Engine Repair and Diagnostics
No-start diagnosis, injector failures, overheating, turbo issues, and check engine lights. All major diesel engines — Cummins, Detroit, CAT, PACCAR, and Volvo D-series.
Broke down on I-10, I-35 or I-45? One call connects you with a pre-vetted diesel mechanic dispatched directly to your location — any time, day or night.
How It Works
No hold music. No app to download. One phone call and we take care of the rest.
Tell us your location and what is wrong — no-start, DEF light, blown tire, engine warning. Takes 60 seconds.
We find the nearest available qualified mechanic for your breakdown type and confirm they are on the way. We collect the $45 dispatch fee at this point.
A vetted diesel technician comes to your exact location, diagnoses the problem, and repairs it on the spot. You pay them directly for parts and labor.
What We Repair
Our dispatched mechanics arrive equipped for the most common diesel breakdowns — no tow required for most jobs.
No-start diagnosis, injector failures, overheating, turbo issues, and check engine lights. All major diesel engines — Cummins, Detroit, CAT, PACCAR, and Volvo D-series.
DEF sensor faults and DPF regeneration failures are the leading cause of limp mode in modern big rigs. Our mechanics carry the diagnostic tools and parts to fix these on-site.
Fuel injector cleaning and replacement, fuel pump failure, contaminated fuel diagnosis, and fuel line leaks — resolved roadside without a shop visit.
Roadside tire changes, blowout repair, and emergency inflation — steer, drive, and trailer positions. We cover all Texas highways and commercial districts.
OBD and ECM diagnostic scans, battery and alternator failure, starter motor issues, and wiring faults traced and repaired on-site.
Refrigerated trailer cooling failures and cab air conditioning breakdowns handled by HVAC-certified technicians — critical in Texas heat.

About Texas Diesel Rescue
Finding a qualified diesel mechanic at 2 AM on a Texas highway is not easy. Texas Diesel Rescue solves that problem — we maintain a network of vetted 24/7 diesel technicians across Houston, Dallas, and San Antonio so that when your truck breaks down, one call is all it takes.
Every mechanic in our network has been verified for qualifications, insurance, and equipment before we ever dispatch them to a customer.
Our dispatch fee is a flat $45, charged when you call. No surprise fees from us. The repair cost is between you and the mechanic, discussed before any work begins.
No need to arrange a tow to a shop. Our mechanics bring the equipment to you — on the highway shoulder, at a truck stop, or at a loading dock.
