Hawkeye Diesel Repair dispatches mobile Certified Diesel Technicians to your breakdown location anywhere in the Dallas-Fort Worth metroplex. Our service trucks carry diagnostic scanners, OEM parts, and hydraulic tools so we fix your truck on-site, not at a distant shop.
A diesel breakdown costs more than the repair bill. Every hour parked is lost revenue and HOS clock ticking away. These problems send drivers searching for a mobile diesel mechanic near me at 2 a.m.:
Hawkeye Certified Diesel Technicians diagnose and resolve these issues at your location. We bring the shop to your truck so you skip the tow bill.
Our mobile units handle the same scope of work you would get at a full service bay. Hawkeye Certified Diesel Technicians perform on-site ECM diagnostics for Cummins, PACCAR, Detroit Diesel, and International engines using Cummins INSITE, JPRO, and OEM scan tools.

Hawkeye mobile Certified Diesel Technicians work on every diesel-powered truck and equipment class in North Texas:
Whether you run a single owner-operator rig or a 50-truck fleet out of Dallas or Fort Worth, we have the tools and parts to handle the job on-site.
Step 1. Call or text our dispatch line. Tell us your truck make, model, engine type, and the symptoms. Describe your location, whether it is a truck stop on I-35, a job site in Arlington, or a yard in Denton.
Step 2. We confirm your estimated arrival time. Mansfield-area response runs 30 to 45 minutes. For the wider DFW metroplex, including Weatherford and I-20/I-35 corridor cities, expect 45 to 75 minutes.
Step 3. Certified Diesel Technician arrives and diagnoses the problem. We plug into the ECM, run fault code analysis, and perform a visual inspection. Before any wrench turns, you get a clear explanation of the issue and a cost estimate.
Step 4. On-site diesel repair begins. Our trucks carry common replacement parts for Cummins, Detroit Diesel, PACCAR, and International engines. Most roadside repairs finish within 1 to 4 hours.
Step 5. Final test and documentation. We clear fault codes, road-test the repair when possible, and provide a written invoice. Fleet managers receive digital service records for each unit.
