Product Description
Find leaks in automotive pipes and sealed systems with this FOXWELL SD201 12V smoke leak detector. The unit combines a built-in air pump, smoke generation, flow meter, and pressure output for visual leak testing across EVAP, intake, vacuum, fuel, exhaust, and other vehicle systems.
Product Overview
The SD201 is powered by a 12V vehicle battery. Inject the specified test fluid, connect the supplied smoke hose and adapter to a sealed system, then use air or smoke mode to check for changes in flow and visible smoke escaping from a leak. The source describes a pressure output of 0.8-1.2 bar and short smoke output time.

How the Test Works
- Prepare the system and seal the pipe being tested.
- Add approximately 10-20 ml of test oil as directed by the source, without exceeding the device’s specified fluid amount.
- Connect the hose and the appropriate adapter.
- Connect the unit to a fully charged 12V battery, observing polarity.
- Use air mode and watch the flow meter for changes.
- Switch to smoke mode to help locate the visible escape point.
- Disconnect power and remove the equipment after testing, following the manual.
The source suggests baby oil as smoke fluid. Confirm the approved fluid and procedure in the manufacturer’s instructions before use, and never use fuel, solvent, or another unapproved flammable liquid.
Before You Buy
