Coolant Reservoir (Driver's Side)
- Verify fluid levels visually through a sight glass or by removing the radiator cap (when cool).
Alternator (Passenger's Side)
- Ensure the alternator is securely mounted with no loose or missing bolts.
- Inspect for frayed or bare wires; secure all wiring.
- Check the alternator belt for ½" to ¾" deflection; it should not be frayed or cracked.
Water Pump (Driver's Side)
- Confirm secure mounting of the water pump and check for leaks.
- Identify whether it is belt or gear driven.
Oil Level
- Locate the dipstick and ensure the oil level is between the add and full marks.
- Explain the procedure of checking oil levels by wiping and rechecking the dipstick.
Steering Box and Hoses
- Ensure the steering box is securely mounted and free from leaks.
- Look for any missing nuts, bolts, or cotter keys and check for power steering fluid leaks.
Power-Steering Reservoir
- Check for secure mounting, no leaks, and that hoses are tightly secured.
- Inspect the fluid level to be between add and full marks.
Power Steering Pump
- Ensure secure mounting and no leaks; identify whether it is belt or gear driven.
Air Compressor
- Check for leaks and ensure the gear is securely mounted.
- Confirm whether it is belt or gear driven with proper belt tension.
Suspension System
- Identify if suspension uses leaf or coil springs and check for cracks, breaks, or misalignment.
Pitman Arm & Draglink
