How Diesel Service Works at Our Shop
Diesel trucks that come through our doors start with a complimentary courtesy inspection before any repair decision is made. We use a free Digital Vehicle Inspection (DVI) that captures photos of your vehicle during the process, so you can see exactly what our technicians are seeing. From there, we walk you through the findings, answer your questions, and give you a clear picture of what your truck needs before we touch anything.
1. Schedule Your Appointment
Whether scheduling online or over the phone be sure and let us know what you're experiencing so we can provide fast and accurate service advice.
2. Diagnostics and Inspections
Drop off your vehicle and the shop will get to work with inspections and diagnostics using the same equipment as the manufacturers to determine issues and next steps.
3. Digital Vehicle Inspection Report and Estimate
Following the diagnosis we will text you a digital vehicle inspection report, containing pictures and videos of our findings and recommendations.
4. Review and Approval
A service advisor will reach out to walk you through the findings and recommendations to determine how you would like to proceed, or you can approve work directly in your DVI.
5. Work Performed or Scheduled
Most work can be completed immediately, or scheduled based on parts and customer availability.
Service Designed Around Your Schedule
We know dropping off your truck isn’t always convenient. Our complimentary shuttle service can take you where you need to go while your vehicle is being serviced and bring you back when it’s ready. You won’t need to rearrange your day around a repair appointment.
Owners Michael and Shayna Ortman are on-site, which means you’re dealing with people who are personally invested in your experience. Our waiting area is clean and comfortable, with free Wi-Fi and refreshments available if you prefer to stay.
Recognizing Diesel Engine Trouble
Diesel engines don’t always fail the same way gasoline engines do. Knowing what to watch for can help you catch a problem before it turns into a much larger repair.
These are the most common warning signs that a light-duty diesel truck needs attention:
- Exhaust smoke: Black smoke often points to fuel system or injector issues; white smoke can signal coolant intrusion or glow plug problems
- Hard starting: Particularly in cold weather, difficulty starting is a common sign of glow plug system wear
- Power loss: A noticeable drop in acceleration or towing capacity can indicate turbocharger or fuel delivery problems
- Unusual knocking: A pronounced knock under load often points to injector timing or fuel pressure issues
- Declining fuel economy: A steady drop in mileage with no change in driving habits warrants a diagnostic check
- Warning lights: An illuminated check engine light or glow plug indicator should be diagnosed promptly
Power Stroke, Cummins, and Duramax platforms each have their own known failure patterns. Our technicians read diagnostic codes in context, combining scan tool data with a physical inspection to give you an accurate picture of what’s actually going on.
Every repair we perform is covered by the Nice Difference Warranty: 3 years or 36,000 miles, whichever occurs last. Call (682) 688-9535 to schedule your diesel repair service at Christian Brothers Automotive Mansfield in Mansfield.
Diesel Maintenance: Staying Ahead of Problems
Routine maintenance on a diesel truck covers more ground than it does on a typical gasoline vehicle. Fuel filter changes are required more frequently because diesel fuel systems operate at much higher pressures and are more sensitive to contamination. The diesel particulate filter (DPF), which captures soot from the exhaust stream, needs periodic monitoring to avoid regeneration failures. The EGR system, which routes a portion of exhaust gases back into the intake to reduce emissions, is another component that benefits from regular inspection since carbon buildup can restrict flow and affect performance over time.
Turbocharger care and glow plug system checks round out the maintenance picture for most light-duty diesel owners. Turbos rely on clean, well-maintained oil for lubrication, and neglecting oil change intervals is one of the more common causes of premature turbo wear. Glow plugs, which preheat the combustion chamber to aid cold starts, tend to wear gradually rather than failing all at once, so periodic testing catches weakening plugs before hard starting becomes a problem.
Catching these issues early matters because diesel engines rely on tightly controlled fuel and emissions systems. A small problem left unaddressed can create stress on connected components. Staying current on maintenance is a cost-effective way to help protect your diesel truck over the long haul.
