👉 Fault fluid, also known as diagnostic fluid or trouble-finding fluid, is a specialized liquid used in machinery and equipment to facilitate the diagnosis of faults or malfunctions. It contains additives that help in identifying issues by changing color, viscosity, or other properties when certain problems occur. For instance, a fluid might turn from clear to yellow when overheating or darken when there's contamination. These changes allow technicians to pinpoint the exact location and nature of a problem, enabling timely repairs and maintenance. Fault fluid is crucial in industries like manufacturing, automotive, and aerospace, where early detection of faults can prevent costly downtime and ensure safety.
