Service bulletin RF-18-03

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

EXHAUST PIPE GASKET OPEN END: There has been some concern with the open end of hoop design being considered a defect in the gasket for P/N AJ17-40-305. The end of this ?hoop? is intentionally modified to press fix the gasket on the exhaust pipe. NOTE: The ?hoop? might become larger during shipping, but you can still use it by pressing this portion down when installing.

MT-002-192019-10-04. Service bulletin. If an engine assembly is replaced after a catastrophic internal mechanical failure, clean the intake manifold internally before installing a replacement engine assembly. If the intake manifold is not cleaned properly, the replacement engine may fail prematurely. Metallic debris from the old engine (with catastrophic internal mechanical failure) may rest inside the intake manifold. When the new engine assembly is installed, debris in the intake manifold will be ingested into the new engine and cause internal damage.
