Do not use an unsupported power source.Add 10-15ml Test OilFor a safer filling rule, add 10-15ml liquid paraffin or baby oil before use. Do not overfill the unit.Testing Oil Not IncludedDue to logistics restrictions, testing oil is not included. Buy liquid paraffin or baby oil locally.Open The Airflow RegulatorBefore use, gently turn the knob to open the airflow regulator valve so smoke and airflow can pass properly.Refill Only When Smoke Is ThinAdd fresh oil only when smoke becomes thin. Drain remaining old oil before adding fresh oil.Avoid OverfillingIf too much oil is added accidentally, drain some oil out before operation. Do not fill more than 15ml at one time.Do Not Run Over 8 MinutesDo not operate the car smoke leak detector continuously for more than 8 minutes. Allow interval rest between tests.75°C ProtectionThe intelligent protection device shuts off power when the internal temperature exceeds the working limit, such as over 75°C.Hot Surface WarningThe round metal part can become hot during operation. Avoid touching it directly to prevent burns.Safety And Compatibility RemindersKeep the smoke away from smoke-sensitive parts such as headlights during leak detection.Do not refill oil while the detector is running.Do not put the product into water or other liquid, and do not use sticky liquid as test oil.Turn off the vehicle ignition and keep the engine off when performing vehicle leak tests.The SDT203 cannot directly pressure-test automotive A/C systems because A/C system pressure is much higher than smoke detector output pressure. Use it only for segment-assisted A/C pipeline checks under proper conditions.Key FeaturesKey FeaturesSDT203 is designed for efficient low-pressure leak detection with fast smoke generation, an integrated pump, visual pressure and flow monitoring, portable handling, and built-in safety protection.Fast Smoke OutputThe SDT203 generates a large amount of smoke quickly after the smoke switch is pressed, helping shorten the time needed to locate visible leak points.Built-In Air PumpNo additional air pump is required. The built-in pump saves setup time and helps reduce extra tool cost.External Pressure GaugeThe pressure gauge helps judge pipeline sealing. Stable or rising pressure usually indicates better sealing, while falling pressure may indicate a leak.Flow Meter WindowThe visible flow meter helps observe airflow changes during testing and supports safer, more controlled leak diagnosis.Flow Adjustment KnobDifferent vehicle pipes may require different airflow. The adjustment knob helps control flow to protect the test system.Compact Hook DesignThe compact body and hook make it easy to carry, store, and hang under the hood while testing.Wide Vehicle CoverageSuitable for many DC 12V vehicle leak checks, including cars, motorcycles, snowmobiles, ATVs, off-road vehicles, light trucks, and speedboats.Overheat And Low-Temperature ProtectionThe intelligent protection device shuts down the unit when temperature exceeds the safe working limit and supports operation in low-temperature environments.3-Year SupportAUTOOL provides up to 3 years of warranty support for eligible non-human damage cases, with help for setup, accessories, and troubleshooting.

Direct high-pressure A/C system leak testing is not supported.Vehicle TypesSuitable for many cars, motorcycles, snowmobiles, ATVs, off-road vehicles, beach cars, light trucks, and speedboats.Engine And Intake AreasHelps check intake systems, exhaust systems, engine airtightness, and pipe fittings for visible smoke leaks.EVAP And Fuel Tank SystemsCan be used for EVAP and fuel tank leak checks with proper adapters and vehicle test access.Car Sealing TestsUseful for locating suspected sealing leaks where smoke can reveal gaps, cracks, or loose fittings.Various Pipe FittingsSupports low-pressure pipeline checks where the test connection can be sealed safely.A/C Auxiliary Checks OnlyDo not use SDT203 to directly pressure-test an automotive A/C system. It may only assist segmental pipeline observation after proper pressurization by suitable methods.How To UseHow To UseUse the SDT203 with a DC 12V vehicle battery and 10-15ml liquid paraffin or baby oil. Allow enough time for the target pipe or system to fill with smoke before checking leak points.Add Test OilFill 10-15ml baby oil or liquid paraffin into the oil refill port before use. If too much oil is added, drain some oil out before operation.Install The Hook And Open AirflowInstall the hook onto the hook port and hang the detector under the hood if needed. Gently open the smoke flow control valve.Connect The Smoke HoseTurn off the vehicle ignition, disconnect the pipe or test access point, and connect the smoke hose to the smoke outlet and target pipe.Connect DC 12V PowerConnect the red clamp to positive ( ) and the black clamp to negative (-). A fully charged 12V vehicle battery is recommended for consistent performance.Generate Smoke And Locate LeaksPress the smoke mode switch. The unit generates smoke quickly; depending on system volume, allow about 30 seconds or longer for the pipe to fill, then use a light to check suspected leak points.Use NotesThe comparison chart marks smoke production in about 5 seconds, while the tested pipe may take longer to fill depending on system size and sealing.The smoke mode may stop automatically after a working cycle. To stop manually, press the smoke mode switch again.Leave the unit to blow residual smoke out of the nozzle after stopping smoke mode.Do not exceed the continuous operation limit. Allow the machine to rest between tests.If overheat protection is triggered, wait until the detector cools before restarting.

What Testing Oil Should I Use For SDT203? Use liquid paraffin or baby oil as the testing oil. If professional smoke test oil is not available, buy liquid paraffin or baby oil locally. Do not use water or sticky liquid. How Much Testing Oil Should I Add? Add 10-15ml testing oil before use and do not overfill. Refill only when the smoke becomes thin, and do not add more than 15ml at one time. Before adding fresh oil, drain remaining old oil from the detector. If too much oil is added accidentally, drain some oil out before operation. Can SDT203 Detect EVAP System Leaks? Yes. AUTOOL smoke leak detectors can test leaks in EVAP systems. Use the proper EVAP testing tools and adapters according to the package contents and the vehicle test port. Can SDT203 Directly Test Automotive A/C System Leaks? No. Automotive A/C systems are high-pressure systems, while SDT203 is a low-pressure smoke leak detector with <15psi rated output pressure. It cannot directly pressure-test the automotive A/C system for leaks. It can only be used for segment-assisted A/C pipeline observation under proper conditions. How Can Smoke Be Used For Segmental A/C Pipeline Auxiliary Testing? First pressurize the air-conditioning pipeline using the proper method, then spray smoke along the pipeline and observe whether airflow blows the smoke. If smoke is disturbed by airflow, that location may indicate a leak point for further inspection or repair. What Systems Can SDT203 Test? SDT203 supports low-pressure leak checks for EVAP, intake, exhaust, fuel tank, car sealing, engine airtightness, and various pipe fitting systems when the test point can be sealed safely. What Power Supply Does SDT203 Need? SDT203 uses DC 12V vehicle battery power. Connect the red clamp to positive ( ) and the black clamp to negative (-). A fully charged 12V vehicle battery is recommended for consistent performance. Can The Pressure Of SDT203 Be Adjusted? Most AUTOOL smoke leak detectors use fixed pressure. SDT203 has a flow adjustment knob for airflow control, but it is not a full adjustable-pressure model. SDT MASTER is the model that allows pressure adjustment. What Accessories Are Included? Refer to the Packing List image for final package contents. The SDT203 package image shows the main unit, retail box, 12V battery clamp cable, smoke hose, cone adapter, airbag adapter, hook, funnel, adapter shown in the package image, and user manual. Testing oil is not included. What Is The Difference Among AUTOOL Smoke Leak Detector Models? SDT103 is EVAP-focused and uses an external air source. SDT106 is a built-in pump beginner smoke mode model. SDT203 is a standard model with built-in air pump, pressure gauge, flow meter window, and flow adjustment knob. SDT205 and SDT205S add air mode and smoke mode. SDT206 uses a built-in dual air pump. SDT208 supports up to 35psi high pressure mode and 10psi low pressure mode. Compare air source, output pressure, output flow, pressure gauge, flow meter, air/smoke mode, oil drain valve, oil level gauge, and accessories before ordering. How Long Is The Warranty For SDT203?
