Before You Order And Use

Before You Order And Use

Read these fluid and compatibility rules before using CT150. The cleaning fluid and the test fluid serve different purposes and must not be mixed or substituted incorrectly.

Use Proper Cleaning Fluid

For ultrasonic cleaning, use professional injector ultrasonic cleaning fluid or professional engine carbon cleaning fluid for better carbon deposit removal.

Use Proper Test Fluid

For 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 Liquid

Corrosive 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 Cleaning

Add 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 Only

CT150 can clean diesel injectors, but it cannot test diesel injectors. Injector testing is intended for gasoline injectors and supported motorcycle injectors.

Confirm Voltage And Language

CT150 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 Reminder

  • Do 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 Features

Key Features

CT150 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 Cleaning

The 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 Testing

The 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 Checks

Supports leakage checking, sprayability testing, spray value comparison, blockage observation, and different operating condition simulation tests.

12 Available Functions

Includes ultrasonic cleaning, idling, medium speed, high speed, accelerating, shifting speed, leak checking, spray value tests, reverse flushing, and no-disassembly cleaning.

Smart Control Panel

The control panel includes function selection, pulse width adjustment, working time / injection count display, start / pause / stop buttons, and pressure adjustment.

Fuse Protection And Support

The 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 Functions

  • No-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.

How To Use

How To Use

Use CT150 to clean injector exteriors, perform ultrasonic cleaning, mount injectors on the flow bench, and run leak, spray pattern, and flow rate tests with the correct fluid.

Clean Injector Exterior

Clean the outside of the injector with cleaning liquid before opening the machine. Place the injectors in the ultrasonic bath after external dirt has been removed.

Run Ultrasonic Cleaning

Add the correct ultrasonic cleaning fluid, then turn on the ultrasonic system so ultrasonic energy can help dislodge particles inside the injectors. After cleaning, recycle the remaining cleaning solution if suitable.

Mount Injectors And Add Test Fluid

Fix the injectors on the main unit. Test for resistance, shorts, and current draw as needed, then add proper injector test fluid to about half of the glass tube.

Run Leak, Spray And Flow Tests

Perform leak testing, spray pattern testing, and flow rate testing on the flow bench. After cleaning, retest the injectors to compare performance before and after service.

Use Notes

  • The cleaning fluid level should not exceed the pulse line connection port during ultrasonic cleaning.
  • Use professional injector test fluid for testing. Do not use corrosive cleaning liquid in the testing system.
  • For testing, secure the injector in the oil separator and add industrial alcohol or professional test fluid to the glass tube as directed.
  • No-disassembly injector cleaning and throttle valve cleaning require extra accessories and extra fees.
  • Keep fluid containers away from flames and monitor the equipment while it is running.
Product Comparison

    It took some figuring out what does what. The four injectors I have are pretty big for street applications so the system has a hard time building any pressure over idle setting. I wish it would come with fluid recommendations. All so found out the ultrasonic bath is heated nothing I read about it said it did. Overall it gets the job done.

  15. Sparky

    I always kept my old injectors and with this tester I was able to reclaim 15 fuel injectors. I was able to clean them up and check the flow meaning I could also flow match them.Some injectors were clogged beyond repair but the 15 I did save more then paid for the cleaner tester machine.I can definitely recommend this Fuel injector Cleaner/tester.

  18. Ken Crosley

    Example: the quality vs time of fluid delivery by the injector changes depending on which position on the manifold it is placed. Totally useless for comparing injectors performance or fuel delivery vs time… like it was designed to do.Injector adapters are cut too long and go too deep into header causing pressure drop. I put a picture of the inside of the header where you can see the adapter threads extend too deep into the header. The LED lights are positioned to shine directly into your eyes. I had to block the LEDs with a piece of card board. Workmanship and quality of materials is very good.

    I was very pleased how the system works! It¡¯s also easy to use. However, the instruction book could use more detail. I really like how I can test the injectors through a variety of speeds.

    This is the second unit I order. The first last me three days and started leaking . The second one I was filling it when it started to leak. No so happy. I need a machine like that for my shop but very disappointed.

    This tool is a great concept, and it really works (the first time) if you’re careful. If carb cleaner touches the plastic electrical pin connectors or the front plastic panel, the plastic of these parts will melt. The manual is poorly written. Critical omissions: It doesn’t tell you how to fill the reservoir; It doesn’t describe the process of dumping the vials after the flow test (that’s what the little handle is for, in the center of the vials); And it doesn’t say how to empty the reservoir after the work is completed (you must tip the unit on it’s side to empty the reservoir). Parts of the tool appear to be well-made, while other parts (e.g., the dump valve for the ultrasonic bath and the aforementioned plastic parts) are really cheap or made of the wrong material. 2 or 3 sets of extra pin connectors should have been provided with the unit, plus 2 or 3 plastic front panels, however, the pin connectors can’t be unplugged. I purchased a used Mercedes wiring harness on Ebay to scavenge the injector pin connectors. I’ll try cutting off the Chinese connectors and splicing on the German connectors, which are solvent-resistant. I love how well this machine worked, but I’ve used it only once. I tried to dump all the carb cleaner from the unit, but it remains to be seen if lingering vapors will damage internal seals. Next time I use it, I’ll update this review.

    Should only be used for cleaning. You do not get any duty cycle information to use for flow testing. Fuel pressure control is extremely poor. Cannot handle low impedance injectors and shuts off when using them. Fluid doesnt come out of the drain port on the back. Sometimes the values on the 2 LCD screens switch places. Injectors flow different amounts depending on which spit they are in. Tons of other issues.

    I like the graduations of the cylinders. I need to use it a few times more to learn its abilities and limitations. Messy when done as solvent leaks out when removing injectors. It can be a bit messy because of that. Not a deal breaker at all though.

    I’ve been using the CT150 Automotive Fuel Injector Tester Cleaner for a few weeks now, and it’s completely changed the way I work in my shop. It’s suitable for both cars and motorcycles, and it’s super easy to use¡ªjust set it up, add the cleaning fluid, and it runs automatically. I also like the built-in safety features; it’s a high-quality tool.

    This is a nice machine for the money. It seems to be made quite well. The instructions seem to be well written and fairly concise. I really like the machines size and it works quite well. Filling the injector cleaner into the machine is something that needs to be watched carefully. The fluid level on the machines side, has fill indications. If you over fill the small internal tank it will leak all over the bench. This machine will give your injectors a good workout and test them well. A machine like this is great to have if you have fuel injected vehicles. If you take your time and do all of the cycles, your injectors (if they are good) will be really clean if the fluid is well chosen .

    The AUTOOL CT150 is incredibly easy to use—simply secure the fuel injector, add the cleaning solution, and press the switch; the device will run automatically. It works for both my car and my motorcycle, but it cannot be used to test diesel injectors or for diagnostic purposes. The safety fuse gives you peace of mind, and its patented technology makes it a reliable tool for both home users and small repair shops!
