Diesel Repair & Service

Diesel trucks earn their keep towing trailers, hauling equipment, and racking up highway miles, and they need technicians who understand how they're built. Diesel repair has been a core part of our work at Pristal's Automotive since 2003, and we service Ford Power Stroke, Ram Cummins, Chevrolet Duramax, and other diesel platforms.

Every diesel job starts with a free diagnostic scan and a digital vehicle inspection. We pull fault codes, review live engine and fuel system data, and look for the root cause, whether that's a failing injector, a sticking turbocharger, a clogged diesel particulate filter (DPF), or an emissions component like the EGR valve or DEF system. Diesel symptoms often overlap, and a code rarely tells the whole story, so hands-on experience makes a real difference here.

Once we've confirmed the problem, we walk you through the findings and a written estimate before any work begins. You'll get text updates while your truck is in the bay, so you can plan your workday around it instead of waiting by the phone.

Our ASE-certified technicians, including ASE Master Technicians with factory training, handle a full range of diesel work:

• Fuel injector testing and replacement
• Turbocharger diagnosis and repair
• DPF cleaning and regeneration problems
• EGR and DEF system repair
• Glow plug, starting, and charging system service
• Diesel oil changes and scheduled maintenance

When a truck can't be driven in, our discounted towing gets it to us without adding more cost to a rough day. Courtesy loaners keep you moving while we work, and Snap Finance makes larger repairs easier to manage. Every diesel repair is covered by our 36-month/36,000-mile warranty, honored nationwide, which matters for trucks that cover a lot of ground. We're AAA Approved and a TechNet Professional shop, and we keep your truck's service history documented through our digital inspections, which helps with resale and warranty claims down the road. Diesel owners from Magnolia, Hockley, and Waller trust us to diagnose accurately, explain clearly, and get the repair right the first time.
