ENGINE COOLING – WATER HOSE AND PIPE14-4
Removal guidelines
A
Removing the radiator upper hose and the radiator
lower hose
Mark the radiator hose and the hose clamp with indicator marks
and then remove the radiator hose.
Fitting guidelines
A
Fitting the O-ring and the water inlet pipe
Fit the O-ring into the groove at the end of the water inlet pipe, and
insert it after moistening with water the places where the O-ring and
the water inlet pipe will be in contact.
Caution
Ensure that absolutely no engine oil, or other type of grease,
gets onto the O-ring.
B
Connecting the radiator lower hose and the radiator
upper hose
1. Insert the hose as far as the protrusion on the water inlet pipe
and the water outlet fitting.
2. Match up the indicator marks on the radiator hose and the hose
clamp, and fit the radiator hose.

Removal guidelines
A
Removal of the delivery pipe, the injector and the fuel
pressure regulator ASSY
Remove the deliver pipe, with the injector and the fuel pressure
regulator intact.
Caution
When removing the delivery pipe, be careful not to drop the
injector.
Fitting guidelines
A
Connecting the O-ring and the fuel high pressure hose
1. Apply a small quantity of fresh engine oil to the O-ring, and
insert it into the delivery pipe without damaging the O-ring.
2. Check that the high pressure hose can be turned smoothly. If it
cannot be turned smoothly there is a possibility that it is biting
into the O-ring, so remove the high pressure hose and check for
any damage to the O-ring. If the O-ring is undamaged, reinsert it
into the delivery pipe and check once more whether the hose
can be turned smoothly.
3. Tighten the mounting bolt to the specified torque.
Tightening torque: 5.0 ± 1.0 N·m
