Service bulletin PIB 538

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

Newmar has made a change to the water pump circuit fuse on certain coaches to improve customer experience. In most cases, the 10 amp fuse installed by the factory is sufficient. However, some coaches equipped with a ShurFlo water pump (Newmar part # 127488) blow the 10 amp water pump fuse.
