   NOTICE
   If the turbine housing must be rotated to remove the turbocharger, loosen the V-band clamp only enough to allow for rotation (typically 7-10 turns). If the V-band clamp is loosened excessively, the housing may contact the turbine wheel and cause damage. Contact with the housing may cause rapid wear and shorten turbocharger life.
