Periodic cleaning is recommended for the turbocharger compressor (inlet side). The following items collect in the turbocharger compressor housing since the fumes from the crankcase travel through the inlet air: oil, by-products from oil and by-products from combustion. The buildup reduces boost and air flow. The buildup also contributes to loss of engine power, increased black smoke, and overall loss of engine efficiency.

Cleaning and Inspecting

1. Remove the air inlet piping from the turbocharger and remove the compressor housing from the turbocharger.

2. Clean the turbocharger compressor housing with Hydrosolv Liquid Cleaners and a hard bristle brush.

3. Clean the turbocharger compressor wheel and clean the backplate assembly with 4C-4079 Brake and Electric Cleaner.
