Introduction Congratulations! You are in possession of the most useful, yet simple to operate Evaporative Emissions (EVAP) System diagnostic tester available today. This patented Cool Smoke technology creates diagnostic vapour without the need for high temperature glow plugs or resistance coils. When testing an EVAP system an inert gas such as nitrogen should be used to reduce the risk associated with introducing air into a gas tank.

Dual Mode Operation The MotorVac Cool Smoke leak tester utilizes two separate modes for testing: LEAK TEST MODE: Allows you to quickly determine if a leak exists without smoke. SMOKE MODE: Quickly finds the leak utilizing both visual-vapour (smoke) and UV dye deposits. The Cool Smoke fluid is a unique solution that allows for highly visible vapour (smoke) to carry UV dye to leak points. The UV dye will be deposited at small leak locations where the smoke is forced out a leak.
Getting to Know the Cool Smoke 1 4 10 5 11 2 3 6 * Leak size in 7 thousandths of an inch 8 9 Component description: 1. SMOKE SOLUTION DIPSTICK: Measure fluid level with dipstick fully installed. Keep fluid level in hatched area on the dipstick. The unit is filled through the dipstick tube. CAUTION: DO NOT OVERFILL THE UNIT. 2. SMOKE BUTTON: Press to activate smoke creating mode, press again to cancel smoke creating mode. Note: The unit will automatically stop creating smoke after 5 minutes. 3.
Cautions and Usage Tips 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 vapours 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.
Initial Setup The Cool Smoke comes supplied with a 200ml (6.8 oz.) bottle of Cool Smoke FLUID. (PN: 400-1054) 1. The unit needs to be filled with fluid before being used for the first time. 2. Remove the dipstick. 3. Install the bottle fill nozzle and pour fluid into the machine through the dipstick tube. 4. Connect appropriate air/gas fitting on the bulkhead at the back of the unit. Your Cool Smoke is now ready for its first use! 4 info@motorvac.com www.motorvac.
Included Accessories 060-0005 – SERVICE PORT ADAPTER (standard size) connects to factory service port on most OBD-II vehicles. 060-0008 – SCHRADER REMOVAL / INSTALLATION TOOL fits both sizes of Schrader valves in vehicles with factory OBD-II service port fittings.
EVAP System Overview The vehicle’s Fuel Vapor Recovery System is the most neglected part of the vehicle’s emission system, according to the Environmental Protection Agency (EPA). The vehicle’s EVAP system is used to collect fuel vapors from the fuel tank. These vapors are stored in a canister filled with activated charcoal. The EVAP system allows the fuel vapors to be drawn from the canister and combust during certain operating conditions.
STEP 1 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. 1.
Other Leak Detection Applications • Vacuum and induction leaks • Exhaust leaks • EGR valve leaks • Oil seals and gasket leaks • Idle motors and solenoid leaks • Brake booster leaks • Component testing (radiators, water pumps and valves) • Under dash leaks • Intercooler and turbo charger leaks • Wind and water leaks (windows & sunroofs) Vacuum and Induction Leaks 1. Select the correct size cap plug (supplied) to seal the system, but do not seal the system yet.
Other Leak Detection Applications (Cont.) 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.
Other Leak Detection Applications (Cont.) Oil Seals and Gasket Leaks Many oil leaks can be located with the MotorVac Cool Smoke. It is important to understand that the MotorVac Cool Smoke will only find leaks that will allow air to flow through them. Example: A cam seal may allow air to pass through whereas a drain plug or pressure sensor will not. To locate oil leaks it is necessary to pressurize the crankcase with smoke. 1.
Other Leak Detection Applications (Cont.) Under Dash Leaks Under dashboard leaks can be very difficult to locate. The MotorVac Cool Smoke can confirm or eliminate the possibility of an under dash leak in minutes. Most vehicles have a common vacuum supply line that originates at the engine intake. This vacuum source comes through the firewall to supply the climate control functions as well as other systems in the vehicle.
Other Leak Detection Applications (Cont.) Wind and Water Leaks from sunroofs, windows and windshields One of the toughest leaks to find on an automobile is wind / water leaks around the doors, windows, and sunroofs. It isn’t safe or practical to search for these leaks while driving at highway speeds although that is when they are most noticeable.
Trouble Shooting Chart Symptom Possible Cause Solution Gurgling sound while making smoke or fluctuation on the flow gauge while in leak detection mode. 1. The tank may be overfilled. Pull the outlet hose off the unit and make smoke again. If the gurgling sound is gone fluid has condensed in the outlet hose. Let the hose hang down vertically so any fluid drains out of the line. The ball on the flow gauge hangs up or sticks Dirt or moisture from contaminated supply air has entered the gauge. 2.
