Turbocharger System Diagnostics Guide

Complete a diagnostic check before you replace your turbo


Turbo Knowledge Base

High temperature, high-pressure exhaust gases from the engine enter the turbine housing and drive the turbine wheel. The turbine wheel is connected to the compressor wheel with a solid shaft. The rotation of the compressor wheel compresses the ambient air and forces it into the engine. This increases the amount of fuel that can be burnt, increasing the efficiency and power output of the engine.


Turbocharger System Check

  • The evaluation may only be conducted with the vehicle in a drivable condition.
  • The instructions are followed without fail as described by the vehicle manufacturers before any vehicle trials.
  • Discontinue the trials at signs of engine malfunction such as black smoke, excessive oil consumption or run away engine.
  • Always use the diagnosis tool recommended or provided by the vehicle’s manufacturer in combination with turbocharger guidelines.
Perform all checks on turbocharger and engine only when engine is not running and cold.
