The black smoke coming from your diesel engine’s exhaust usually indicates that there is too much fuel and not enough air. This is usually caused by clogged filters as well as faulty injectors or a struggling turbocharger needing inspection.
Most heavy duty diesel engines need oil changes every 15,000 to 25,000 miles though severe duty as well as idling and heavy loads shorten that interval.
Power loss often stems from restricted fuel flow and a failing turbocharger as well as clogged air filters or low compression weakening combustion under heavy strain.
Common signs include rough idling as well as hard starting or increased fuel consumption and black smoke. These signs are all pointing to injectors that need cleaning or replacement.
Overheating usually results from coolant leaks as well as a worn water pump or due to clogged radiators and failing thermostats that block proper heat dissipation during extended use.
