Cooling System

PERIODIC MAINTENANCE SERVICES

10.Cooling System

A: INSPECTION

1) To check the radiator for leakage, fill it with en-
gine coolant, and attach the radiator cap tester (A)
to the filler neck, and apply pressure. Check the fol-
lowing points:

Non-turbo model:

157 kPa (1.6 kg/cm

2

, 23 psi)

Turbo model:

122 kPa (1.2 kg/cm

2

, 18 psi)

• Each portion of radiator for leakage
• Hose joints and other connections for leakage

NOTE:
• For turbo model, be sure to install the tester to
filler tank side.
• Be particularly careful not to deform the filler
neck of radiator when installing and removing the
tester and after testing.

• Non-turbo model

• Turbo model

• When performing this check, be sure to keep the
engine stationary and fill radiator with coolant.
• Wipe off check points before applying pressure.
• Use care not to spill coolant when detaching
tester from radiator.
• Do not remove the radiator side cap. (Turbo
model)

2) Check the radiator cap valve open pressure us-
ing radiator cap tester.

NOTE:
Rust or dirt on the cap may prevent valve from func-
tioning normally: be sure to clean the cap before
testing.
Raise the pressure until the needle of gauge stops
and see if the pressure can be retained for five to
six seconds. Replace the radiator cap if it is opened
under a pressure less than the service limit value
for this period.
