MENT, Automatic Transmission Fluid.>

C: INSPECTION

1) Remove radiator cap, top off radiator, and attach

2) Apply a pressure of 157 kPa (1.6 kg/cm

, 23 psi)

to radiator to check if:

(1) Engine coolant leaks at/around radiator.
(2) Engine coolant leaks at/around hoses or
connections.

NOTE:
• Engine should be off.
• Wipe engine coolant from check points in ad-

RADIATOR CAP

8. 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:

93 — 123 kPa (0.95 — 1.25 kg/cm

, 14 — 18

psi)

Service limit pressure:

83 kPa (0.85 kg/cm

, 12 psi)

CAUTION:
Be sure to remove foreign matter and rust from
the cap in advance. Otherwise, results of pres-
