Not every breakdown fits one category. Belts, hoses, cooling leaks, DOT lighting, exhaust, basic diagnostics — if it can be safely done roadside or on-site, we do it. Based in Hutto TX, we cover Austin and 30 miles around, 24 hours a day.
A truck behaving abnormally should always be investigated before continuing to drive. These symptoms warrant an immediate call.
Check engine or MIL light on the dashboard
Engine overheating warning — temperature gauge in red
Belt squealing or slipping sound from the engine bay
Coolant puddle under the truck after parking
DOT marker or brake lights not functioning
Exhaust leak — smell of exhaust in the cab
Engine running rough or with reduced power
Overheating is one of the most common roadside failures in Texas summer heat. We diagnose cooling system issues including coolant leaks at hoses, clamps and fittings, thermostat failure, water pump leaks and low coolant from evaporation or a small ongoing leak.
Fan belts, serpentine belts and accessory drive belts fail from age and heat. We carry belt assortments for common truck applications and replace broken or glazed belts on-site. Upper and lower radiator hoses and heater hoses are replaced when accessible without shop equipment.
Do Not Ignore Overheating: Running a diesel engine when it is overheating causes head gasket failure and piston damage in minutes. If the temperature gauge enters the red zone, shut down immediately and call us. The repair cost of a proper cooling service is a fraction of an engine rebuild.
A failed brake light, clearance light or marker light is an immediate DOT Out of Service violation. We carry LED replacement lights for the most common semi truck and trailer configurations and restore DOT lighting compliance on-site.
We carry diagnostic scan tools that communicate with J1939/CAN bus systems on Cummins, Detroit, PACCAR, Volvo, Mack and Navistar engine platforms. Fault code reading is often the first step in diagnosing unusual engine behavior — warning lights, derates and reduced power conditions. We read the codes, explain what they mean and advise on the fastest resolution.
