Common questions
Can a diesel mechanic come to my truck, or does it need a shop?
A lot can be handled where the truck sits. Batteries, starters, filters, diagnostics, forced regen, and many sensor repairs are mobile-friendly. Heavy engine work, lift work, or driveline jobs usually go to a shop.
My truck is derated. Can I still drive it?
Maybe for a short move, but do not keep working it hard. A derate means the truck is protecting the engine or aftertreatment system. The mechanic scans it first and tells you whether it is safe to move.
Do you work on Power Stroke, Duramax, and Cummins pickups?
Yes. Those are common Corpus Christi service calls, especially for work trucks, RV tow vehicles, and fleet pickups. Medium-duty Isuzu, Freightliner, International, and Hino work routes to a technician with the right scan tools.
Can you do a forced regen?
Yes when the truck is in the right condition for it. If the soot load, sensor data, or exhaust temperatures are out of range, the mechanic fixes the cause first instead of just forcing another regen.
Is diesel repair licensed in Texas?
Texas does not issue a state diesel mechanic license. We look for ASE diesel or medium-heavy truck credentials, EPA Section 609 when A/C work is involved, proper insurance, and real diagnostic documentation.
Do you service commercial fleets?
Yes. Small fleets can schedule oil, filters, grease, brake checks, DOT-style inspection notes, and repair tracking. Port, refinery, and delivery routes around the Coastal Bend usually need tighter maintenance intervals because idle time and stop-and-go work add up.
What if the truck needs towing?
If it cannot be repaired safely on site, we route the tow to a light, medium, or heavy-duty operator based on the truck size. The diesel tech can still send scan notes ahead so the shop starts with useful information.
Can you handle fuel contamination?
Yes. The mechanic checks for water, algae, or bad fuel, then quotes the filter service, tank work, or injector-system testing needed. Do not keep cranking it if the truck picked up contaminated fuel.
Coastal Bend seasons
Spring (March - May)
Hail and severe weather bring more roadside calls and fleet damage checks. Pollen and humidity can also expose air intake and electrical issues.
Summer (June - August)
Heat is hard on batteries, cooling systems, and aftertreatment. Trucks idling at jobsites or refinery gates need closer attention to coolant, belts, and regen history.
Fall (September - November)
Hurricane prep should include batteries, tires, wipers, fuel filters, and a scan before evacuation or storm-response work. Diesel fleets get busy before named storms in the Gulf.
Winter (December - February)
Cool starts expose weak glow plugs, batteries, and fuel-delivery problems. Scheduling is usually easier for preventive maintenance.
