Filing in context
This notification is a joint filing by 3 manufacturers: Hino, Isuzu & UD Trucks.
The Cooling System is the most frequently cited component category in this archive, appearing in 34 of its 4,890 filings. This filing is one of 28 Hino notifications from 2022 in this archive. For scale, 1,601 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 1 year and 3 months.
Defect
On large trucks, insufficient strength in the plastic radiator upper tank allows cracks to initiate from the tank surface ribs during service, causing coolant to leak. If the vehicle continues to be operated in this condition, a low-coolant warning message and buzzer alert will activate.
Corrective action
Replace the radiator assembly on all vehicles with a revised part made from an updated material. If a sub-tank cap rated at 1.2 kgf/cm² is installed, replace it with the 0.95 kgf/cm² type.

状況
大型トラックの冷却装置において、樹脂製ラジエータの強度が不足しているため、使用過程においてアッパータンク表面のリブ（突起状の物）を起点に亀裂が入り、冷却水が漏れるおそれがある。そのままの状態で使用を続けると、冷却水量低下の警告メッセージ表示及びブザーが吹鳴する。
改善措置
全車両、ラジエータアセンブリを材質変更した対策品に交換する。また、サブタンクキャップが１．２ｋｇｆ／ｃｍ２のタイプが装着されている場合は、０．９５ｋｇｆ／ｃｍ２のタイプに交換する。
