Product Overview

The AUTOOL SDT208 smoke leak detector is a professional automotive pipe and vacuum leak tester for repair shops, mobile mechanics, and advanced DIY diagnostics. It combines a built-in air pump, smoke mode, air mode, Standard Mode, and EVAP Mode to help locate low-pressure leaks in EVAP systems, intake lines, exhaust pipes, crankcase systems, fuel tanks, pipe fittings, turbo-related low-pressure areas, and other sealed automotive systems.

Before You Order And Use

Before You Order And Use

Review the SDT208 power requirement, test oil rule, airflow regulator, operating time limit, high-temperature protection, and A/C testing boundary before using the smoke leak detector.

12V / 24V Battery Required

The SDT208 smoke leak detector must be connected to a DC 12V or DC 24V battery power supply before operation.

Testing Oil Not Included

Testing liquid is not included due to logistics restrictions. Use liquid paraffin or baby oil purchased locally as the testing oil.

Add 10-15ml Only

Fill 10-15ml testing oil before use. Do not overfill, and do not add more than 15ml each time.

Open Airflow Regulator

Before use, gently turn the knob to open the airflow regulator valve and prepare the air path for testing.

Refill Only When Smoke Is Thin

Add fresh oil only when the smoke becomes thin. Pour out remaining oil before adding fresh oil and replace detector oil regularly.

8-Minute Use Limit

Do not run the detector continuously for more than 8 minutes. Let the unit rest between test cycles.

75℃ Protection

If the working temperature exceeds 75℃, the intelligent protection system automatically shuts down power. Wait until the unit cools before using it again.

Hot Surface Warning

The round metal section of the detector can become hot during operation. Avoid direct contact to prevent burns.

A/C System Boundary

Do not use the smoke leak detector to directly pressure-test an automotive A/C high-pressure system. Use only for segment-assisted checks under proper conditions.

Safety Reminder

  • Keep the smoke output away from smoke-sensitive parts during leak detection.
  • Do not refill test oil while the detector is running.
  • If the machine enters protection mode, wait for the temperature to drop before restarting.
  • Use the correct adapter and mode for the test area to reduce the risk of pipe damage.
Key Features

Key Features

SDT208 is designed for efficient professional leak detection with fast smoke generation, a built-in air pump, dual pressure modes, pressure and flow monitoring, EVAP protection, and reliable workshop safety functions.

Fast Smoke Output

The smoke generator produces smoke within seconds under proper setup, helping reduce diagnostic time during pipe leak checks.

Built-In Air Pump

No additional air pump is required. The built-in pump saves setup time and makes the detector suitable for shop and mobile automotive repair use.

Air Mode And Smoke Mode

The SDT208 integrates an air pump and smoke generator, allowing users to switch between air testing and smoke leak detection according to the test requirement.

Standard And EVAP Modes

Standard Mode supports up to 35psi, while EVAP Mode is limited below 10psi to better protect vehicle pipes during EVAP testing.

Flow Meter And Pressure Gauge

The air flowmeter, airflow control valve, and pressure gauge help control the test pipeline and identify possible leakage by pressure and flow changes.

Professional EVAP Detection

The EVAP mode meets common repair shop EVAP test needs, supports tiny leak checks down to about 0.5mm, and uses pressure protection to help protect vehicle pipes.

Overheat And Anti-Freeze Protection

The intelligent protection device shuts off power above 75℃ and the unit can work in low-temperature conditions down to -20℃.

Wide Vehicle Coverage

Suitable for many 12V / 24V leak testing scenarios, including cars, motorcycles, snowmobiles, ATVs, off-road vehicles, light trucks, and speed boats.

3-Year Warranty Support

AUTOOL provides 3-year support for eligible non-human damage cases, including product setup, accessory confirmation, and troubleshooting support.

Applications

Applications

Use SDT208 for visual low-pressure leak checks across common automotive sealed systems. Select the proper adapter, pressure mode, and test method for the system being checked.

EVAP System

Use EVAP Mode and suitable EVAP tools to check evaporative emission system leaks.

Intake And Vacuum Lines

Helps locate leaks in intake pipes, throttle-related pipes, vacuum lines, and engine airtightness areas.

Exhaust And Crankcase

Supports visual leak checks for exhaust pipe sections, crankcase systems, and related pipe fittings.

Fuel Tank And Pipe Fittings

Can assist with low-pressure checks around fuel tank sealing areas and automotive pipe connections.

Turbo Low-Pressure Checks

Useful for selected low-pressure turbo, intercooler, and air path leak checks under proper conditions.

12V / 24V Vehicles

Suitable for many cars, motorcycles, snowmobiles, ATVs, off-road vehicles, light trucks, and speed boats.

How To Use

How To Use

Use SDT208 with 10-15ml liquid paraffin or baby oil, a DC 12V / 24V battery, the proper adapter, and the correct pressure mode for the selected test system.

Add Test Oil

Fill 10-15ml baby oil or liquid paraffin into the detector before use. Do not overfill.

Open The Airflow Regulator

Gently turn the knob to open the airflow regulator valve before starting the test.

Connect The Test Pipe

Open the engine cover, hang the detector if needed, disconnect the pipe that needs testing, and connect the proper hose or adapter.

Connect 12V / 24V Power

Connect the detector to a DC 12V or 24V battery, then turn on the power switch.

Select The Mode

Choose Standard Mode, EVAP Mode, Air Mode, or Smoke Mode according to the system being tested.

Locate Leaks

Observe smoke, pressure, and airflow changes. Use a headlamp if needed to check the leak points visually.

Use Notes

  • Testing oil is not included due to logistics restrictions.
  • Use liquid paraffin or baby oil as testing oil.
  • Refill only when smoke becomes thin.
  • Drain remaining test oil before adding fresh oil.
  • Do not operate continuously for more than 8 minutes.
  • If the pressure gauge continues to rise, the tested pipeline may have no obvious leak. If pressure continues to drop, the pipeline may need repair.

    The Autool SDT208 GREAT dual purpose smoke machine for the professional or DIY auto mechanic, as it has some distinct features that can be selected by a simple pressing of the appropriate buttons which sets it apart from many other smoke machines.
    1. It has its own, built in air compressor that makes it very portable so that you do not need to use shop air,
    2. It has a pressure setting that allows a person to perform smoke tests for finding vacuum leaks in vehicle EVAP systems that require low pressure settings in the 1-2 psi range.
    3. It can also be used to perform smoke tests for finding leaks in vacuum or pressure circuits that can be tested at higher pressures in the 25 psi range.
    4. A person can select to pressure test using regular air pressure with no smoke or the smoke feature can be selected to pressure test with smoke.
    i started out with an AUTOOL SDT206 and decided to upgrade to this SDT208 because with the SDT206 i had problems trying to accurately regulate the lower pressures required for smoke testing vehicle EVAP vacuum circuits.

    The SDT208 is a GREAT smoke machine and as of this time I am very happy with its performance.

    The only suggestion i would offer is that AUTOOL provide information on a smoke machine oil that does NOT STINK like i have experienced with using baby oil or mineral oil.

    I really like this unit over my old smoke machine. Major concern is the 12 volt power cord has a 120 Volt type plug receptacle where one may accidently use a 120 volt power cord not remembering this is 12 volt not 120 volt. Could be a serious problem.
