Looking for fast diesel repair in Dallas, TX? Your truck is down and every hour it sits costs you money. Hawkeye Diesel Repair sends certified diesel mechanics straight to your breakdown location anywhere in Dallas, from the I-35E corridor to the DFW Airport freight terminals. We answer 24 hours a day, 7 days a week, including holidays.
We are a locally owned mobile diesel repair company based in the Dallas-Fort Worth area. Our technicians carry OBD-II and ECM diagnostic tools, common replacement parts, and the training to work on Class 8 semi-trucks, dry vans and flatbed trailers, heavy equipment, and diesel pickups on site. No tow truck. No shop wait times. We come to you.
When you search for a diesel mechanic near you in Dallas, you want someone who can get to your location fast and fix the problem on the first visit. That is exactly how we operate.
Our mobile diesel repair service covers all of Dallas County and the surrounding area. We dispatch from our Mansfield shop on the Fort Worth side of the metroplex, so our typical response time to central Dallas runs 60 to 90 minutes depending on traffic and your exact location. Jobs closer to the I-30 corridor or western Dallas see us faster. Locations near Mesquite, Garland, or eastern Dallas County may take slightly longer.
We are upfront about this because your time matters. When you call, we give you an honest ETA before we roll.
What you get with every mobile service call:
Breakdowns do not follow a schedule. A blown turbo hose on I-30 at 2 AM or a no-start at a loading dock in the Stemmons Corridor at midnight needs immediate attention. Our 24/7 emergency diesel repair service exists for exactly these situations.
We handle emergency calls across Dallas and the DFW metroplex, including:
If you need a 24/7 diesel mechanic near you, contact us and we will have a technician en route quickly. We carry common emergency parts on our trucks so many roadside repairs are completed in a single visit.
Our mobile certified diesel technicians in Dallas handle the same repairs a full shop would, but we bring the shop to you. See our full range of diesel repair services. Here is what we service on site:
Fuel system problems cause hard starts, rough idle, power loss, and poor fuel economy. We diagnose and repair injectors, fuel pumps, fuel filters, fuel pressure regulators, and supply lines. If your rig is burning through diesel faster than normal or losing power under load, this is usually where the issue lives.
We use ECM diagnostic tools to pull fault codes, read live data, and pinpoint engine problems fast. Common issues we see on Dallas job sites include misfires, excessive black or white smoke, turbo failures, and loss of power on grades. We troubleshoot and repair on site whenever possible.
A dead truck in a Dallas freight yard is lost revenue. We diagnose and fix batteries, starters, alternators, wiring harness issues, and charging system failures. No-start conditions are one of our most common emergency calls. We carry replacement batteries and starters on our service trucks for same-visit repairs.
A trailer fault sidelines the load just as fast as an engine fault. Dallas runs on freight, and most of our Inland Port and DFW Airport cargo calls are trailer work, not tractor work. We service:
Dry van, flatbed, or reefer chassis, we work on the trailer where it sits. No drop yard. No detaching the tractor.
Emission system problems trigger warning lights and can derate your engine, cutting power and speed. We service DPF (diesel particulate filter), EGR (exhaust gas recirculation), SCR (selective catalytic reduction), and DEF systems on site. Our technicians clear fault codes, perform forced regenerations, and replace failed components to get your truck back to full power and keep it compliant.
Dallas heat puts extra stress on cooling systems, especially during summer months. We repair radiators, water pumps, thermostats, hoses, and coolant leaks on site. If your temperature gauge is climbing or you are losing coolant, call before the engine overheats. Catching a failing water pump early costs a fraction of a full engine rebuild.
We handle clutch adjustments, clutch replacements, driveshaft repairs, U-joint replacements, and axle service on site for semi-trucks and heavy-duty rigs. If your truck is hard to shift, slipping, or making noise from the drivetrain, we can diagnose and repair it at your location.
Scheduled maintenance prevents breakdowns. We perform oil changes, filter replacements (oil, fuel, air, coolant), fluid checks, belt and hose inspections, brake checks, and full multi-point inspections at your yard or job site. Regular PM service costs a fraction of what emergency repairs cost and keeps your equipment on the road longer.
If you manage a fleet of commercial trucks, trailers, or heavy equipment in Dallas, we offer scheduled on-site maintenance programs built around your operation. We come to your yard on a set schedule, service your equipment, and track every repair and maintenance event.
Our fleet program includes:
We work with owner-operators running a single rig and fleet managers running 50+. The program scales to your needs. If your fleet operates out of Dallas, Irving, Mesquite, Garland, or anywhere in Dallas County, we can build a schedule that fits.
Our technicians are trained and equipped to work on all major diesel truck and engine brands. We regularly service:
We also service dry van, flatbed, reefer, and tanker trailers from every major builder, including Great Dane, Utility, Wabash, and Hyundai Translead.
If your brand is not listed, call us. We likely work on it. Our diagnostic tools cover most diesel platforms on the road today.

Our mobile diesel mechanics serve all of Dallas and the surrounding metro area. We travel to your location, whether that is a fleet yard in West Dallas, a loading dock near the Inland Port, or a highway shoulder on I-635.
Dallas neighborhoods and areas we cover:
Surrounding cities within our Dallas dispatch range:
We also serve Fort Worth, Denton, and Weatherford from our home base. For a full list, see our service area page.
Do not ignore these symptoms. What starts as a minor issue can turn into a major breakdown that costs thousands more than an early repair.
If you notice any of these, call Hawkeye Diesel Repair before a roadside breakdown forces the decision for you.

Your rig is not making money sitting broken. Call Hawkeye Diesel Repair now for 24/7 mobile diesel service anywhere in Dallas and the DFW metroplex. We dispatch certified diesel mechanics to your location, diagnose the problem with professional ECM tools, and get you back on the road.
Need diesel engine repair or diesel truck service? We handle both. Call today or schedule service online.
When your truck or trailer breaks down, finding a mechanic you trust at 2 AM is hard. Hawkeye Diesel Repair answers the phone and rolls a service truck to your GPS pin. No tow. No waiting for a shop to open.
Yes, every hour of every day, holidays included. A no-start at a Stemmons Corridor dock at midnight or a blown turbo hose on I-30 at 2 a.m. reaches a live dispatcher at (682) 231-8338, not a voicemail or an answering service.
We stage from our Mansfield shop on the Fort Worth side of the metroplex, so central Dallas calls average 60 to 90 minutes. The I-30 corridor and West Dallas run shorter, while the far eastern county past Garland and Mesquite runs longer. You get a real ETA before we commit a truck.
Usually, yes. Most derates trace to aftertreatment faults: DPF, EGR, SCR, or DEF system codes. Our techs pull the codes with OEM scan tools, force a regen or replace the failed component, and clear the derate so you can move the load instead of waiting on a tow.
Both. Trailer work is a large share of our Dallas calls, especially around the Inland Port and the DFW Airport cargo terminals. We handle trailer air brakes, ABS faults, landing gear, suspension, tires, and lighting on site. If your trailer is the reason the load is not moving, that is our call to take.
Yes. We cover the full Dallas freeway grid: I-35E, I-30, I-45, I-20, I-635 (LBJ Freeway), and the PGBT. Service trucks carry scan tools, common parts, and fluids for on-shoulder repair. If the job needs a lift or a press, we tow it to our Mansfield shop.
You get a quote before any work begins. A call runs a dispatch charge plus flat hourly labor and parts. Dallas sits at the longer end of our dispatch range, so ask about the trip charge up front and we will give you the number straight. No shop markup, no surprise lines.
Mixed fleets are routine around the Inland Port and the Great Southwest Industrial District. We run Class 8 tractors (Freightliner Cascadia, Kenworth T680, Peterbilt 579, International LT, Volvo VNL, Mack Anthem), trailers, medium-duty trucks, and diesel pickups (Powerstroke, Cummins, Duramax) off the same service truck.
Cummins X15 and ISX, Detroit DD15 and DD13, PACCAR MX-13, Caterpillar C15, Navistar, plus Duramax 6.6L and Powerstroke 6.7L. If your platform throws a code, our tools most likely read it.
Yes. We build recurring on-site PM for fleets in Dallas, Irving, Mesquite, and Garland: oil and filters, brake and DOT inspections, fluid service, and per-unit digital records for tractors and trailers. Fleet accounts also get priority dispatch when something does break.
