2. There should be continuity when the float is 

raised, while there is no continuity when it is 
lowered.

3. Replace the fuel filter assembly if it is faulty.

FUEL FILTER VACUUM SWITCH CHECK

ACB01916AB

1. Connect the circuit tester to the fuel filter vacuum 

switch and check to see that there is continuity 
between the terminals.

2. Replace the fuel filter assembly if it is faulty.

GENERAL INFORMATION

M1141000101824

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, cross-flow type.

ENGINE COOLANT LEAK CHECK

M1141001000515

WARNING

When pressure testing the cooling system, 
slowly release cooling system pressure to 
avoid getting burned by hot coolant.

CAUTION

• Be sure to completely clean away any mois-

ture from the places checked.

• When the tester is taken out, be careful not to 

spill any coolant.

Be careful when installing and removing the 
tester and when testing not to deform the 
filler neck of the radiator.

1. Check that the coolant level is up to the filler neck. 

Install a radiator tester and apply 160 kPa 
pressure, and then check for leakage from the 
radiator hose or connections.

2. If there is leakage, repair or replace the 

appropriate part.

NOTE: Be sure that the cap is clean before test-
ing. Rust or other foreign material on the cap seal 
will cause an improper reading.

Cap adapter

1. Use a cap adapter to attach the cap to the tester.
2. Increase the pressure until the indicator of the 

gauge stops moving.
Minimum limit: 83 kPa
Standard value: 93 

− 123 kPa

3. Replace the radiator cap if the reading does not 

remain at or above the limit.
