Study Notes

Brake System

Brake Fluid Vacuum Hose: Ensure no looseness, cracks, or leaks are present.
Brakes: Check for pad wear, leaks of brake fluid at wheel brakes, and inspect hoses for cracks or worn conditions.

Tires

Tires: Inspect wear bars using a penny; should read 4/32" depth in front and 2/32" in rear. Ensure no mismatched, cut, or damaged tires; front tires cannot be retreaded.
Tire Gauge Reading: Confirm tire pressure is set to 55 PSI as noted inside the door.

Fluid Levels

Coolant: Check level of the tank and inspect hoses for cracks and leaks.
Power Steering Fluid: Verify the dipstick location and ensure fluid level is above the refill mark.
Transmission Fluid: Check while the engine is running to ensure adequate levels for effective gear shifting.

Engine Components

Engine Computer: Inspect the connection of the large wire located on the right side of the engine.
Engine Oil: Assess the oil level during the engine compartment inspection.

Belts and Hoses

Engine Belt: Look for wear or fraying; should be tight. Replace serpentine belts every 60-70,000 miles.
Electrical Wires: Check right side for any frayed wires or cuts.

Suspension and Steering

Shocks: Verify that springs are intact, bolts are tight, and there are no oil leaks on shock absorbers.
Front and Rear Suspension: Inspect for cracks or breaks in leaf springs; ensure rubber bushings are tight.
Steering System: Steering wheel play should not exceed 10 degrees (about 2 inches) for responsiveness.

Miscellaneous Checks

Cab Inspection (Vehicle On): Test controls (steering, brakes, horn), inspect mirrors/windshield, ensure emergency equipment is present.
Passenger Areas: Check emergency exits, secure seats, and functionality of seatbelts.
Cargo: Ensure all cargo is secured and properly balanced.

Other Components

Fire Extinguisher: Must be tested every few months for readiness.
Exhaust System: Inspect for leaks that could allow carbon monoxide to enter cabin; ensure components aren't loose or rubbing against other systems.
Wheels and Rims: Inspect for damage, rust around nuts, loose nuts, and ensure no welded wheels/rims are present.

Safety Checks

Hydraulic Brake Check: Pump brake pedals three times, then hold for five seconds; pedal should not move if in good condition.
Emergency Brake Check: Set parking brake, shift vehicle to low gear, and gently release the clutch to test engagement.

Visibility and Lighting

Front Inspection: Check lights, reflectors, wipers, windshield, secure hood, and license plate.
Rear Inspection: Ensure lights and reflectors, license plate visibility, splash guards, and bumper condition are satisfactory.

Dashboard Inspection

Cab Dash: Ensure warning lights turn off, check for no check engine lights, and ensure vital gauges (temperature, voltage, tachometer, fuel) are functioning properly.
