balance again. Check that wheel balance is cor-
rectly adjusted.
NOTE:
Knock-on type balance weights for aluminum
wheels are available for use with any 15 to 18 inch
wheels.
Service limit:
Knock-on type weight for aluminum wheels:
5—25 g (0.18—0.88 oz) 5.0 mm (0.20 in)

Radiator Cap
COOLING
7. Radiator Cap
A: INSPECTION
1) Attach the radiator cap to tester.
2) Increase pressure until the tester gauge pointer
stops. Radiator cap is functioning properly if it holds
the service limit pressure for five - six seconds.
Specified pressure:
93 — 123 kPa (0.95 — 1.25 kg/cm2, 14 — 18
psi)
Service limit pressure:
83 kPa (0.85 kg/cm2, 12 psi)
CAUTION:
Be sure to remove foreign matter and rust from
the cap in advance. Otherwise, results of pres-
sure test will be incorrect.
