Product description

【SMOKE MACHINE LEAK TESTER】DLNLIY-T90 smoke machine is a professional detector for automotive pipe system leaks. It can accurately pinpoint over 99% of pipe leakage points within minutes. This leak detector can do smoke testing of multiple systems, such as EVAP systems, Intake Systems, Cooling/EGR/Exhaust Systems, Crankcase Systems, Engine Airtightness, Vacuum Leaks, Low Pressure Turbo leaks.Applicable cars, motorcycles, snowmobiles, off-road vehicles, ATVs, light trucks and speedboats boats
【Super Helper】 This EVAP smoke machine leak tester can precisely locate over 99% of pipe leaks in just a few minutes. Such as these issues, 1. A vacuum hose rupture will make the mixture too rich, increase idle speed, cause starting issues in a warm car, lead to engine surging during acceleration, significantly raise fuel consumption, and produce black smoke from the exhaust pipe. 2. Air leakage in the vacuum tube can make the engine run poorly. 3. Blocking can cause the idle speed to fluctuate, making it prone to stalling
【Easy Operation】1. Fill the detector with about 15-20ml of baby oil or paraffin oil. 2. Disconnect the car’s intake pipe and connect it to the detector. 3. Connect the detector to the DC 12V battery to start it. 4. The pipe will fill with smoke within 10 seconds, generating enough output to detect even tiny leaks, ensuring quick and precise problem identification (NOTE: This product includes an oil bottle, not test oil)
【AIR MODE & SMOKE MODE】The EVAP Smoke Machine Leak Tester adopts Air Mode and Smoke Mode. In Air Mode, leaks can be tested by injecting air into the pipe (no test oil required). In Smoke Mode, hidden problems can be revealed with visible smoke, helping you accurately identify leak points(must be used with testing oil or mineral oil/baby oil)
【Smart Protection】This automotive smoke tester features overheat and freeze protection. It automatically shuts off if the temperature exceeds 167°F (75°C) and provides freeze protection down to -4°F (-20°C), ensuring the safety of both the operator and the testing equipment
Customers find the smoke machine works well, with one mentioning it successfully located an air leak on their Wrangler. They also praise its quality, with one describing it as a great little smoke generator.
