2. INSPECT RADIATOR CAP
NOTICE: When performing steps (a) and (b) below, keep
the radiator pump tester at an angle of over 30
above
the horizontal.
(a) Using a radiator cap tester, slowly pump the tester
and check that air is coming from the relief valve.
Pump speed:
1 push/3 seconds or more
NOTICE: Push the pump at a constant speed.
If air is not coming from the relief valve, replace the
radiator cap.
(b) Pump the tester several times and measure the relief
valve opening pressure.
Pump speed:
1 at time
1 push/1 second or less
2nd time or more
Any speed
Standard opening pressure:
83 – 113 kPa
(0.85 – 1.15 kgf/cm
2
, 12.1 – 16.4 psi)
Minimum opening pressure:
69 kPa (0.7 kgf/cm
2
, 10.0 psi)
If the opening pressure is less than minimum, replace
the radiator cap.
RADIATOR
RADIATOR CLEANING
Using water or a steam cleaner, remove any mud and
dirt from the radiator core.
NOTICE: If using a high pressure type cleaner, be careful
not to deform the fins of the radiator core. If the cleaner
nozzle pressure is 2,942 – 3,432 kPa (30 – 35 kgf/cm
2
,
427 – 498 psi), keep a distance of at least 40 cm (15.75
in.) between the radiator core and cleaner nozzle.
RADIATOR INSPECTION
1. REMOVE RADIATOR CAP FROM WATER OUTLET
CAUTION: To avoid the danger of being burned, do not
remove the radiator cap while the engine and radiator are
still hot, as fluid and steam can be blown out under
pressure.
