Garza & Sons Auto we specialize in providing top-tier services for diesel engines, ensuring your truck or powered vehicle achieves peak performance, reliability, and efficiency. Diesel engines are a unique breed, relying on compression ignition rather than a sparking plug as in gasoline engines. This higher compression process enables diesel engines to produce more power and durability. Our team is highly experienced in working with diesel fuel systems, fuel injection processes, and high-pressure combustion engines, making us the go-to diesel repair and performance shop in the area.

Fuel Injection System
Diesel engines rely heavily on a precise fuel injection system, where diesel fuel is injected directly into the combustion chamber under high pressure. Our technicians inspect fuel injectors, injection timing, and ensure the fuel mixture is optimized for performance.

Combustion Chamber Health
We analyze your combustion chamber and inspect the fuel injection process to confirm that engine compression is at the proper levels for maximum power output.

Exhaust and Emissions Testing
Diesel engines generate emissions such as nitrogen oxides. We perform checks and adjustments to minimize these emissions, maintaining both performance and environmental standards.
