Service bulletin TSB100315-051320

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

This Technical Service Bulletin announces the availability of the oil pan full perimeter clamping plates on the following engine platforms: C8.3, C8.3G, C Gas Plus, ISC, QSC8.3, L Gas Plus, ISL, and QSL9. Oil pan full perimeter clamping plates distribute clamping force over the entire oil pan rail which provides greater gasket sealing ability and helps to prevent oil pan gasket leaks. This is a product improvement and is not subject to campaign.
