SERVICE POINTS OF REMOVALNO7lBAC311. DISCONNECTION OF POWER STEERING OIL PUMP
Disconnect the oil pump with hoses from the bracket.
NOTEThe removed power steering oil pump should be fastened
(by using rope, etc.) in a position that will not interfere with
the removal/installation of the engine assembly.
27. REMOVAL OF TURBOCHARGER ASSEMBLY
Remove the turbocharger assembly with the exhaust
fitting, water pipe A, water pipe
B and the oil pipe attached
to it.
38. DISCONNECTION OF RADIATOR LOWER HOSE
After making mating marks on the radiator hose and the
hose clamp, disconnect the radiator hose.
INSPECTIONN07lCAAa3WATER PIPE AND HOSE INSPECTION
Check the water pipe and hose for cracks, damage, clog and
replace them if necessary.
SERVICE POINTS OF INSTALLATION
N071DAJ345. INSTALLATION OF
0-RING/44. WATER INLET PIPE
Insert the O-ring to the water inlet pipe, and coat the outer
circumference of the O-ring with water.
By coating with water, the insertion to the water pump will
become easier.
Caution
Care must be taken not to permit engine oil or other
greases to adhere to the O-ring.
38. CONNECTION OF RADIATOR LOWER HOSE
Align the mating marks on the radiator hose and hose
clamp and then connect them; then, applying force in the
direction indicated by the arrow in the illustration, seat the
clamp to the trace marks of the previous connection.
Caution
Be sure to install the hose clamps at the trace marks ofthe previous connection.

05K55734. INSTALLATION OF WATER HOSE
Install the water hose with the longer straight area
positioned on the turbo side.
27. INSTALLATION OF TURBOCHAGER ASSEMBLY
Clean the alignment surfaces shown in the illustration.
Caution
When cleaning, care must be taken so that a piece of
the gasket does not enter the oil passage hole.
18. INSTALLATION OF WATER PIPE
(B)Before installing to the water inlet pipe, apply machine oil to
the inner surface of the pipe flare.
