Final answer:
During a pre-trip inspection, the power steering pump and hose should be checked for proper fluid levels, the color of the fluid, cleanliness of the reservoir, and the presence of air bubbles to ensure the system is functioning correctly.
Step-by-step explanation:
When inspecting the power steering pump and hose during a pre-trip inspection, you should check for:
- Proper fluid levels to ensure the system has enough hydraulic fluid to operate effectively,
- The color of the fluid, which can indicate the condition of the fluid and whether it may need to be changed,
- The cleanliness of the reservoir, since contamination could impair the functioning of the system, and
- The presence of air bubbles, as they can lead to power steering malfunction and indicate a leak or other system issues.
It is crucial to verify these aspects to ensure the smooth functioning of the vehicle's power steering system, which is vital for driver control and safety.
