Diesel Repair and Maintenance

Diesel is a popular choice for commercial vehicles, and for good reason. While gasoline generally produces higher horsepower, diesel produces higher torque, which makes it ideal for towing and transporting.

Diesel engines use compression systems instead of spark plugs to ignite fuel. Diesel requires higher temperatures to burn fuel, but the fuel burns slower, which results in increased fuel economy.

Compared to gasoline engines, diesel engines offer remarkable longevity and low maintenance. Repairs can be time and labor-intensive, but diesel systems generally last longer than gasoline.

However, it can be difficult to find qualified technicians and parts for your diesel vehicle. That is where the reliable experts at OnSite Fleet Services of Texas come in. With an attention to detail and an efficiency of service, we will treat your diesel vehicle as if it was our own.

We will inspect, repair, and maintain any truck’s diesel engine. A typical repair job consists of oil changes, cleaning the fuel filter, and changing the fuel and air filter.

Cleaning the fuel filter is particularly important because over time dirt can clog a diesel system, necessitating costly repairs.

We also offer the highest quality belts, hoses, and gaskets for replacement in your diesel system. We also quickly eliminate cooling system leaks.
