1. VISUAL ENGINE/CHASSIS INSPECTION

Purpose:
The purpose of this test is to check the general condition of the engine and chassis.

Visual Engine/chassis Inspection
- Verify there are no fluid or pressure leaks.
- Inspect all wire connections for damage.
- Inspect the manifold absolute pressure (MAP) sensor, intake air temperature 2 (IAT2) sensor, charge air cooler (CAC), and intake for leaks.

Fuel Oil Coolant Electrical Hoses Leaks:

Recommended Procedure:
- Inspect for a leak around the MAP sensor.
- Inspect for a leak around the IAT2 sensor.
- Inspect the fuel system, including the fuel tank, fuel pump, fuel filter housing and fuel lines, for kinks, bends or leakage.
- Inspect for coolant leaks at the radiator and coolant hoses. Check the coolant level.
- Inspect wiring for correct routing, and verify no rubbing or chafing has occurred.
- Inspect all sensors, and verify the connectors are properly secured.
- Inspect the CAC hoses for leaks.

Possible Causes:
- Loose or leaking fuel lines
- Kinked or blocked fuel lines
- Fuel or oil leaks
- Coolant leaks
- Restricted or open CAC hose
- Incorrect connections
