Talk diesel with us — (303) 529-6712Diesel Problems Need Diesel Testing
Diesel engines work hard here: towing, plowing, cold starts at altitude and long pulls on I-70. When one starts smoking, losing power or cranking too long, the cause is usually in the fuel, air or emissions system, and each of those has its own tests.
Diesel repair at Auto Repair Dumont uses the same diagnosis-first approach as every other job. Injector balance rates, boost pressure, glow plug resistance and emissions system data get checked before any expensive part is recommended. Diesel parts are costly, so proving the fault first saves real money.
What Diesel Repair Covers
Common diesel work includes:
Injector testing and replacement
Balance rates and return flow show which injectors are failing, so you do not replace a full set when one is bad.
Turbocharger diagnosis
Lost boost is traced to the turbo, a leaking intercooler hose or a stuck vane before a turbo is quoted.
Glow plugs and cold starts
Glow plugs, relays and controllers are tested so the truck starts on the coldest mornings.
EGR system repair
Clogged EGR valves and coolers cause smoke and power loss; they are cleaned or replaced.
DPF and regeneration faults
Diesel particulate filter problems are diagnosed, including why the filter is not regenerating.
Fuel delivery problems
Lift pumps, high-pressure pumps, filters and water contamination are tested and corrected.
Diesel head gaskets and coolers
Oil and coolant cooler failures and head gasket leaks on diesel engines are repaired.
Sensor and wiring faults
Pressure, temperature and NOx sensors and their wiring are tested before replacement.
How Diesel Repair Works
Gather the symptoms
When does it smoke, lose power or crank long: cold, hot, under load? That steers the test plan.
Test each system
Fuel, air and emissions systems are tested in turn until the fault is isolated.
Repair and road-test
Once you approve, the repair is made and the truck is driven under load to confirm it pulls cleanly.
