INSPECTION
RADIATOR
• Visually inspect the radiators and hose for damage.
• Fins bent down or dented can be repaired by straightening
them with the blade of a small screwdriver.
RADIATOR CAP
• Fit the cap to the radiator cap tester.
• Build up pressure slowly by operating the tester. Make sure
that the pressure build-up stops at 95 – 125 kPa (0.95 – 1.25
kgf/cm
2
, 14 – 18 psi) and that, with the tester held standstill,
the cap is capable of holding that pressure for at least 10 sec-
onds.
• Replace the cap if it is found not to satisfy either of these two
requirements.
