Identify engine block heater(s).
Inspect turbocharger(s), wastegate(s), piping systems, intake manifold, gaskets, connections, engine exhaust system, exhaust gas recirculation (EGR) system, crankcase ventilation system, and exhaust aftertreatment system for leaks, mounting, proper routing, and damaged or missing components, and service as needed.
Check the air induction system, replace the air filter as needed, and reset the restriction indicator (if applicable).
Examples: cooler assembly, piping, hoses, clamps, mountings
Check and report on fuel level and condition.
Inspect low-pressure and high-pressure fuel system components including fuel tanks, fuel pump, pump drives, screens, fuel/water separators/indicators, hold-downs, filters, heaters, coolers, ECM cooling plates, crossover system, fittings, seals, mounting hardware, vents, caps, valves, screens, hoses, lines, check valves, pressure regulator valves, and restrictive fittings.
Replace fuel filter and prime and bleed fuel system.
Inspect engine compression and exhaust brake housing, valves, seals, lines, and fittings.
Identify heating, ventilation, and air conditioning (HVAC) components and configuration.
Use appropriate HVAC electronic service tools and procedures to check, record, and clear diagnostic codes, and interpret digital multimeter (DMM) readings.
Inspect A/C compressor drive belts, pulleys, and tensioners and verify proper belt alignment, and check A/C condenser for airflow restrictions to determine needed action.
Check A/C system operation including system pressures, visually inspect A/C components for signs of leaks, and check A/C monitoring system (if applicable).
Inspect engine cooling system and heater system hoses and pipes, HVAC system-heater ducts, doors, hoses, cabin filters, and outlets and determine needed action.
Identify the source of A/C system odors.
Examples: cabin air filters, restricted drains, foreign items
