| 122-K2P3H-06 | 2017-09-14. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:COOLING SYSTEM. Concerns: Spring band clamp on coolant reservoir Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a possibility that two spring band clamps with too large a diameter were installed on a breather hose for the engine cooling system reservoir. The inadequate pre-tension force of the spring band clamps can result in a small amount of coolant leaking out when the vehicle is driven. |
