# Service bulletin LI22.20\-P\-080897

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

Complaint Clacking and creaking noises from the engine compartment during load changes, especially when driving off after a cold start and at outside temperatures below 41°F.
