Caution
•
Applying more than 123 kPa {1.25 kgf/cm2,
17.8 psi} can damage the hoses, fittings, and
other components, and cause leaks.
4. Apply pressure to the radiator.
Pressure
123 kPa {1.25 kgf/cm2, 17.8 psi}
5. Verify that the pressure is held. If not, inspect the
system for coolant leakage.
RADIATOR CAP INSPECTION
1. Attach the radiator cap to a radiator cap tester
with the SST. Apply pressure gradually.

specification.
Pressure
94— 122 kPa
{0.95— 1.25 kgf/cm2, 13.5— 17.7 psi}
3. If the pressure is held for 10 seconds, the radiator
