What Testing Oil Should I Use For SDT102? 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. How Much Testing Oil Should I Add? 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. What Should I Check If SDT102 Does Not Produce Smoke? 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. What Systems Can SDT102 Test? 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. Can SDT102 Detect EVAP Leaks? 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. Can SDT102 Directly Test Automotive A/C System Leaks? 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. How Can SDT102 Assist With Segmental A/C Pipeline Checks? 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. Does SDT102 Need An External Air Compressor? 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. Can The Pressure Of SDT102 Be Adjusted? 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. What Accessories Are Included With SDT102? 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. What Is The Difference Among Various AUTOOL Smoke Leak Detector Models? 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. How Long Is The Warranty For SDT102?
