1999 SUBARU LEGACY radiator cap

C: CHECKING OF COOLING
SYSTEM
1) Remove radiator cap, top off radiator, and
attach tester to radiator in place of cap.
B2M0136
2) Apply a pressure of 157 kPa (1.6 kg/cm2,23
psi) to radiator to check if:
(1) Engine coolant leaks at/around radiator.
(2) Engine coolant leaks at/around hoses or
connections.
CAUTION:
IEngine should be off.
IWipe engine coolant from check points in
advance.
IBe careful to prevent engine coolant from
spurting out when removing tester.
IBe careful also not to deform filler neck of
radiator when installing or removing tester.

2) Increase pressure until tester gauge pointer
stops. Radiator cap is functioning properly if it
holds the service limit pressure for five to six sec-
onds.
Standard pressure:
78 Ð 98 kPa (0.8 Ð 1.0 kg/cm2,11Ð14
psi)
Service limit pressure:
69 kPa (0.7 kg/cm
2, 10 psi)
CAUTION:
Be sure to remove foreign matter and rust from
the cap in advance; otherwise, results of pres-
sure test will be incorrect.
