INSTRUCTION MANUAL
Leakfinder®
Model No. WV604
Diagnostic Smoke® Vapor Machine
with UltraTraceUV®Dye Solution
Leak Detection System for the Professional Technician

Caution and Usage Tips

ALWAYS use Tester with vehicle engine turned <OFF>.
Use this equipment in the manner specified by the manufacturer.
Follow common sense safety precautions.
Connect Tester’s black cable to chassis ground.
Use UltraTraceUV® Smoke Solution No. P0712UV in Tester. Using a non-approved
solution can cause damage to vehicles being tested and may cause personal injury.
Do not leave Tester’s hose or power cables connected to the vehicle if tests are not
being performed.
Do not perform test near source of spark or ignition.
Wear appropriate eye protection.
Wear yellow glasses supplied when using ultraviolet light.
Air or gas pressure supplied to Tester can be 50 to 150 PSI (3.4 to 10.3 bar).
Connect Tester to compressed air for general purpose leak detection applications.
Connect Tester to inert gas, such as nitrogen, when testing fuel vapor (EVAP) system.
Note: DO NOT use workshop air for EVAP testing. Adding oxygen to the fuel vapor
space can create a flammable mixture in the fuel tank.
When using alternate source of UV light, use light that includes 405 nanometer (nm)
UV light range.
The more time smoke is allowed to exit a leak, the more dye will be deposited at that
leak location.
When operating the Tester in near freezing temperatures, cycle the operation of the
Tester 15 seconds <ON> and 15 seconds <OFF> for approximately the first minute or
two of operation. This will allow the Tester to reach optimum operating
temperature.
When testing an engine's intake or exhaust system for leaks, it is best if the engine is
cold. Small leaks may be sealed due to thermal expansion.
When testing a closed system, such as the EVAP system, it is best to purge the ‘non-
smoke’ air out of the system by leaving an opening in the system being filled. Close
the system once smoke exits and continue to fill with smoke. This quickly fills the
system with smoke.

Accessories Included
UltraTraceUV®: (P0712UV) this patented solution is the only Automaker-approved
smoke-producing solution in the world. The solution’s chemistry is specially formulated to
withstand vaporization temperatures, is designed not to damage vehicle components and
contains a special dye that deposits at the exact location of a leak. Will not harm
automotive systems and each bottle will perform approximately 300 tests. (12 oz. / 355
ml). (Part No. is for one bottle, two bottles included with Tester).
Combination Light: (WVA-065) white light, for easier smoke location and ultraviolet (UV)
light, to highlight the fluorescent dye deposited at the exact location of a leak. Also has
laser pointer.
Standard Size Service Port Adapter: (WVA-06) connects to factory service port on many
OBD-II vehicles.
Schrader Removal / Installation Tool: (WVA-049) fits both sizes of Schrader valves in
vehicles with factory OBD-II service port fittings.
Cap Plugs Kit: (WVA-02) used for sealing some systems during leak testing.
Smoke Diffuser: (WVA-03) locates leaks around doors, windows, sunroofs and trunk
compartment seals.
Adapter Cone (standard): (WVA-01) for introducing smoke into the exhaust system or the
induction system. Cone is 1” x 3.5” and 6” long (25.4 mm x 89 mm x 152 mm).
Adapter Cone (large): (WVA-067) Cone is 3.5” x 6” and 4.5” long (89 mm x 152 mm x 144
mm).
Air fitting: Two are supplied. The automotive style fitting is already installed on the tester.
The spare fitting is an industrial fitting but also a popular one in auto facilities.

Or
1.
Or
1.
Connect to workshop air for general
purpose leak testing.
Connect to Nitrogen, or other inert gas, when
testing fuel evaporative (EVAP) system.
Regulate nitrogen from 50 to 150
PSI (3.4 bar ~ 10.3 bar)
Inert Gas Pack
Optional accessory; Inert Gas Pack Kit (WVA-060).
When filled with liquid CO2will perform
approximately 50 EVAP tests.

> Connect red clip to 12V-DC power.
> Connect black clip to chassis ground.
> Use cone to access intake
system and connect smoke supply hose to cone.

> Use white light to find the smoke
.
> Use UV light
and yellow glasses
to find the dye
.
> Press START button.
> Green and red lights are <ON>.
>5-minute timer.

Other Leak Samples
Your Leakfnder® can be used in virtually any vehicle low pressure system suspected of having a leak, such
as; intake / induction, intercooler and turbocharger, vacuum, exhaust, EVAP and even wind/water leaks.
Can also be used to verify air solenoid functions and test components prior to assembly.
Exhaust
Fluorescent Dye Deposit
The UltraTraceUV® smoke solution contains a special
ultraviolet-activated fluorescent dye that deposits at
the exact location of a leak. Use the UV light provided
to highlight the dye.
>The longer the smoke is allowed to exit a leak, the
more dye will be deposited.
>This technology has been designed so that the dye
deposits only if there is pressure-differential. So for
instance; the dye will deposit when exiting a leak but
will not deposit during a wind and water leak test.

Technical Specifications
NOTE: A common question asked is if one can use a very basic generic mineral oil, such as ‘baby oil’, in
the Leakfinder®to create the smoke vapor.
Your Leakfinder®will create smoke vapor with baby oil, but we do not recommend it. The patented
UltraTraceUV® smoke solution supplied with your Leakfinder®; will perform hundreds of tests (is very
economical to use); is the only solution in the world approved by the OEMs; and will not void any vehicle
factory warranties. Plus you have the added benefit of the trace dye that marks the exact location of a
leak, increasing diagnostic accuracy. UltraTraceUV® solution is not a “generic” mineral oil. In fact, generic
mineral oils are not intended for this type industrial use. The generic mineral oils break down, evidenced
by its foul odor and they could damage vehicle components and void factory warranty.
