Engine & Aftertreatment
Aftertreatment problems are usually engine problems wearing a disguise. We diagnose the fuel, air and cooling side properly before touching the emissions hardware, which is what keeps the repair from coming back three weeks later.
Engine repair
In-frame and component-level diesel repair
Cylinder head work, valve adjustment, gaskets and seals, oil leaks, low power and excessive blow-by. We scope the job against the duty cycle and the remaining life of the unit before recommending it.
Request this serviceDPF and emissions systems
Regen faults, sensors, DEF and derate diagnosis
Incomplete regen, repeat derates, DEF quality and dosing faults, differential pressure and NOx sensor problems, and cleaning or replacement of restricted filters. All work restores the emissions system to its required operating condition.
Request this serviceFuel systems and injection
Injectors, pumps, rails and return testing
Injector testing and replacement, high-pressure pump diagnosis, rail pressure faults, return-flow testing and contaminated fuel cleanup. Hard starting, rough running and low power usually resolve here.
Request this serviceTurbochargers
VGT actuators, boost faults and replacement
Variable-geometry actuator calibration and replacement, boost leak testing, wastegate faults, and turbo replacement with the root cause of the failure addressed so the new unit survives.
Request this serviceCooling system repair and diesel flush
Overheat diagnosis, radiators, flush service
Overheating diagnosis, radiator and charge air cooler service, water pump and thermostat replacement, fan clutch faults, and full diesel coolant flush with the correct specification coolant.
Request this serviceGlow plug service
Cold-start circuits, controllers and plugs
Glow plug, relay and controller testing and replacement, plus intake heater diagnosis. Addresses hard cold starting, rough warm-up and white smoke on start.
Request this serviceHard start and no start
Systematic fuel, air, compression and electrical
A structured no-start diagnosis covering electrical supply, fuel delivery and pressure, air intake and compression, rather than replacing parts in sequence until it fires.
Request this serviceAir system repair
Compressors, dryers, valves and leak isolation
Air compressor and dryer service, governor and valve faults, air leak isolation, and low-pressure or slow-build complaints affecting brakes and suspension.
