For removal of the engine from the vehicle, installation of the engine in the vehicle, and on-vehicle inspection and service of 
the engine, please use the separate Workshop Manuals prepared for the vehicle.

(1) A component part drawing is shown at the beginning of each section to enable the technician to ascertain the installed con-
     dition of the component parts.
(2) Service steps are indicated by means of numbers in the component part drawing. Non-reusable parts are indicated as such, 
     and tightening torques are shown.
    ·Removal steps
     The numbers of the part names match the numbers in the component part drawing and indicate the removal sequence.
    ·Installation steps
     Installation steps are omitted wherever installation can be achieved simply by performing the removal steps in reverse.
    ·Disassembly steps
     The numbers of the part names match the numbers in the component part drawing and indicate the disassembly sequence.
    ·Reassembly steps
     Reassembly steps are omitted wherever reassembly can be achieved simply by performing the disassembly steps in reverse.
