LeakTamer UltraTrace UV Solution Tester Overview

Component Descriptions

<ON> <OFF> Switch turns ON vapor production, for five (5) minutes.
Dipstick used to maintain smoke solution level. Top off regularly to FULL mark by adding solution from dipstick tube.
Power Indicator Lamp turns ON when connecting the power leads to a battery.
Smoke Indicator Lamp turns ON after pressing the <ON> button, indicating the tester is producing vapor.
Hook Insert for hanging LeakTamer. Use hood rod support when hanging on hood.
Supply Hose to introduce vapor into system for leak test.
Flow Control Valve controls vapor flow volume.
Flow Meter establishes a quick PASS / FAIL when determining if the vehicle being tested has a leak.
Cap Plug Kit is used to seal the intake ducting of the engine being tested.
EVAP Service Port Adapter (standard size) connects directly to vehicles with factory service access port for fuel vapor recovery system.
Schrader Valve Removal / Installation Tool removes Schrader valve inside EVAP Service Port. NOTE: Left-handed thread.
Diffuser helps locate wind and water leaks.
Combination White/UV Light locates vapor with white light and fluorescent dye with UV light.
Adaptor Cone is used to introduce vapor into any system that accommodates the cone's size, such as intake/induction and exhaust systems.

Features Included But Not Shown

Vapor-Producing Solution: LeakTamer is shipped with two UltraTraceUV bottles—enough to perform approximately 600 tests.
Water Separator / Filter (inside tester with drain port at bottom of tester) ensures a clean supply of air. It is normal to occasionally see drainage of fluid from this port. Excessive drainage indicates compressor in use requires draining and/or filter system.

Description

One specialized fluid that helps personnel find and fix leaks fast and precisely is the OTC LeakTamer UltraTrace UV Solution 6522-1. When added to the system, the highly fluorescent UV dye in the solution will seep out and shine brilliantly when exposed to UV light. This eliminates the need for significant disassembly or guessing and enables personnel to locate the leak precisely.
The solution works with the majority of the materials used in automotive systems and is safe to use in a variety of automotive systems. Any mechanic or technician who wants to expedite their diagnostic procedure and guarantee precise repairs must have this indispensable instrument.

Initial Setup

Pour entire contents of one (1) 8-oz. UltraTraceUV solution bottle into the vapor chamber.
CAUTION: Use only UltraTraceUV solution in the LeakTamer. Using solutions not recommended by the manufacturer may (1) damage the vehicle being tested, (2) damage the unit, and (3) cause operator injury.
NOTE: Use second bottle of UltraTraceUV solution to regularly maintain at or near the FULL mark on the dipstick.
Install correct air fitting onto the LeakTamer, if not supplied.

Test Setup

Connect the LeakTamer red power cable to a 12V DC power supply. If a battery is used, verify it is in good condition and fully charged.
Connect the LeakTamer black ground cable to the vehicle’s chassis ground.
WARNING: To prevent personal injury, do NOT connect the black cable to a battery ground. A spark in the vicinity of the battery can cause an explosion.
Depending on the tests you are performing, connect an inert gas such as nitrogen or CO2 or shop air supply line to the fitting located on the back of the unit.
When testing EVAP systems: Connect nitrogen or CO2 to the fitting on the back of the unit.
WARNING: To prevent personal injury, do NOT introduce air, which contains oxygen, into the fuel tank. Gasoline fumes inside the fuel tank can cause an explosion. Always connect the LeakTamer to nitrogen or CO2 when testing the vehicle's EVAP system.
When testing systems other than EVAP: Connect air to the fitting on the back of the unit.
Verify shop air or gas pressure is 50 psi to 175 psi/ 3.4 to 12 bar. (100 psi/7 bar is recommended.)

WARNING: Perform all LeakTamer tests with the vehicle engine OFF.

Basic Leak Testing

LeakTamer can be used in virtually any low-pressure vehicle system suspected of having a leak, including EVAP, intake/induction, intercooler and turbocharger, vacuum, exhaust, and wind/water leaks. LeakTamer can also be used to verify air solenoid functions and test components before assembly. These basic steps can apply for testing most systems.

Locate the system port.
Install appropriate port adapter.
Insert vapor supply hose into adapter.
Turn the unit on by pressing the <ON> button.
Close system vent(s).
Continue to fill the system until the flow meter indicates the system is full (ball drops in indicator).
Use the LED lamp to check for leaking vapor or the UV lamp to check for dye deposited at the exact location of the leak.

Flow Meter Measurements

The flow meter measures flow through the system being leak-tested. This is normal while the system is being filled. If flow meter indicates flow after the system is filled, this indicates a leak. The higher the ball is in the flow meter, the larger the leak size. No flow indicates no flow through the system, or no leak.

The position of the ball indicates the size of the leak.

Note: For accurate .010"/.020"/.040" measurements, the flow control valve must be in the fully open position.

Wind and Water Leaks

Set vehicle's climate control to "fresh air" (not recirculate). Set blower on full speed. This creates positive cabin pressure.
Connect supply hose nozzle to diffuser.
Direct vapor path along seals.
Look for vapor disturbance indicating a leak.

Safety Precautions

If the operator cannot read these instructions, operating instructions and safety precautions must be read and discussed in the operator’s native language.
WARNING: To prevent personal injury and / or damage to equipment:

Read, understand, and follow all safety precautions and operating procedures.
Do not use this equipment in a manner not specified by the manufacturer.
Wear eye protection that meets OSHA standards. If using an ultraviolet light to search for leaks, wear yellow UV goggles that meet OSHA standards. Never stare directly into a UV light or shine UV light on skin.
Because of an evaporative system’s volatile fumes, use an inert gas, such as nitrogen, when testing an EVAP system.
Do not perform tests near a source of spark or ignition.
Correctly connect the power supply to the battery and chassis ground.

OTC LeakTamer UltraTrace UV Solution 6522-1 Troubleshooting

Diagnostic Lights

The LeakTamer has two diagnostic lights on the control panel that indicate whether the tester is working correctly. The following table describes the tester’s trouble codes.

Diagnostic Lights		Interval Probable Cause
Green	Red	Interval Probable Cause
√		Constant ON	Sufficient battery power
√		Blinks every one (1) second	Insufficient battery power
√	√	Blink simultaneously every one (1) second	Bad ground or bad power connection at vapor canister
√	√	Blink simultaneously @ four (4)blinks per second	Bad ground at vapor canister or open heating circuit
√	√	Blink alternately @ one (1) blink per second	Bad ground or circuit board failure j
j If circuit boardfailure occurs, firsttry disconnecting powerto the unitfor 10 seconds, then reconnect power. If this failure code occursa second timeduring operation, disconnect the tester andcontact Tech Support.

Problem

Cause

Solution

Green power indicator lamp on

the tester does not come ON.

Poor power supply cable connection.
Battery providing power is too weak.

Secure the connection at positive terminal and chassis ground.
Verify battery is in good condition and fully charged.

Tester is ON, but there is no vapor or air coming out of the hose.

Poor power supply cable connection.
Battery providing power is too weak.
Insufficient supply of shop air,

nitrogen, or CO2.

Too much oil has condensed inside vapor supply hose.

Secure the connection at positive terminal and chassis ground.
Verify battery is in good condition and fully charged.
Verify shop air, nitrogen, or CO2, input pressure is between 50 psi and 175 psi / 3.4 and 12 bar. (100 psi / 7 bar is recommended.)
Drain oil from supply hose.
