1996 SUBARU LEGACY radiator cap

G2M0223
5. Radiator Cap
A: INSPECTION
1) Attach radiator cap to 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 seconds.
Standard pressure:
78—98 kPa (0.8—1.0 kg/cm
2,11—14 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 pressure test will be
incorrect.

A: REMOVAL
1) Disconnect ground cable from battery terminal.
2) Disconnect connector of fan motor.
G2M0224
3) Remove reservoir tank.

3) Disconnect the connection between the expansion
valve and pipe from receiver drier.
4) Remove the expansion valve from pipes.
5) To install expansion valve, reverse removal procedures.
Properly wrap capillary tube of expansion valve with seal.
6) Check to see if the evaporator fins are clogged. If they
are, clean them with compressed air.
CAUTION:
Water must never be used to clean the evaporator.
7) Check parts that have been removed for cracks or
scratches, and repair or replace them with new ones, if
necessary.
8) Reassemble the evaporator in the reverse order of dis-
assembly.
NOTE:
Confirm that the O-ring is inserted in the specified position.
