Cool Smoke®MP
Multi-Pressure Leak Diagnostics System
Part No. 500-0175
LEAK DETECTION
SERVICE

INTRODUCTION
Congratulations! You are in possession of the most advanced and powerful
(yet simple to operate) multi-pressure diagnostic leak test machine available.
Our patented MotorVac® Cool Smoke® “no heat” technology creates a high
volume, smoke-like vapor eliminating the need for high temperature glow plugs
or resistance coils. The Cool Smoke® MP was specifically developed to OEM
specifications for diagnosing leaks in high pressure air systems such as turbo
chargers and charge air coolers. The Cool Smoke® MP can be used to not only
determine if there is a leak in a system and pinpoint its location, it can also
determine the actual size of the leak allowing the technician to decide whether
a repair is necessary.
The MotorVac® Cool Smoke® MP uses advanced dynamically controlled pneumatics
and microprocessor technology to determine the actual leak size throughout the
entire operational pressure range. The Cool Smoke® fluid will deposit ultraviolet
(UV) dye at the location of small leaks where it would be difficult to see smoke.
The MotorVac® Cool Smoke® MP comes with both a powerful UV light to easily
locate the UV dye deposits at leak points, as well as a powerful white light to
locate the smoke at visible leak points.
The MotorVac® Cool Smoke® Fluid is a unique solution that allows for highly visible
vapor (smoke) to carry UV dye to leak points. The UV dye will be deposited at small
leak locations where the smoke is forced out during a test. Your MotorVac Cool
Smoke MP can perform smoke or leak tests between 3-60 psi (0.2-4.1 bar) while in
MP mode and 0.5 psi (0.03 bar) while in EVAP mode. The MotorVac® Cool Smoke MP
comes prefilled with a charge of Cool Smoke® Fluid and is refillable by the end- user
when the smoke-producing solution is depleted. The smoke it produces, as well
as the UV dye, is non-toxic, solvent free and noncorrosive. The MotorVac® Cool
Smoke® MP needs no assembly and requires no maintenance.
Your MotorVac® Cool Smoke® automatically sets the critical pressure that must
be maintained during EVAP testing. You don’t need to set flow rates and you don’t
need to be concerned with ambient temperatures or barometric pressures. The
MotorVac Cool Smoke® is refillable by the end-user when the smoke-producing fluid
is depleted.
Please review this User Guide to become familiar with the Cool Smoke® MP and
all its features. Thank you for choosing the MotorVac® Cool Smoke® MP.

SAFETY INFORMATION & PRECAUTIONS
To prevent personal injury and / or damage to vehicle or equipment:
• Many automotive manufacturers require the use of nitrogen to be used while
testing the EVAP system. This is because a high heat source or spark could
ignite fuel vapors mixed with air. The Cool Smoke® does not use potentially
hazardous high temperature glow plugs or resistance coils to create smoke.
However, nitrogen should be used to reduce the ignition risk if other potential
ignition sources are nearby. The Cool Smoke can perform its functions using
clean and dry conventional shop air.
• Use this equipment in the manner specified by the manufacturer.
• Understand operating procedures and all safety precautions.
• Correctly connect power supply to battery and chassis ground.
• Use only Cool Smoke® Fluid in the Cool Smoke® MP. Altering the fluid, hoses,
cables, or any other replacement parts will void the warranty; may cause
machine malfunction; may cause damage to the vehicle, to property or may
cause personal injury.
• To view the dye deposit, use the included UV Light and UV enhancing safety
goggles.
• Do not use when vehicle engine is running.
• The 12V DC battery source you use to power the machine must be in good
condition and fully charged.
• Machine input pressure must be 90—150 psi (6.2—10.3 bar). Operate the machine
in an upright position.
TIP: Whenever possible allow the system to vent as far away from where the smoke
is being introduced. This will purge the air and quickly fill the system with smoke.
Once the system is filled with smoke, close the vent, and allow the system to be
pressurized.
TIP: When testing an engine’s intake or exhaust system for leaks, it is recommended
that the engine be cold. Small leaks may be sealed due to thermal expansion
WARNING: Do not overfill unit.
CAUTION: Gloves and safety goggles
must be worn at all times by users and
bystanders when performing this service.

MODES OF OPERATION
FIRST TIME OPERATION
The MotorVac® Cool Smoke® MP has two modes of testing:
Smoke mode: The Cool Smoke® MP will produce high density smoke-like vapor at
set pressures between 3-60 psi, for MP mode, and 0.5 psi, for EVAP mode, to quickly
pinpoint the location of a leak using both visible vapor and UV dye deposits.
Leak mode: The Cool Smoke® MP utilizes two methods to determine if the system
under test is leaking beyond OEM specifications. The machine can use either a
Pressure Decay or Leak Size/ Flow Rate Test that can determine the actual leak size
Smokeless mode: The Cool Smoke MP has this mode, where only air goes into the
system, no smoke and/or UV dye. This mode can be used as a smoke purging / air
only test.
The Cool Smoke® MP comes factory filled with Cool Smoke® Fluid and is ready
to use right out of the box. The air inlet is supplied with a female 1/4” NPT port.
Connect an appropriate coupler that mates with your compressed air supply hose.

EVAP TEST SETUP
CAUTION — Many automakers require the use of a non-combustible gas such as
nitrogen to be used while testing an EVAP system. This is because a heat source or
spark could ignite fuel vapors when mixed with air. The MotorVac Cool Smoke does
not introduce a dangerous heat source. However, other sources of spark or heat
could be present in the surrounding area. The Cool Smoke can perform its functions
using conventional shop air.
Test Setup
ALL tests with the MotorVac® Cool Smoke® MP are performed with the engine off.
1. For OBD-II EVAP systems when the vehicle’s engine is turned off the vent valve
is normally open. Use a scan tool to close the EVAP System to perform any
leak tests.
2. Connect the Cool Smoke® MP’s red (+) battery clip to vehicle’s positive
battery terminal; connect the black (-) battery clip to a solid ground point
as far from the battery as possible.
3. Connect shop air to the MotorVac® Cool Smoke® MP’s inlet located at the back
of the machine. Be sure supply pressure to the machine is between 90—50 psi
(6.2—10.3 bar).
4. Verify the vehicle’s fuel level is below the base of the fuel tank neck.
5. Locate the EVAP service port indicated by its green cap. Remove the Schrader
valve from the EVAP service port using the removal tool (060-0008)
Note: The Schrader valve is a left-hand thread, turn clockwise to remove.
6. Connect the service port adapter (060-0005) to the EVAP service port. Connect
the Cool Smoke’s smoke hose to the service port adapter.
Leak Verification
TIP: A common reason for EVAP codes is a faulty or improperly installed fuel cap.
To rule out this possibility do not disturb the gas cap before performing a leak
verification test. If the vehicle fails the leak size test ensure that the fuel cap is
properly installed and redo the test. If you disturb the fuel cap before doing this test
and the system does not show a leak you will not be able to determine if there is an
intermittent leak or if the fuel cap was the problem.
• Select the LEAK TEST by pressing “select” ( ) button.

EVAP TEST SETUP (CONTINUED)
OTHER LEAK DETECTION APPLICATIONS
Finding the Leak
TIP: It is best to perform all testing in calm air, so that the smoke exiting the leak
will not be blown away impairing your view of the leak.
1. Ensure all steps outlined in test setup were followed. For best performance
fully unwind the outlet hose.
2. Remove the fuel cap to allow the air out and the unit to fully fill the system with smoke.
3. Select the SMOKE TEST by pressing “select” ( ) button to begin
creating smoke. The tester has a built in 5-minute timer and will stop making
smoke when the timer expires. To stop making smoke earlier press
the “exit” ( ) button.
4. After a solid stream of smoke is observed exiting the fuel fill neck, reinstall the fuel cap.
5. Using the supplied light search the EVAP system for smoke exiting a leak.
6. UV light can be used to pinpoint leak locations. This is useful for hard to see
locations such as the top of the fuel tank or behind panels.
7. TIP: The longer smoke is allowed to exit a leak more UV dye is deposited
at the leak location.
8. Repair the leaks and perform the leak test again to verify repair and
that there are not more leaks present in the system.
Exhaust Leaks
Escaping exhaust gases can be very dangerous to the occupants of a vehicle yet
these repairs are neglected — but so easy to find with the MotorVac Cool Smoke.
1. Put the vehicle on a lift to expose the underside. With the engine turned off,
simply insert the exhaust adapter cone into the tail pipe of the vehicle being
tested. Insert the smoke supply line nozzle into the exhaust cone’s hose
opening. On dual exhaust systems ensure that each tail pipe is plugged.
2. Look for the smoke exiting wherever there is a leak.
3. Even though exhaust leaks are very easy to find with MotorVac Cool Smoke, here
are three helpful tips to make finding exhaust leaks even easier:
• It is best to test a cold exhaust system rather than a hot one because
the catalytic converter may consume some of the smoke, but more
importantly, many small exhaust leaks are only visible on a cold exhaust
system due to ‘thermal expansion’.
• Seal off the vehicle’s intake system to achieve proper system pressure in
the event both an intake and exhaust valve are open in the same cylinder
at the same time.
