Turbocharger Components

S6JB0A1436056

CAUTION

!

Before starting engine (including when performing oil level check and air bleeding process of cooling
system) for the first time after installing turbocharger, be sure to lubricate turbocharger, referring to
“CAUTION” in “Installation” under “Turbocharger Assembly Removal and Installation”. Otherwise,
lack of lubrication will cause turbocharger damage.
