does on some other brands.

Why the A26's Turbo System Gets Its Own Attention

The A26 uses a two-stage turbocharging setup that behaves differently under load than a traditional single turbo design.

A boost related fault code can point to a completely different repair, depending on which stage is having trouble.

Our techs check both stages independently rather than assuming a single turbo failure pattern.

RH Series for Regional and Vocational Work

The RH series shares the A26 engine.

But it's often spec'd for regional or vocational use rather than long haul.

That sometimes means different auxiliary equipment wired into the truck.

If you're running an RH with added equipment like a PTO or auxiliary hydraulics, mention that when you call.

It can affect where an electrical fault traces back to.

International's Vocational Truck Line

International builds a range of vocational trucks like the HX series, alongside its highway focused LT and RH models.

These often have different engine tuning and auxiliary power setups for specialized work.

If your International is a vocational build with added equipment, that context helps our tech anticipate what's wired into the truck beyond the standard configuration.

International's OnCommand Connection

International's OnCommand telematics system can flag certain fault conditions before a driver notices any symptom at all, similar to remote monitoring on other brands.

If your truck or fleet uses this system, mention any alerts it's already generated when you call.

They can point our tech straight at the issue.
