The cleaning fluid and the test fluid serve different purposes and must not be mixed or substituted incorrectly.Use Proper Cleaning FluidFor ultrasonic cleaning, use professional injector ultrasonic cleaning fluid or professional engine carbon cleaning fluid for better carbon deposit removal.Use Proper Test FluidFor injector testing, use professional automotive injector test fluid. If it is not available locally, 75% medical alcohol may be used as an alternative.Do Not Test With Cleaning LiquidCorrosive cleaning liquid can damage internal components, corrode rubber parts, and cause leakage. Do not use cleaning fluid as the injector test fluid.Add Fluid Before Ultrasonic CleaningAdd the correct ultrasonic cleaning fluid before running the ultrasonic function. Do not run the ultrasonic tank dry, because this may damage the ultrasonic board.Diesel Injectors: Clean OnlyCT150 can clean diesel injectors, but it cannot test diesel injectors. Injector testing is intended for gasoline injectors and supported motorcycle injectors.Confirm Voltage And LanguageCT150 is available for 110V / 220V power environments and has Russian and English versions. Confirm the correct voltage plug and language version before ordering.Fluid Safety ReminderDo not use gasoline as a testing fluid.Do not mix cleaning fluid and testing fluid.Fluids can be flammable; keep away from open flames.The equipment must be monitored during operation.If testing a single injector, plug the other three cylinders. CT150 comes with three plugs for this purpose.Key FeaturesKey FeaturesCT150 combines ultrasonic cleaning, 4-cylinder injector testing, visual spray comparison, adjustable test parameters, pressure observation, and protection design in a compact injector service machine.Ultrasonic Injector CleaningThe ultrasonic tank helps remove carbon deposits from injectors. It can clean petrol injectors and can also clean diesel injectors, but diesel injectors cannot be tested on CT150.4-Cylinder Visual TestingThe 4-cylinder design allows up to four injectors to be tested together, helping users compare spray pattern, spray volume, and injector condition more clearly.Leak, Spray And Flow ChecksSupports leakage checking, sprayability testing, spray value comparison, blockage observation, and different operating condition simulation tests.12 Available FunctionsIncludes ultrasonic cleaning, idling, medium speed, high speed, accelerating, shifting speed, leak checking, spray value tests, reverse flushing, and no-disassembly cleaning.Smart Control PanelThe control panel includes function selection, pulse width adjustment, working time / injection count display, start / pause / stop buttons, and pressure adjustment.Fuse Protection And SupportThe internal fuse can trip during short-circuit conditions to stop the machine. AUTOOL provides 3-year support for eligible non-human damage cases.Accessory-Dependent FunctionsNo-disassembly injector cleaning requires an extra accessory and extra fee.No-disassembly throttle valve cleaning requires an extra accessory and extra fee.Motorcycle injector testing is for supported HONDA, YAMAHA, SUZUKI, and SANYANG injectors only and may require extra accessories.CT150 is suitable for 12V gasoline injectors. For GDI high-pressure injectors, choose CT400, CT450, CT500, FN606, or FN608 based on compatibility needs.

Email[email protected] WhatsApp 86 189 2647 7404Questions And AnswersThese answers cover CT150 injector compatibility, diesel injector limits, cleaning fluid, test fluid, ultrasonic use, parameter settings, no-disassembly functions, model differences, accessories, voltage version, and warranty support. What Is AUTOOL CT150 Used For? AUTOOL CT150 is used to clean and test 4-cylinder gasoline fuel injectors for cars and motorcycles. It supports ultrasonic cleaning, sprayability testing, spray value comparison, leak checking, flow observation, and operating condition simulation tests. Can CT150 Clean And Test Diesel Injectors? CT150 can clean diesel injectors, but it cannot test diesel injectors. Diesel injector testing is not supported on CT150. What Cleaning Fluid Should I Use? For ultrasonic cleaning, use professional injector ultrasonic cleaning fluid or professional engine carbon cleaning fluid. To achieve the intended cleaning effect, a professional syringe / injector ultrasonic cleaning fluid is recommended. If it is not available locally, 75% medical alcohol may be used as an alternative, but the cleaning effect may be weaker. What Test Fluid Should I Use? The test fluid is used to assess injector performance and simulate working states. For consistent testing results, use professional automotive injector test fluid. If it is not available locally, 75% medical alcohol may be used instead of test fluid. Can I Use Cleaning Liquid To Test Injectors? No. Do not use cleaning liquid to test injectors. Corrosive cleaning liquid may damage the equipment, corrode rubber parts, and cause leaks. If the equipment is damaged by using cleaning fluid during injector testing, repair costs may be the user’s responsibility. What Should I Know Before Using The Ultrasonic Cleaning Function? Add the correct cleaning fluid before running ultrasonic cleaning. Do not run the ultrasonic tank without fluid, because this may damage the ultrasonic motherboard. During cleaning, the cleaning fluid should not exceed the connection port of the pulse line. How Do I Set CT150 Test Parameters? You do not need complex settings. Select the feature number and set the test time or injection count according to the function. The testing process is designed to be simple and easy to use. What Is The Difference Between CT150, CT160, And CT200? CT150 and CT160 are both designed for cleaning and testing 4-cylinder gasoline engine injectors. The main difference is that CT160 adds ultrasonic heating, while CT150 does not have this feature. Compared with CT150, CT200 adds two more testing cylinders, supporting 6 injectors in total, while the other basic functions remain similar. When Should I Choose CT400, CT450, CT500, FN606, Or FN608 Instead? If you only need a tester for 12V gasoline fuel injectors, CT150 or CT160 can be suitable. If you need to test GDI high-pressure injectors or require wider compatibility, choose CT400, CT450, CT500, FN606, or FN608 according to injector type, cylinder capacity, voltage settings, heating requirement, pump configuration, and workshop workload. What Is The Difference Between CT200 And CT400? CT200 is mainly for standard 12V fuel injectors and supports 6-cylinder testing. CT400 supports a wider range of injectors, including standard injectors and GDI-related applications, and includes a drawer for injector adapters and accessory storage. Choose CT400 if you need broader injector compatibility and better accessory organization. What Is The Difference Between CT400, CT450, And CT500? CT450 adds the Pulse Injection Test compared with CT400. CT500 further adds Wide Pulse Injection Test and Continuous Injection Test compared with CT450, offering more advanced injector testing options. For cleaning, CT450 includes ultrasonic heating up to about 50°C, while CT400 and CT500 do not have the same heating function. How Is FN608 Different From FN606 And CT500? FN608 supports 8-cylinder testing, while FN606 and CT500 support 6-cylinder testing. FN608 has two independent fuel pumps, each corresponding to a separate fuel rail, so if one pump fails, only the corresponding rail is affected while the other can continue operating. Compared with CT500, FN608 also offers a heating cleaning tank up to about 50°C, wider voltage ranges, and a cleaning tank design that can be used independently or together with the main unit. Does CT150 Support No-Disassembly Cleaning? CT150 can support no-disassembly injector cleaning and no-disassembly throttle valve cleaning, but these functions require extra accessories and extra fees. Confirm accessory availability before ordering if these functions are important for your workflow. What Accessories Are Included With CT150? Refer to the Packing List image for the final package contents. The package includes the CT150 main unit, retail box, manual, power cable, signal wires, oil rail / pressure gauge assembly, funnel, drain valve, adapters, plugs, O-rings, and other fittings shown in the package image. What Voltage And Language Versions Are Available? CT150 supports 110V / 220V ±10%, 50Hz / 60Hz power environments. It has Russian and English versions. Confirm the required voltage plug and language version before ordering. How Long Is The Warranty? AUTOOL provides 3-year warranty support for eligible damage caused by non-human factors. For eligible cases, AUTOOL may provide replacement parts or support according to the after-sales policy.Related GuidesRelated GuidesUse these related articles to understand injector cleaning results, higher-end injector tester comparisons, and GDI fuel injector cleaner model selection.
