General Description
C: CAUTION
 Wear working clothing, including a cap, protec-
tive goggles, and protective shoes during opera-
tion.
 Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
 Keep the disassembled parts in order and pro-
tect them from dust or dirt.
 Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly, and replacement.
 Be careful not to burn yourself, because each
part in the vehicle is hot after running.
 Be sure to tighten fasteners including bolts and
nuts to the specified torque.
 Place shop jacks or rigid racks at the specified
points.
 Before disconnecting electrical connectors of
sensors or units, be sure to disconnect the ground
cable from battery.
 All parts should be thoroughly cleaned, paying
special attention to the engine oil passages, pis-
tons and bearings.
 Rotating parts and sliding parts such as piston,
bearing and gear should be coated with oil prior to
assembly.
 Be careful not to let oil, grease or coolant contact
the timing belt, clutch disc and flywheel.
 All removed parts, if to be reused, should be re-
installed in the original positions and directions.
 Bolts, nuts and washers should be replaced with
new ones as required.
 Even if necessary inspections have been made
in advance, proceed with assembly work while
making rechecks.
 Remove or install the engine in an area where
chain hoists, lifting devices, etc. are available for
ready use.
 Be sure not to damage coated surfaces of body
panels with tools or stain seats and windows with
coolant or oil. Place a cover over fenders, as re-
quired, for protection.
 Prior to starting work, prepare the following:
Service tools, clean cloth, containers to catch cool-
ant and oil, wire ropes, chain hoist, transmission
jacks, etc.
 Lift-up or lower the vehicle when necessary.
Make sure to support the correct positions.
