Product Overview
The AUTOOL SDT102 smoke leak detector is a compact and lightweight automotive smoke tester for quick low-pressure leak detection in EVAP, intake, exhaust, crankcase, engine airtightness, vacuum, and low-pressure turbo systems. With a built-in air pump and pressure gauge, it helps diagnose leaks without an extra air compressor. It works from a DC 12V vehicle battery and is suitable for cars, motorcycles, ATVs, snowmobiles, off-road vehicles, light trucks, and speedboats.

Before You Order And Use
Review the 12V power requirement, testing oil rule, refill method, operating time limit, A/C testing limit, and hot-surface warning before using the SDT102 smoke machine for vacuum leaks.
12V Battery Required
The SDT102 automotive smoke tester must be connected to a DC 12V vehicle battery to operate. Confirm correct polarity before use.
Testing Oil Not Included
Due to logistics restrictions, testing oil is not included. Use liquid paraffin or baby oil purchased locally as the testing fluid.
Add 10-15ml Only
Fill 10-15ml testing oil before use. Do not add more than 15ml at a time, because internal space is needed for smoke generation.
Refill When Smoke Becomes Thin
Only refill when the smoke becomes thin. Always drain the remaining test oil before adding fresh testing oil.
8-Minute Use Limit
Do not operate the smoke leak detector continuously for more than 8 minutes. Allow the unit to rest between uses.
A/C Direct Test Not Supported
SDT102 cannot directly pressure-test automotive A/C systems. It can only assist with segmented A/C pipeline checks under proper conditions.
Safety Reminder
- The intelligent protection system stops operation when the internal temperature exceeds 75°C. Wait for the unit to cool before restarting.
- The metal round section of the smoke tester can become hot during operation. Avoid direct contact to prevent burns.
- Do not refill testing oil while the smoke tester is running.
- If too much oil is added accidentally, drain some oil out before operation; the extra oil can be reused next time.
Key Features
Key Features
SDT102 is designed for fast and simple automotive smoke leak detection with an integrated pump, pressure gauge, EVAP support, broad low-pressure system coverage, and smart protection.
Pressure Gauge Leak Check
Use the pressure gauge to monitor pressure changes and quickly assess whether the tested pipeline may have leakage.
Built-In Air Pump
No external air compressor is required. The built-in pump saves setup time and makes SDT102 easier for DIY and workshop use.
EVAP Detection
Supports EVAP leak detection and is compatible with American cars from 1996+ when used with proper EVAP service access tools.
Wide Low-Pressure Coverage
Supports common low-pressure checks for intake, exhaust, crankcase, engine airtightness, vacuum, pipe fittings, and low-pressure turbo systems.
Smart Protection
Overheat and freeze protection help protect the machine. The unit supports low-temperature work down to -20°C under proper conditions.
Compact Interface
The body integrates the power interface, smoke output, oil filler, pressure gauge, handle, and operation controls in a compact structure.

Applications
Use SDT102 to locate leaks in common automotive low-pressure systems. For high-pressure systems, special test methods or professional tools may be required.
EVAP / Vacuum
Suitable for EVAP and vacuum leak checks when the correct service access tools and adapters are used.
Intake / Exhaust
Helps find leaks in intake and exhaust pipes by filling the test section with smoke for visual inspection.
Crankcase / Oil Seal
Can assist with crankcase, oil seal, intercooler air, and engine airtightness checks under low-pressure conditions.
Fuel / Coolant / Pipes
Supports fuel tank, coolant tank, pipe fittings, and low-pressure turbo system leak checks where smoke testing is appropriate.
How To Use
How To Use
Use liquid paraffin or baby oil, connect the tested pipe, power the unit with a DC 12V battery, and visually locate leaks once smoke fills the pipeline.
Step 1: Add Test Oil
Fill 10-15ml baby oil or liquid paraffin into the detector. Do not overfill. Open the engine cover and hang the detector if needed.
Step 2: Connect The Pipe
Disconnect the pipe that needs testing and connect it to the smoke detector with the proper hose or adapter.
Step 3: Connect 12V Power
Connect the detector to a DC 12V battery, then turn on the power switch so the smoke tester starts working.
Step 4: Locate Leaks
The unit starts producing smoke quickly; the tested pipeline may fill with smoke in about 30 seconds depending on system volume. 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 the testing oil.
- Only refill when smoke becomes thin, and drain remaining test oil before adding fresh oil.
- Do not operate continuously for more than 8 minutes.
- Wait for the detector to cool down if overheat protection is triggered.
- Do not use SDT102 for direct automotive A/C pressure testing.

These answers cover testing oil, oil amount, no-smoke troubleshooting, supported systems, EVAP support, A/C auxiliary testing, power supply, pressure setup, accessories, model differences, and warranty.
Testing oil is not included due to logistics restrictions. If professional test oil is not available, use liquid paraffin or baby oil purchased locally as the testing fluid.
Add 10-15ml before use. Do not add more than 15ml at a time. If too much oil is added accidentally, drain some oil out before operation; the extra oil can be reused next time. Refill only when the smoke becomes thin, and drain remaining test oil before adding fresh oil.
First confirm that the unit is connected to a DC 12V battery with correct polarity. Then check whether 10-15ml liquid paraffin or baby oil has been added, whether the machine has overheated, and whether the smoke has become thin because the oil needs replacement. Do not add oil while the machine is running. If the issue remains, contact support with photos or a short video of the setup.
SDT102 supports low-pressure leak checks for EVAP, intake, exhaust, crankcase, engine airtightness, vacuum, pipe fittings, fuel tank, coolant tank, oil seal, intercooler air, and low-pressure turbo systems under proper test conditions.
Yes. AUTOOL smoke leak detectors can test leaks in the EVAP system. SDT102 supports EVAP leak detection, including American cars from 1996+ when used with the proper EVAP testing tools, service access tools, and adapters for the vehicle.
No. Automotive A/C systems operate at about 1.7-3.0MPa output pressure, while smoke leak detectors generate about 0.1MPa. SDT102 cannot directly pressure-test the automotive A/C system for leaks. It can only assist with segmented A/C pipeline checks under proper conditions.
First pressurize the air-conditioning pipeline using the proper method, then spray smoke near the test section and observe whether airflow blows the smoke. If airflow disturbs the smoke, the location may indicate a leak point for further repair. This is an auxiliary method, not a direct A/C pressure test.
No. SDT102 has a built-in air pump, so no external air compressor is required. It only needs DC 12V vehicle battery power and the correct amount of testing oil.
Most AUTOOL smoke leak detectors use fixed pressure. SDT MASTER allows pressure adjustment. To help protect automotive pipelines, SDT102 should be used according to its preset safe pressure for common maintenance and testing needs.
Different AUTOOL smoke leak detector models include different accessories. For SDT102, confirm the final included accessories by checking the product package information or manual before ordering. Testing oil is not included due to logistics restrictions.
The AUTOOL smoke leak detector series includes SDT101 and SDT103 for EVAP systems around 3.2Kpa, SDT106 and SDT202 for beginners around 12 psi, and SDT203, SDT205, SDT205S, SDT206, and SDTMASTER as standard and high-end models around 15 psi. SDT208 supports up to 35 psi. Different materials, pressure ranges, air source types, modes, accessories, and functions create different price ranges.
AUTOOL provides up to 3 years of warranty support for eligible non-human damage cases. AUTOOL sells smoke leak detectors online and offline in 160+ countries and regions and provides after-sales support for eligible cases.
