• Identify System and Add Dye — Determine which system (engine oil, transmission, power steering, fuel) has a suspected leak. Carefully add one 1 oz bottle of A/C Pro UV Dye to the appropriate fluid reservoir or directly into the system, following specific vehicle manual guidelines if available.
• Circulate and Operate Vehicle — Start the vehicle's engine and allow it to run for a sufficient period (typically 10-20 minutes) to circulate the dye throughout the system. For fuel systems, driving the vehicle may be necessary to ensure the dye reaches all potential leak points.
• Inspect with UV Light — Turn off the engine and use a UV flashlight in a dimly lit or dark environment to inspect all relevant components, seals, hoses, and connections. The dye will fluoresce brightly under the UV light, clearly marking the location of any leaks.
