Service bulletin GCUS-3-844

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

17069 - Service Update. The counter bore in the torque converter housing used for auxiliary coolant pump attachment was drilled deeper than specification. The increased counter bore depth limits the usable thread distance for the original fastener to contact. There is only one fastener used to hold the pump. Replace the double ended auxiliary coolant pump mounting stud with revised attachment bolt.
