Regular Oil and Fluid Services

One of the most important aspects of diesel vehicle maintenance is regular oil and fluid service intervals and maintaining those intervals on a consistent basis. This includes oil changes, filter replacements, and fluid checks. Regular oil changes are crucial to keeping your engine lubricated and free of contaminants. Filter replacements ensure that your engine has a clean supply of fuel and air. Fluid checks are important to monitor the health of your transmission, power steering, and cooling systems.

Engine Repair Services

Engine problems can be caused by various factors, including wear and tear, lack of maintenance, or faulty components. Engine repairs can range from minor issues like injector replacements to major overhauls. At KingFleet, our technicians use state-of-the-art equipment and technology to diagnose and repair engine problems quickly and effectively.

Exhaust System Services

The exhaust system is an essential part of your diesel vehicle's engine. It helps to regulate emissions and improve engine performance. A damaged or clogged exhaust system can cause a decrease in fuel efficiency and engine performance. At KingFleet, we offer exhaust system repairs and replacements, including muffler and catalytic converter services.

Fuel System Services

A diesel vehicle's fuel system is responsible for delivering fuel to the engine and maintaining the correct fuel pressure. A malfunctioning fuel system can lead to decreased fuel efficiency and engine performance. At KingFleet, we offer fuel system cleaning, repairs, and replacements to keep your diesel vehicle running smoothly.

Transmission Services

The transmission is a crucial component of your diesel vehicle and is responsible for transmitting power from the engine to the wheels. A malfunctioning transmission can cause a decrease in fuel efficiency and engine performance. At KingFleet, we offer transmission repairs, rebuilds, and replacements to keep your diesel vehicle shifting smoothly.
