Perform routine preventive maintenance services including oil and filter changes, lube and grease jobs, fluid top-offs, coolant system inspections, and scheduled manufacturer maintenance items.
Inspect, remove, and install brake system components (pads, rotors, calipers, shoes) and perform brake system bleeding, basic ABS checks, and post-repair verification drives under supervision.
Mount, dismount, and balance tires; perform rotational patterns, inspect tire wear, change wheels, and verify proper lug torque to manufacturer specifications.
Assist in suspension and steering repairs by inspecting shocks, struts, control arms, tie rods, bushings, and steering linkages; replace components and perform safety checks after installation.
Support engine and transmission work by removing and installing components, assisting with gasket changes, basic tune-ups, fluid changes, and controlled disassembly/reassembly tasks under direction.
Troubleshoot and perform basic repairs on vehicle electrical systems including batteries, starters, alternators, wiring harnesses, lighting, sensors, fuses, and relays.
Use and maintain hand tools, pneumatic tools, lifts, hoists, jacks, and torque wrenches safely and accurately; ensure tools are calibrated and stored properly.
Perform exhaust system inspections and repairs including replacing mufflers, hangers, catalytic converters and patching or replacing piping as directed by senior staff.
