$69.99:Automotive smoke detector wiring harness detector DC 12V EVAP vacuum diagnostic tester（22% off）
Why you need it: Small vacuum leaks and intake issues can create big headaches—rough idle, high idle speed, hard hot starts, acceleration surging, poor fuel economy, and even black smoke from the exhaust. A clogged or leaking vacuum line can also cause drifting idle and stalling, while general air leaks make the engine feel weak and underpowered. That’s why a smoke leak detector is one of the fastest ways to pinpoint hidden leaks without guessing.
Built-in air pump: This AUTOOL smoke machine includes an integrated air pump, so you don’t need to buy extra equipment—saving time and money while keeping the setup simple.
EVAP leak detection (OBD2 vehicles): Most U.S. vehicles made since 1996 include an EVAP service port. Open the port cap, remove the check valve with the spool wrench, install the adapter, and introduce smoke to quickly locate EVAP leaks in the emissions system.
Easy operation: Add 10–20 ml of test oil (commonly Johnson baby oil, not included), connect to the intake, power it from a 12V battery, and watch the system fill with smoke—then follow the smoke to the leak point.
Wide testing range: This automotive smoke tester works on EVAP, intake, cooling/EGR/exhaust, crankcase, engine airtightness, low-pressure turbo leaks, and more—compatible with cars, motorcycles, ATVs, light trucks, and boats.
Smart protection + warranty: Built-in overheat/freeze protection pauses operation to prevent damage, and AUTOOL backs it with a 3-year warranty plus lifelong maintenance support.
