【Specialized Smoke Leak Detector】Automotive smoke machine is designed for testing leaks in all DC12V vehicles pipe systems. It can easily check car sealing, throttle shafts, engine block, turbo test system, crankcase system, intake system, exhaust system, fuel tank system, EVAP system, EGR system, cooling system, various pipe fittings leakage problems. 【Built-In Air Pump】 The car smoke detector has a built-in air compressor, which eliminates the need for additional air supply equipment and ensures efficient operation. And the smoke detector is also equipped with a pressure gauge and liquid observation window as well as an overheating protection device, which is safe and humanized. 【Precise Detection】Equipped with an adjustable pressure gauge, this smoke tester accurately detects even the smallest leaks, providing precise diagnosis every time. Includes a 23-piece set of highly effective leak test sealing caps. They feature a special tapered design that provides a tight seal on all openings, ensuring excellent fit. Made of high quality automotive grade plastic for durability and flexibility. 【Easy Operatiopn】 1. Fill the detector with 10ml to 20ml of Johnson's Baby Oil Pink Label (the most suitable oil); 2. Disconnect the car's air intake pipe; connect the car's air intake pipe to the detector; 3. Connect the detector to the DC12V battery and start to work; 4. The pipe will be filled with smoke; check the leakage point. Please note: too much oil will flood the hydraulic cylinder, too little oil will produce less smoke. 【Smart Protection】The smoke tester has overheat and freeze protection it will be in self-protection state after a long working time to avoid the smoke maker overheated, the indicator light will be off. the maximum temperature limit is 75°C, ture on antifreeze protection at a low temperature of -20°C. If it exceeds the working limit, such as over 75 ℃, it will automatically turn off the power to secure the safety of both the operator and device. Do not fill oil while working. 【Wide Range of Applications&Lightweight】The Smoke Leak Detector is used to detect leaks in the ductwork of cars, motorcycles, snowmobiles, ATVs, light trucks and speedboats, and is suitable for all vehicle models. This smoke detector has a lightweight and simple design. The all-in-one design helps service technicians solve leaks quickly and saves repair time.
