Remove drainplugs from engine system components and inspect sediment sticking to plug. Grit or

fine metal particles may indicate actual or potential component failure. A few fine particles are

normal. This inspection will help to show defective parts before internal inspection of the

component.

Inspect hose surfaces for broken or frayed fabric. Check for breaks caused by sharp kinks or

contact with other parts of the vehicle. Inspect fitting threads for damage. Replace any defective

part. After assembly and during initial vehicle operation period, check for leaks. Inspect wiring

harnesses for chafed or burned insulation. Inspect terminal connectors for loose connections and

broken parts. Visually inspect castings and weldments for cracks.
