FAQs

What Are Some Common HVAC Issues?



Some common HVAC issues in diesel vehicles include a faulty compressor, leaking refrigerant, or clogged air filters. The compressor is a vital component of the HVAC system and is responsible for pressurizing the refrigerant and circulating it through the system. A faulty compressor can cause the entire HVAC system to malfunction, resulting in no or limited airflow and warm air inside the vehicle. Refrigerant leaks can occur in the HVAC system, leading to a decrease in the overall performance of the system and the inability to maintain a comfortable temperature inside the vehicle. Air filters play an important role in the HVAC system by trapping dirt, dust, and other debris that can damage the system and negatively impact the air quality inside the vehicle. If the air filters become clogged, it can restrict airflow and reduce the efficiency of the HVAC system.

What Are Some Common Liftgate Issues in Diesel Vehicles?



One of the most common issues that diesel vehicle owners experience with their liftgates is a malfunctioning electric motor. This can occur due to a variety of reasons, such as a worn-out motor or a malfunctioning switch. In such cases, our mechanics at KingFleet will diagnose the problem and replace the faulty component, ensuring that your liftgate is working properly again.

Another common issue with liftgates is a malfunctioning hydraulic system. The hydraulic system is responsible for lifting and lowering the cargo bed, and a malfunction can cause the liftgate to become stuck in the open or closed position. Our mechanics will inspect the hydraulic system, including the cylinders, hoses, and fluid levels, to identify and repair any issues.

What is a DOT Inspection?



A DOT inspection is a comprehensive examination of a commercial vehicle that is performed by a certified inspector to ensure it is safe to operate on public roads. The inspection covers a wide range of components, including the vehicle's braking system, steering, suspension, lighting, and tires. It also includes a check of the vehicle's overall condition, including any visible signs of wear or damage.

Why Is Coolant System Maintenance So Important?



Regular maintenance of the coolant system is crucial to the longevity and performance of the engine. It is recommended that the coolant be changed every 2 years or 30,000 miles, whichever comes first. Old coolant can become contaminated with rust and debris, which can clog the coolant passages and reduce the efficiency of the system. A fresh coolant flush can help remove these contaminants and ensure that the coolant is able to flow freely through the engine.

Another important aspect of coolant system maintenance is checking the integrity of the hoses and connections. Over time, the hoses can become brittle and develop leaks, which can lead to a loss of coolant and potential engine damage. The connections should also be checked for leaks and tightened if necessary.

Why Is Preventive Maintenance Important for Diesel Vehicles?



Diesel engines are known for their durability and long lifespan. However, they do require regular maintenance to keep them running at their best. Preventive maintenance helps to prevent breakdowns and costly repairs in the future. It also helps to improve fuel efficiency and extend the life of the vehicle.
