MORE DETAIL
A CLOSER LOOK AT WHAT WE DO.
A FEW EXAMPLES OF THE MAINTENANCE, REPAIR, DIAGNOSTIC, AND CUSTOM-BUILD WORK WE HANDLE FOR BOTH GAS AND DIESEL VEHICLES.
01 / ENGINE MAINTENANCE
ENGINE MAINTENANCE FOR GAS & DIESEL VEHICLES
Maintenance for gas and diesel vehicles is based on mileage, operating conditions, and how the vehicle is used.
- Oil and filter services, air and fuel filters, spark plugs, belts, hoses, and fluid inspections
- Coolant, transmission, differential, and transfer-case services when applicable
- Maintenance planning for daily drivers, work trucks, tow vehicles, and high-mileage vehicles
02 / ENGINE REPAIR
DIAGNOSED ENGINE REPAIR—NOT GUESSWORK
Engine repairs are based on inspection and test results so the repair addresses the actual failure.
- Oil and coolant leaks, gaskets and seals, water pumps, thermostats, radiators, and cooling-system repairs
- Misfires, overheating, low power, unusual noises, and mechanical condition testing
- Timing components, engine accessories, and related fuel or air-delivery repairs for gas and diesel engines
03 / SUSPENSION & STEERING REPAIR
GENERAL SUSPENSION, STEERING, AND RIDE-CONTROL REPAIR
We inspect the complete steering and suspension system to identify the source of handling, noise, and tire-wear concerns.
- Shocks, struts, springs, control arms, ball joints, tie rods, bushings, and wheel bearings
- Steering racks, pumps, hoses, and related steering-system repairs
- Diagnosis for clunks, wandering, vibration, uneven tire wear, and poor ride quality
04 / A/C & COOLING PERFORMANCE
A/C SERVICE, LEAK TESTING, AND COOLING PERFORMANCE DIAGNOSIS
A/C and cooling-system concerns are tested before parts are recommended.
- Refrigerant leak detection, evacuate and recharge service, compressors, condensers, hoses, and related components
- Weak airflow, blower-motor, control, and temperature-management concerns
- Radiators, water pumps, thermostats, cooling fans, coolant leaks, and overheating diagnosis
05 / ELECTRICAL DIAGNOSIS
ELECTRICAL TESTING FOR MODERN VEHICLE SYSTEMS
Electrical faults are traced with scan data and circuit testing instead of replacing parts based only on a fault code.
- No-start, battery, alternator, starter, charging-system, and parasitic-draw concerns
- Warning lights, module communication faults, sensor circuits, shorts, opens, and voltage-drop issues
- Intermittent wiring and connector problems on gas and diesel vehicles
06 / DIESEL DIAGNOSIS & REPAIR
DIESEL-SPECIFIC TESTING, REPAIR, AND PERFORMANCE DIAGNOSIS
Diesel diagnosis focuses on the fuel, air, boost, emissions, and electrical systems that affect performance and reliability.
- Hard starting, low power, smoke, rough running, overheating, and drivability concerns
- Fuel delivery, injectors, turbocharger and boost-control systems, EGR, DPF, SCR, and DEF faults
- Forced regeneration, emissions diagnosis, and repairs for diesel daily drivers, tow vehicles, and work trucks
07 / CUSTOM BUILDS
CUSTOM OFF-ROAD, SUSPENSION & OVERLAND BUILDS
Off-road and overland systems are selected around the vehicle, terrain, load, and intended use.
- Suspension systems for general overlanding, long-travel rock-crawling setups, and high-speed off-road use
- Wheel and tire fitment, steering and suspension geometry, bump stops, and clearance corrections
- Battery-management systems, auxiliary power, lighting, onboard air, and charging upgrades
- Winches, bumpers, recovery points, skid plates, rock sliders, racks, and recovery gear
