Initial Inspection and Diagnostic Overview

A visual inspection consists by physically looking for the possible cause of a malfunction. A careful and thorough visual inspection of components may quickly identify the cause of a malfunction and eliminate the need for diagnostic testing.

To perform a visual inspection of the engine, look for such things as disconnected connectors or hoses, misrouted hoses, leaky fluids, corroded battery terminals, or bare wires. If a malfunction is not resolved by the visual inspection, proceed with diagnostic testing according to the instructions.
