Add dye to system and let it circulate.

(The dye escapes with refrigerant or host fluid and collects at all leak sites)

Scan system with a leak detection flashlight.

(See all leaks glow brightly)

Click and drag to simulate Tracerline fluorescent dye and leak detection lamp revealing hidden automotive leaks.

It’s a simple fact: circulate refrigerant, oil, coolant, fuel, hydraulic fluid or automatic transmission
fluid and sooner or later leaks will develop.

Leaks are often virtually impossible to find with conventional methods until they result in expensive vehicle failure.

Pinpoint Automotive Leaks

Tracerline fluorescent leak detection changes that. It quickly locates even the smallest and most elusive leaks, including intermittent and multiple leaks that would otherwise be missed. The Tracerline method saves labor, money, and downtime, as well as conserves expensive refrigerant and fluids.

Tracerline leak detection utilizes a simple method that has only two basic parts. A high-intensity Tracerline ultraviolet lamp is teamed up with the appropriate Dye-Lite (for fluid leaks) or Fluoro-Lite (for A/C leaks) fluorescent tracer dye. The fluorescent dye is added to the system and circulated. The system is then inspected with the lamp. Since the dye collects at all leak sites, the lamp will show the precise location of every leak with a bright glow. The dye can remain in the system indefinitely and does not affect system components or performance.
