Subaru Legacy BN/BS (2015-2019) Service Manual: Radiator cap inspection
1. Check that the radiator cap does not have deformation, cracks or damage. 2. Attach the radiator cap tester to radiator cap. 3. Check the maximum pressure while pumping the radiator cap tester several times. Replace the radiator cap if its valve opens at less than the service limit. CAUTION: • Be sure to remove foreign matter and rust from the cap in advance. Otherwise, results of pressure test will be incorrect. • For this inspection, tilt the radiator cap tester by at least 30°. NOTE: • Pumping interval is one second at a time. • If the radiator cap cannot retain the maximum pressure at times, this is not malfunction. Standard: 93 — 123 kPa (0.95 — 1.25 kg/cm2, 14 — 18 psi) Service limit: 83 kPa (0.85 kg/cm2, 12 psi)
