AUTOOL CT150 Fuel Injector Tester and Cleaner Machine

AUTOOL CT150 Fuel Injector Tester & Cleaner Machine is a professional 4-cylinder auto fuel injector testing and cleaning machine. It will help us clean and test the injectors of gasoline cars and motorcycles. Support for more cars and motorcycles. It can only be used to clean diesel fuel injectors. The cleaning fluid is a 3M car injector, and the test fluid is industrial alcohol. Its working voltage range is 110- 230V. CT150 Car Fuel Injector Tester Cleaner has two versions: Russian and English. Warm Tips For ultrasonic cleaning fluid, please use professional engine carbon cleaning fluid. Please use professional injector test fluid, as corrosive cleaning fluid will damage the equipment. If you damage the equipment by using cleaning fluid while testing the injector, you will be responsible for the repair costs. When using the ultrasonic cleaning function, please add the transmitter carbon cleaning fluid before running the equipment, please do not add the cleaning fluid directly to open the equipment to run, as it will lead to ultrasonic motherboard damage. How to choose a cleaning fluid? To achieve the best cleaning effect, it is recommended to use a professional syringe ultrasonic cleaning fluid to clean the injector. Or you can use medical alcohol with an alcohol content of more than 75% instead of cleaning fluid, but the cleaning effect may not be good enough. How to choose a test fluid? To achieve the best test effect, recommended to use professional automotive injector test fluids. If it is not available locally, as an alternative, we recommend that medical alcohol with an alcohol content of more than 75% be used instead of the test fluid. When you test a single injector, you simply need to plug only the other 3 cylinders, so the CT150 comes with three plugs. AUTOOL CT150 Manual Download What is the Difference Between the AUTOOL Fuel Injector Cleaner & Tester Machine? FAQs Comparison: AUTOOL FN608 vs FN606 car injector cleaner machine  1. Cylinder Testing Capacity The FN608 supports testing for 8 cylinders, while the FN606 supports testing for 6 cylinders. 2. Pump Configuration The FN608 is equipped with two independent fuel pumps, each corresponding to a separate fuel rail (left and right). Both pumps operate independently during testing — if one pump fails (e.g., the left pump), only the corresponding fuel rail is affected, while the other continues to function normally. This dual-pump system ensures greater reliability and uninterrupted testing. The FN606, on the other hand, has a single fuel pump, meaning that if it fails, the entire system stops working until the pump is replaced. Comparison: AUTOOL FN608 vs CT500 fuel injector tester  1. Cylinder Testing Capacity The FN608 supports testing for 8 cylinders, while the CT500 supports testing for 6 cylinders. This makes the FN608 more suitable for high-capacity or multi-cylinder engine injectors. 2. Heating Function The FN608 features a heating cleaning tank capable of maintaining a constant temperature up to 50°C, which significantly improves cleaning efficiency and performance. In contrast, the CT500 does not support heating, offering a more basic cleaning function. 3. Voltage Settings The FN608 supports multiple voltage ranges — 12V, 12–70V, and 120–180V — making it compatible with a wider variety of injector types. The CT500, however, supports only 12V, 70V, and 120V, providing more limited voltage adaptability. 4. Cleaning Tank Design The FN608’s cleaning tank can be used independently or together with the main unit, providing greater flexibility for maintenance and cleaning. The CT500’s cleaning tank is integrated with the main body and cannot be used separately, limiting its independent operation. 5. Pump Configuration The FN608 is equipped with two independent fuel pumps, each corresponding to a separate fuel rail (left and right). Both pumps operate independently during testing — if one pump fails (e.g., the left pump), only the corresponding fuel rail is affected, while the other continues to function normally. This dual-pump system ensures greater reliability and uninterrupted testing. The CT500, on the other hand, has a single fuel pump, meaning that if it fails, the entire system stops working until the pump is replaced. Comparison: AUTOOL CT400 vs CT450 vs CT500 injector cleaning machine 1. Testing Functions: The CT450 adds the Pulse Injection Test compared to the CT400, while the CT500 further adds Wide Pulse Injection Test and Continuous Injection Test compared to the CT450, offering more advanced and versatile injector testing capabilities. 2. Cleaning & Heating Function: The CT450 features ultrasonic cleaning with heating up to 50°C, whereas the CT400 and CT500 do not have a heating function, making CT450 more effective for thorough injector cleaning. Comparison: AUTOOL CT200 vs CT400 fuel injector cleaner machine 1. Supported Injector Types CT200 only supports 12V standard fuel injectors, whereas CT400 supports both 12V standard and GDI (Gasoline Direct Injection) injectors, making it compatible with a wider range of injector types and vehicles. 2. Accessory Storage Design CT200 does not have dedicated accessory storage, while CT400 features a drawer for injector adapters and other accessories, providing more convenient organization and storage. Comparison: AUTOOL CT150 vs CT160 vs CT200 ultrasonic fuel injector cleaner Both the CT150 and CT160 are designed for cleaning and testing fuel injectors of 4-cylinder gasoline engines. The main difference is that the CT160 is equipped with an ultrasonic heating function, while the CT150 does not have this feature. Compared with the CT150, the CT200 simply adds two more testing cylinders (6 in total), while the other functions remain the same. If you only need a tester for 12V gasoline fuel injectors, the CT160 is an excellent choice. However, if you need to test GDI (Gasoline Direct Injection) high-pressure injectors, we recommend choosing CT400, CT450, CT500, FN606, or FN608 for better compatibility and performance.

How To Use AUTOOL CT150 Fuel Injector Tester & Cleaner Step 1: Clean the injector’s outside with cleaning liquid before opening the machine. Putting injectors in the ultrasonic bathtub after the outside of the injector is free of dirt. The cleaning fluid does not exceed the connection port of the pulse line. Step 2: Turn on the ultrasonic system, allowing the ultrasonic energy to dislodge any particles that build up inside the injectors. After cleaning, you can recycle the remaining cleaning solution. Step 3: Fixed injectors on the main machine, testing injectors for resistance, shorts, and current draw. Add the test solution to half of the glass tube. Step 4: Performing leak test, spray pattern, and flow rate testing on the flow bench. The injectors are now returned to the flow bench for retesting of all functions.

Online Support Packing List FAQs Can diesel injectors be cleaned and tested by using AUTOOL CT series products? AUTOOL CT series products can clean diesel injectors, but not test. How to choose a test fluid? The test fluid assesses the fuel injector’s performance. It is a colorless, odorless, and non-corrosive liquid that simulates various injector working states. For best results, recommended to use a professional automotive injector test fluid. If not available, medical alcohol with more than 75% alcohol content can be used instead. How to choose cleaning fluid? To clean deposits (such as carbon deposits) on fuel injectors, use a cleaning fluid that is highly corrosive and flammable. For the best testing results, opt for a professional injector ultrasonic cleaning fluid. If local options are unavailable, you may use 75% medical alcohol as a substitute, but its effectiveness may vary. Can I use cleaning liquid to test the injectors? Absolutely not! The cleaning liquid is corrosive and may damage internal machine components, corrode rubber, and cause leaks. How do I set test parameters? You don’t need special settings. All you have to do is set the number for the feature and set the test time. The testing process is simple and easy to use. How to select the correct voltage when using CT400 to test GDI injectors? Select the voltage according to the injectors to be tested. Gradually increase the voltage from 12V, 70V to 120V, until the injectors function correctly. When testing GDI injectors with CT400, will the wrong voltage damage the injectors? In the short term, the wrong voltage won’t cause damage. However, do not apply the wrong high voltage to the injectors for a long time. If the injector does not work properly, please adjust it to the correct voltage in time. Related blogs See These Signs?
