AUTOOL Smoke Machine Detector 12V
Product description
This smoke leak detector targets common engine breathing and EVAP faults with a practical, all-in-one approach. It helps locate vacuum leaks, intake cracks and EVAP faults quickly, so you spend less time guessing and more time fixing. The tool is useful for home mechanics and pro technicians who need a portable, simple tester that does not demand extra pumps.
Key takeaways

The device brings a direct answer to erratic idle, rough cold starts, increased fuel consumption and visible black smoke, by introducing harmless visible smoke into the faulty circuit. It is especially helpful when symptoms point to vacuum or EVAP failures and you need a visual confirmation, not just error codes. Keep in mind that some models require an EVAP service port adapter and that the kit does not include test oil, so plan ahead. 🔍

How to use it



Fill the detector with the recommended amount of test oil, usually 10ml-20ml of light test oil, then connect the tool to the vehicle intake or EVAP service port. Start the unit from a DC12V supply and watch smoke fill the system while you inspect hoses, seals and connectors. The built-in fan pressurizes the circuit so leaks show as smoke trails. Built-in air pump means no separate pump purchase is needed, saving setup time and extra cost. ⚙️
Where it helps

You can use it on EVAP systems, intake systems, cooling and EGR circuits, crankcase ventilation, exhaust joints and low pressure turbo lines. The visible smoke makes small cracks and loose fittings obvious during a live test, so repairs are targeted and faster. EVAP detection is supported for many North American cars that have service ports, but access locations vary by model so locate the port first. 🚗
Keep in mind that the unit includes protection against extreme conditions. The smoke machine includes overheat and freeze protection that pauses operation if temperatures go out of safe range, and the indicator light will go off during self-protection. Note that test oil is not included and you should not add oil while the unit is operating. AUTOOL Automotive Smoke Machine Lead Detector carries a three year parts warranty and lifetime support according to the seller, with customer service response typically within 24 hours. ⚠️
