CAUTION
As there will be some pressure remaining in the fuel pipe
line, cover it with a shop towel to prevent fuel from spray-
ing out.
2. Press the high-pressure fuel hose retainer to disengage the
connector, and then remove the high-pressure fuel hose.
3. Hold the fuel filter with an adjustable wrench and loosen the
flare nut. Then disconnect the main pipe connection.
4. Remove the fuel filter.
5. Install the fuel filter, high-pressure fuel hose and tighten the
flare nut of the main pipe to the specified torque.
Tightening torque: 37 N
⋅m (27 ft-lb)
6. After installation, check that there are no fuel leaks.
(1) Apply battery to the fuel pump drive terminal to operate
the fuel pump. (Refer to GROUP 13A, On-vehicle Service
(2) Check for leaks when fuel pressure is applied.

ENGINE COOLING

GENERAL DESCRIPTION
M1141000100263
The cooling system is designed to keep every part of
the engine at appropriate temperature in whatever
condition the engine may be operated. The cooling
method is of the water-cooled, pressure forced circu-
lation type in which the water pump pressurizes cool-
ant and circulates it throughout the engine. If the
coolant temperature exceeds the prescribed temper-
ature, the thermostat opens to circulate the coolant
through the radiator as well so that the heat
absorbed by the coolant may be radiated into the air.
The water pump is of the centrifugal type and is
driven by the drive belt from the crankshaft. The radi-
ator is the corrugated fin, down flow type and is
cooled by the cooling fan.

ENGINE COOLING DIAGNOSIS
INTRODUCTION
M1141005300251
The system cools the engine so that it does not over-
heat and maintains the engine at an optimum tem-
perature. The system components are the radiator,
water pump, thermostat, cooling fan and fan clutch
assembly. Possible faults include low coolant, con-
tamination, belt loosening and component damage.
TROUBLESHOOTING STRATEGY
M1141005200254
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure to find
most of the engine cooling faults.
1. Gather information from the customer.
2. Verify that the condition described by the
customer exists.
3. Find the malfunction by following the SYMPTOM
CHART.
4. Verify that the malfunction is eliminated.
