Product Overview

The AUTOOL SDT205 is a 12V automotive smoke leak detector with a built-in air pump, independent Air Mode and Smoke Mode, and a visual pressure gauge for low-pressure pipe leak checks. It helps locate leaks in intake, exhaust, vehicle sealing, fuel tank, pipe fittings, EVAP, vacuum, and other suitable low-pressure automotive systems.

Before You Order And Use

Before You Order And Use

Review the 12V power requirement, test oil rule, operating time limit, overheat protection, and A/C system limitation before using the SDT205 smoke leak detector.

12V Battery Required

SDT205 must be connected to a DC 12V battery for operation. It is intended for 12V DC automotive testing environments.

Testing Oil Not Included

Due to logistics restrictions, testing oil is not included. Use liquid paraffin or baby oil as the testing liquid.

Add 10-15ml Only

Fill 10-15ml testing oil before use. Do not exceed this range, because overfilling leaves less space for smoke generation.

Refill When Smoke Gets Thin

Add fresh oil only when the smoke becomes thin. Do not add more than 15ml each time, and drain remaining old oil before refilling.

8-Minute Use Limit

Do not run the smoke leak detector continuously for more than 8 minutes. Allow interval rest between tests.

75°C Protection

The intelligent protection system automatically shuts off power if the unit exceeds 75°C. Let it cool before restarting.

Safety And Test Boundary Reminder

  • The round metal section can become hot during operation. Avoid direct contact to prevent burns.
  • Do not refill test oil while the smoke detector is running.
  • Keep smoke away from smoke-sensitive parts during leak detection.
  • SDT205 cannot directly pressure-test an automotive A/C high-pressure system. It may only be used for segment-assisted pipeline checks under proper conditions.
Key Features

Key Features

SDT205 combines a built-in pump, smoke generation, pressure observation, dual mode control, compact workshop design, and broad low-pressure leak detection coverage.

Built-In Air Pump

No external air compressor is required. The integrated air pump saves setup time and is convenient for mobile automotive repair.

Air Mode And Smoke Mode

Independent Air Mode and Smoke Mode switches let you use the built-in air pump and smoke generator according to the test need.

Visual Pressure Gauge

The external gauge helps observe pressure behavior. A pressure drop may indicate a pipeline leak that needs further inspection and repair.

Fast Smoke Output

The machine begins producing smoke quickly, and the test pipe can be filled with smoke in about 30 seconds for visual leak location.

Wide Low-Pressure Leak Checks

Suitable for intake, exhaust, vehicle sealing, fuel tank, pipe fittings, EVAP, vacuum, and other proper low-pressure test points.

Portable Workshop Design

A compact body, handle, cone adapter, airbag adapter support, and 3-year warranty support make it practical for workshops and repair users.

How To Use

How To Use

Use SDT205 with a DC 12V battery and 10-15ml liquid paraffin or baby oil. The pipe can be filled with smoke in about 30 seconds, allowing visual leak detection.

Add Test Oil

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

Connect The Test Pipe

Open the engine cover, hang the detector if needed, then disconnect the pipe that needs testing and connect it to the detector.

Connect 12V Power

Connect the detector to a DC 12V battery, turn on the power switch, then use Air Mode or Smoke Mode according to the test need.

Locate Leaks

In about 30 seconds, the pipe will be filled with smoke. Check leak points visually and use a headlamp if necessary.

Use Notes

  • Testing oil is not included due to logistics restrictions.
  • Use liquid paraffin or baby oil as testing oil.
  • Only refill when smoke becomes thin.
  • Drain remaining test oil before adding fresh test oil.
  • Do not operate continuously for more than 8 minutes.
  • Wait for the detector to cool down if overheat protection is triggered.

    So far, I haven’t had a chance to use it. But we do have it just in case. When we do get an opportunity to use it and make sure the product is functioning as it should, we will write another review. So far, everything looks good.
