Because of the inter changeability and similarity of
many engines, engine sub-assemblies and parts regard­
less of which passenger vehicle they are used in, typical
illustrations and procedures are used (except where
specific illustrations or procedures are necessary to
clarify the operation).
bench operations are used, most single operations, when
not part of a general overhaul, should be performed (if
practical) with the engine in the vehicle.

• Remove engine splash shields.
• Disconnect neutral safety switch wire at connector
