Turbocharger and Supercharger Inspection Checklist

This turbocharger and supercharger inspection checklist provides systematic assessment of forced induction system health. Turbocharger replacement costs $1,500-5,000. Most turbo failures result from neglected oil changes, improper cooldown procedures, or restricted oil supply - all preventable. Aligned with ASE A1/A8 certification, BorgWarner and Garrett turbocharger service guidelines, and OEM forced induction requirements.

Physical Turbocharger Condition

Inspect for bearing wear, blade damage, and oil seal failure.

  • Turbo shaft radial play within OEM limit - typically under 0.5-1.0mm?
  • Turbo shaft axial play within specification - typically 0.025-0.085mm?
  • Compressor wheel blades free from nicks, chips, or foreign object damage?
  • Turbine wheel free from heat cracking, erosion, or broken blades?
  • No oil past compressor or turbine seals - blue smoke under boost indicates seal failure?

Oil Supply and Cooling System

Oil supply is the life of the turbocharger.

  • Turbo oil supply line not kinked, restricted, or leaking?
  • Oil drain line clear - no clog or restriction causing oil back pressure past seals?
  • Turbo coolant supply and return lines connected and not leaking?
  • Engine oil at correct level and not overdue for change?
  • Correct low-viscosity synthetic oil in use - 0W-20 or 5W-30 as OEM specified?

Boost Pressure and Wastegate Testing

Verify boost levels and control components.

  • Peak boost pressure at full load within OEM specification per scan data?
  • Wastegate actuator moving freely - not seized open or closed?
  • All intercooler pipes and boots pressurized and checked for boost leaks?
  • Blow-off or compressor bypass valve cycling correctly at deceleration?
  • Intercooler free from oil accumulation and fins undamaged?

VGT and Supercharger Specific Checks

Specialized inspection for VGT and belt-driven superchargers.

  • VGT vanes cycling through full range via bi-directional scan tool command?
  • No VGT actuator or underboost/overboost fault codes?
  • Supercharger drive belt in good condition and tension within spec?
  • Supercharger gear housing oil level correct where applicable?
  • Supercharger bypass valve actuating correctly at cruise?

Cooldown Procedure Compliance and Documentation

Educate customer and document inspection findings.

  • Customer advised of 2-5 minute idle cooldown required after hard driving before shutdown?
  • Customer advised of shorter oil change interval for turbocharged engine - typically 5,000-7,500 miles synthetic?
  • Inspection documented with shaft play measurements, boost readings, and all findings?
  • Turbocharger replacement quote provided if shaft play or boost indicates impending failure?
  • Fresh oil change performed or recommended with turbocharger service?
  • Next turbocharger inspection interval scheduled in customer file?
