Nicks Automotive provides diesel repairs for trucks and vehicles in Lubbock, Texas
If you rely on a diesel truck or vehicle in Lubbock, you know how quickly a rough idle, loss of power, or hard starting can disrupt your day. Whether you use your diesel for work, hauling, or daily driving around Lubbock, the engine needs to perform consistently under load and across temperature swings that come with West Texas conditions.
Nicks Automotive handles diesel repairs that address fuel system issues, turbocharger problems, glow plug failures, injector wear, and cooling system leaks. We work on diesel engines found in light-duty trucks, heavy-duty pickups, and commercial vehicles, diagnosing issues with scan tools and hands-on testing to identify what is causing the symptoms you are noticing behind the wheel.
Keeping your diesel running strong
When you bring your diesel vehicle to Nicks Automotive in Lubbock, we start by gathering information about the symptoms you have noticed, such as unusual smoke color, delayed acceleration, warning lights, or changes in fuel economy. We connect diagnostic equipment to read fault codes and monitor live data from sensors that control fuel delivery, air intake, exhaust pressure, and engine temperature.
Once we identify the source of the problem, we explain what needs to be repaired or replaced and what you can expect after the work is done. You will notice smoother starts, quieter operation, restored pulling power, and in many cases, a return to normal fuel efficiency once the repair is complete.
Depending on the issue, repairs may involve cleaning or replacing fuel injectors, testing glow plugs and relay circuits, inspecting turbocharger boost levels, checking EGR valve function, or replacing filters and fluids that affect combustion quality. We let you know if a repair requires ordering parts or if the work can be completed the same day, and we avoid recommending services that are not directly related to the issue you came in for.
What Happens During a Diesel Repair
Questions people usually ask before booking
Diesel owners in Lubbock often want to know how long a repair will take, what caused the problem, and whether it is something that could happen again. These are the questions we hear most often when someone brings in a diesel vehicle.
How do you know what is wrong with a diesel engine?
We use a combination of diagnostic scan tools and manual tests to check fuel pressure, air flow, sensor signals, and exhaust behavior. Fault codes give us a starting point, but we also rely on visual inspection and performance testing to confirm the actual cause.
What causes a diesel to lose power when accelerating?
Loss of power can come from restricted fuel filters, failing injectors, turbocharger issues, or air intake blockages. We check each system to identify where the restriction or failure is occurring and what needs to be repaired to restore full power.
Why does my diesel blow black or white smoke?
Black smoke usually means too much fuel or not enough air, often due to clogged filters or turbo problems. White smoke can indicate unburned fuel from injector issues or coolant entering the combustion chamber, which requires immediate attention.
How long does a typical diesel repair take?
Simple repairs like glow plug replacement or filter changes can be done in a few hours. More involved work such as injector replacement or turbo service may take a full day or require ordering parts, depending on your vehicle and the issue we find.
Can I keep driving my diesel if it is running rough?
You should avoid driving it if you notice severe loss of power, overheating, or unusual smoke. Continuing to drive with a known fuel or turbo issue can cause further damage to the engine and lead to more costly repairs down the road.
