Mobile Diesel Mechanic in Houston

A diesel in a shop bay usually means days of waiting, a tow bill, and a truck that isn't earning. Most of what puts a diesel down — sensors, fuel and air issues, emissions faults, batteries and starting problems, leaks — can be diagnosed and repaired on site with the right tools. That's what the service truck is built for.

• Engine and ECM diagnostics
• Hard-start and no-start diagnosis
• Glow plug and cold-start systems
• Air, fuel and injector work
• Fuel delivery and filter service
• DPF and emissions-related faults
• Turbo and boost-leak diagnosis
• Cooling system and overheating issues
• Charging, batteries and heavy cabling
• Preventive maintenance and fluid service
• Roadside breakdown response

Excavators, skid steers, loaders and trailers get repaired where they're parked so nothing has to be hauled off the jobsite. That includes hydraulic lines, pumps and cylinders, electrical and starting systems, trailer lights, brakes and axles, and DOT-minded inspections.

• Extended cranking or no start when cold
• Loss of power or a regen that never completes
• Check-engine or derate warning on the dash
• White or excessive black smoke
• Boost or air leak whistle under load
• Rough running and hard idle
• Coolant temperature climbing under load
• Hydraulic function slow or dead on equipment

Send the make, engine, year and the fault codes if you have them, plus the location and whether the truck is loaded or blocking work. I confirm a window or roll out immediately for a breakdown, diagnose on arrival, and quote before any work starts. Full engine and transmission rebuilds and heavy machine work need a shop — I'll say so straight rather than start a job that can't be finished in the field.
