Preventive Maintenance

Preventive maintenance is key to keeping your diesel engine running smoothly. Regular oil changes, air filter replacements, and fuel filter changes are essential to maintaining the health of your diesel engine. At KingFleet, we recommend that diesel engines have their oil changed every 5,000 miles, and the air and fuel filters should be replaced every 10,000 miles.

Common Diesel Engine Repairs

Even with proper maintenance, diesel engines can still experience issues. Some of the most common repairs that we see at KingFleet include:

Injector Replacement

Diesel injectors are responsible for delivering fuel to the engine. Over time, they can become clogged or wear out, which can cause poor fuel economy, reduced power, and increased emissions. At KingFleet, we have the tools and experience to test and replace diesel injectors, ensuring that your engine is running at its best.

Turbocharger Repair

Turbochargers are used to increase the amount of air entering the engine, increasing horsepower and torque. However, turbochargers can experience problems, such as worn bearings or clogged wastegates, which can lead to reduced performance. Our team at KingFleet is skilled in repairing and replacing turbochargers, to get your vehicle back to optimal performance.

EGR System Repair

The Exhaust Gas Recirculation (EGR) system helps reduce emissions by recirculating a portion of the engine's exhaust back into the air intake. However, the EGR system can become clogged or malfunction, which can cause issues such as reduced power and increased emissions. Our team at KingFleet has the expertise to diagnose and repair EGR system issues.
