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.
