Diesel engines are known for their strength and reliability, but they come with their own set of problems when things go wrong. Fortunately, our diesel mechanics have the tools and know-how to tackle these common issues head-on.
Hard Starting and Slow Cranking
Cold starts, weak cranking, or trouble getting your diesel vehicle running can often be traced to faulty glow plugs, low compression, or fuel delivery issues. We’ll run diagnostics to isolate the cause and get your engine firing up strong again.
Fuel System Repairs
Clogged filters, dirty injectors, and worn fuel pumps can lead to poor performance, low efficiency, or even stalling. We clean, repair, or replace these components to restore proper fuel flow and engine health.
Turbocharger Service
If your diesel truck feels underpowered or is producing excess smoke, it might be due to a failing turbo. We inspect and service turbochargers to restore the power your diesel engine was built to deliver.
Exhaust Gas Recirculation (EGR) System Cleaning
Carbon buildup in the EGR system can choke diesel engines, reducing performance and increasing emissions. We clean or replace EGR valves to get your diesel vehicle running smoother and cleaner.
Diesel Particulate Filter (DPF) Service
A clogged DPF can trigger warning lights and reduce engine efficiency. We handle DPF cleaning or replacement to keep your emissions system functioning properly.
Injector Replacement
Misfiring, rough idling, and black smoke can mean your injectors are failing. We test and replace bad injectors to restore proper combustion in the combustion chamber.
Cooling System Repairs
Overheating can damage diesel systems, especially under heavy loads. We check the coolant, radiator, and related parts to keep your engine running at the right temperature.
Electrical Diagnostics and Sensor Testing
Modern diesel vehicles rely on sensors and computers to manage engine performance. We use up-to-date diagnostics equipment to identify and fix problems fast.
