Service bulletin 122-K2P3H-06

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

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.
