How Our Process Works

When you bring your truck in for engine repair or replacement in Midland, we start with a thorough teardown and inspection to determine which components can be salvaged and which need replacing. Our certified mechanics measure tolerances, check cylinder walls, inspect bearings, and evaluate crankshaft condition. This ensures we only replace what's necessary and rebuild to manufacturer specifications.


Lonewolf Diesel uses high-quality parts sourced from trusted suppliers, and every assembly follows proper torque specifications to avoid future failures. We perform internal engine repairs with dealership-quality precision. Fast turnaround is a priority because we understand that downtime costs you money, especially in Midland's oilfield and transportation industries.


After reassembly, we test the engine under load conditions to verify oil pressure, coolant flow, compression, and overall performance. You'll get a rebuilt or replaced engine that runs as reliably as it did when new, backed by our commitment to quality workmanship and attention to detail.
