Identify Potential Leaks With Visible Smoke
Investigating a suspected air leak can be difficult when the problem is not immediately visible.
The AUTOOL SDT100 Automotive Smoke Leak Detector introduces visible smoke into suitable vehicle systems, helping reveal potential leak locations where smoke escapes.
With a built-in air pump, compact body, and included testing accessories, the SDT100 provides a practical tool for automotive troubleshooting and maintenance.
Designed for workshop and experienced DIY use, it brings smoke generation and airflow into one portable diagnostic unit.
Check Your Testing Setup Before Use
The SDT100 is intended for smoke-based leak investigation in compatible automotive systems. The correct connection method and testing procedure depend on the vehicle and system being inspected.
The unit requires an external 12V DC power source and suitable test oil. It includes a smoke hose and several connection accessories, but these do not guarantee a direct fit for every vehicle or testing point.
Works With:
- Suitable automotive systems that support the specified smoke-testing method.
- Appropriate connection points using the included or separately obtained adapters.
- A compatible external 12V DC power source.
Does Not Work As:
- A standalone OBD-II code reader or electronic fault scanner.
- A self-powered battery-operated tester.
- A guaranteed direct-fit tester for every vehicle, fitting, or sealed system.
Before testing, confirm the vehicle manufacturer's procedure, pressure requirements, and correct connection point. Do not assume that every system shown in supplier advertising is suitable for the same test procedure.
Integrated Air Pump For A More Convenient Setup
The SDT100 features a built-in air pump, removing the need for a separate external air compressor during its intended operation.
The unit connects to an appropriate external 12V DC power source using the supplied battery clamp cable.
Its portable enclosure, integrated carrying handle, and dedicated smoke output connection make it practical to position near a vehicle during supported testing procedures.
Visible Smoke For Focused Leak Investigation
The SDT100 uses a low-oxygen combustion operating principle to produce visible test smoke.
When introduced into a suitable system under the correct testing conditions, escaping smoke can help indicate possible leakage points.
This makes the device useful for investigating suspected leaks in compatible automotive assemblies, including applications described by the manufacturer for intake and EVAP-related testing.
Smoke testing is a diagnostic aid. Results depend on correct setup, system conditions, and the nature of the leak. Further inspection or testing may be necessary to establish the cause of a vehicle fault.
Compact Construction With Essential Testing Accessories
With a main housing measuring approximately 7.09 × 4.02 × 5.63 inches, the SDT100 is compact enough for convenient positioning in a garage or workshop.
The unit features a carrying handle, front-mounted controls, visible indicator lights, and ventilation openings.
Its supplied accessory kit includes a smoke hose, connector fittings, a tapered cone adapter, an inflatable sealing accessory, and supporting tools for appropriate testing setups.
The included refill bottle is supplied empty. Test oil must be obtained separately.
Understand The Setup Before Testing
The product operating instructions describe an initial fill of 10 mL of baby oil, connection to an external 12V DC battery, and approximately 30 seconds before the connected pipe begins filling with smoke.
The correct vehicle-side connection and test procedure must be established before operation. Appropriate precautions are especially important around fuel-related systems, hot components, and vehicle electrical connections.
Follow the manufacturer's operating instructions, confirm system pressure limits, and use the device only in suitable conditions. If the correct testing procedure is uncertain, qualified automotive assistance is recommended.
The device does not replace proper system diagnosis or repair.
Designed For Practical Workshop Use
The SDT100 combines smoke generation, a built-in air pump, and a compact carrying design for automotive diagnostic workflows.
Its straightforward layout supports use in suitable workshop environments where technicians and experienced vehicle owners need to inspect suspected leakage points.
For buyers seeking a dedicated smoke-testing device rather than a general-purpose scanner, the SDT100 offers a focused approach to visual leak investigation.
