Filing in context
This notification is a joint filing by 2 manufacturers: Mitsubishi & UD Trucks.
This filing is one of 80 Mitsubishi notifications from 2013 in this archive. For scale, 2,914 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 9 months.
Defect
On large buses, insufficient clamping force on the heater hose retaining clamps allows coolant flowing inside the heater hose to enter at the hose end, where it breaks down the hose's reinforcing threads. Continued use in this condition reduces hose strength until the hose can no longer withstand internal coolant pressure. The hose then ruptures and leaks coolant, degrading defroster performance and potentially obscuring the driver's forward field of vision through the windshield.
Corrective action
On all vehicles, replace the heater hoses and retaining clamps at locations with insufficient clamping force with corrected parts.

状況
大型バスにおいて、ヒータホース固定用クランプの締結力が不足しているため、ヒータホースの内部を流れる冷却水がホース端部より浸入し、その冷却水によってホースの補強糸が分解されるものがある。そのため、そのままの状態で使用を続けると、ホースの強度が不足し、内部を流れる冷却水の圧力に耐えきれず、ホースが破損して冷却水が漏れ、デフロスタの機能が低下して前面ガラス直前の視野を確保できないおそれがある。
改善措置
全車両、ヒータホース固定用クランプの締結力が不足している箇所のヒータホースと固定用クランプを対策品に交換する。
