Perform complete engine repairs and rebuilds, including removal and installation of cylinder heads, timing systems, valve trains, fuel and ignition systems, and ensure proper torque, clearances, and calibration to OEM specifications.
Service and repair transmission and driveline systems, including automatic and manual transmissions, clutch assemblies, differentials, transfer cases, and perform road tests to validate shift quality and driveline noise resolution.
Inspect, diagnose, and repair braking systems (hydraulic systems, ABS modules, rotors, pads, calipers), including bleed procedures, sensor replacement, and ABS fault code elimination to ensure vehicle safety and compliance.
Perform scheduled preventive maintenance services (oil changes, filter replacements, tire rotations, fluid exchanges), and execute multi-point inspections to identify potential issues and recommend proactive repairs that reduce downtime and cost.
Troubleshoot and repair HVAC and climate control systems, including compressors, condensers, evaporators, blower motors, blend doors, and perform EPA-compliant refrigerant recovery/recharge procedures.
Conduct thorough electrical and electronic system repairs: wiring harness diagnostics, module replacement (ECM/TCM/BCM), sensor replacement, grounds and connector repairs, and software updates using OEM reflash tools.
Carry out suspension and steering repairs and alignments (struts, shocks, ball joints, tie rods, control arms), identify worn components, and restore proper vehicle handling, steering geometry, and ride comfort.
Perform emissions system diagnostics and repairs (catalytic converters, EGR systems, oxygen sensors), use emission test equipment and documentation to ensure vehicles meet federal and state regulations.
Execute precise diagnostic road tests and post-repair validation procedures, documenting observations, repair steps taken, and final outcomes in the shop management system to support warranty and customer communications.
Safely operate vehicle lifts, jacks, and hoists to access undercarriage components, adhering to manufacturer weight limits, lockout/tagout procedures, and shop safety protocols to prevent injuries and equipment damage.
Provide accurate written and verbal cost estimates, explain repair needs and options to customers and service advisors in plain language, and obtain required approvals before beginning work.
Order, track and verify parts and supplies, cross-reference OEM and aftermarket part numbers, and inspect incoming parts to ensure compatibility and quality before installation.
Follow manufacturer service procedures and maintenance schedules, use factory service manuals and technical service bulletins (TSBs) to perform warranty repairs and to ensure repairs meet or exceed OEM standards.
Maintain detailed records of labor, materials, replaced parts, and diagnostic trouble codes in the shop management system to support invoicing, warranties, and fleet maintenance histories.
Perform battery testing, charging system diagnostics, starter repairs/replacement, and maintain proper battery handling and disposal procedures to prevent hazards and ensure vehicle reliability.
Work with hybrid and electric vehicle systems as assigned: high-voltage system isolation, battery pack diagnostics, inverter and motor troubleshooting, following OEM safety protocols and using insulated PPE and specialized tools.
Calibrate and verify ADAS components (cameras, radar, lane departure systems) after windshield replacement, sensor replacement or structural work, using OEM calibration procedures and alignment rigs to ensure proper system function.
Mentor and train junior technicians and apprentices, provide hands-on guidance, enforce quality standards, and contribute to a continuous-improvement culture in the shop.
Maintain shop cleanliness and organization, follow hazardous materials handling and disposal procedures (refrigerants, oils, solvents), and contribute to a safe, efficient workshop environment that meets OSHA and EPA requirements.
Participate in technical training and certification programs to remain current with evolving vehicle systems, diagnostic techniques, and industry best practices.

Secondary Functions

Assist service advisors with customer intake inspections and formulate clear vehicle condition reports with photographic evidence to support repair recommendations.
Help manage parts inventory levels, flag slow-moving or critical parts and collaborate with parts personnel to improve parts availability and reduce repair wait times.
Support ad-hoc fleet maintenance projects, including preventive maintenance scheduling for company or client fleets, and contribute progress updates to fleet managers.
Contribute to the development of shop procedures and KPI tracking (turnaround time, comebacks, productivity), offering insights from the technician perspective to improve workflow.
Aid in after-hours emergency repairs or callback support as needed, ensuring high-priority vehicles are returned to service quickly and safely.
Participate in service meetings, safety briefings, and quality reviews to provide technical feedback and collaboratively reduce recurring issues.
Cross-train on specialty shop tasks such as tire mounting/balancing, windshield replacement, or basic body repair to increase team flexibility.
Support warranty claim submissions by compiling repair documentation, diagnostics logs, and photographs required by manufacturers and submit within warranty timeframes.
Assist in implementing digital inspection and communication tools (tablet inspections, customer-facing reports) to improve transparency and upsell acceptance.
Help maintain service equipment calibration (tire machines, wheel balancers, diagnostic interfaces) and schedule vendor maintenance when needed.
