Keep a distance more than 40 — 50 cm (15.75 — 19.69 in.) between the radiator core and cleaner nozzle when the cleaner nozzle pressure is 30 — 35 kg/cm² (427 — 498 psi, 2,942 — 3,432 kPa).\n\nINSPECTION OF RADIATOR\n\n1. CHECK RADIATOR CAP\nUsing a pressure tester, pump the tester until the relief valve opens.\nNotice that valve opens between 0.75 to 1.05 kg/cm² (10.7 psi, 74 kPa) and 1.05 kg/cm² (15 psi, 103 kPa).\nCheck that the pressure gauge does not drop rapidly when pressure on cap goes below 0.6 kg/cm² (8.5 psi, 59 kPa).\nIf either check is not within limits, replace cap.\n\n2. CHECK COOLING SYSTEM FOR LEAKS\n(a) Fill the radiator with coolant and attach a pressure tester.\n(b) Warm up the engine.\n(c) Pump it to 1.2 kg/cm² (17.1 psi, 118 kPa), check that pressure does not drop.\nIf the pressure drops, check for leaks from hoses, radiator or water pump. If no external leaks are found, check the heater core, block and intake manifold.","image":"https://tsrm.sasquatchvc.com/images/mk2/CO/CO_007.png","url":"https://tsrm.sasquatchvc.com/mk2/tsrm/CO/7","prev":{"page":6,"url":"https://tsrm.sasquatchvc.com/mk2/tsrm/CO/6","api":"https://tsrm.sasquatchvc.com/api/pages/mk2/tsrm/CO/6"},"next":null,"section_url":"https://tsrm.sasquatchvc.com/mk2/tsrm/CO","section_api_pages":["https://tsrm.sasquatchvc.com/api/pages/mk2/tsrm/CO/1","https://tsrm.sasquatchvc.com/api/pages/mk2/tsrm/CO/2","https://tsrm.sasquatchvc.com/api/pages/mk2/tsrm/CO/3","https://tsrm.sasquatchvc.com/api/pages/mk2/tsrm/CO/4","https://tsrm.sasquatchvc.com/api/pages/mk2/tsrm/CO/5","https://tsrm.sasquatchvc.com/api/pages/mk2/tsrm/CO/6","https://tsrm.sasquatchvc.com/api/pages/mk2/tsrm/CO/7"],"note":"OCR transcript of a scanned Toyota factory manual page; verify critical values (torque specs, part numbers) against the image."}
