# Service bulletin SB25\-J\-001

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

SERVICE BULLETIN: SOME CUSTOMERS MAY COMPLAIN ABOUT A WHISTLING NOISE FROM THE ENGINE, LACK OF POWER, OR A VISIBLE ALARM FROM THE CHECK ENGINE MALFUNCTION INDICATOR LIGHT \(MIL\). DEALERS MAY FIND THAT THIS ISSUE IS CAUSED BY A HOLE IN THE CHARGE AIR COOLER \(CAC\) HOSE NEAR THE COMPRESSOR INLET HOSE. WHENEVER THE CAC HOSE IS REPLACED, ISUZU RECOMMENDS DEALERS ALSO INSTALL A NEW HOSE CLIP TO PREVENT THE COMPRESSOR HOSE FROM DAMAGING THE NEW CAC HOSE IN THE FUTURE.
