Checking fluid levels is critical for preventing vehicle breakdown and ensuring the proper operation of various systems within the vehicle. Fluids such as engine oil, coolant, brake fluid, transmission fluid, and power steering fluid play vital roles in the functioning of a vehicle. For instance, engine oil lubricates moving parts, preventing wear and tear, while coolant helps maintain an optimal engine temperature and prevents overheating. Insufficient levels of these fluids can lead to mechanical failures, reduced performance, and potentially dangerous driving situations.

Regular checks can also identify leaks or other issues before they escalate, allowing for timely maintenance and repairs. Maintaining appropriate fluid levels ensures that all systems operate smoothly, contributing to the overall safety and reliability of the vehicle while reducing the risk of roadside breakdowns.
