Step-by-step injector service workflow
Step-by-Step Workflow
Clean the injector exterior, run ultrasonic cleaning with the approved fluid, install the injectors, then perform leak, spray-pattern, flow, simulated operating, and reverse-flush tests.
01
Step 01
Pre-Clean Injector Exterior
Clean the outside of the injectors with suitable gasoline or cleaning liquid before turning on the machine so loose dirt does not contaminate the tank or test system.
02
Step 02
Add Ultrasonic Injector Cleaning Fluid
Pour the proper ultrasonic cleaning fluid into the cleaning tank, then place the injectors in the bath after exterior dirt is removed.
03
Step 03
Connect Pulse Signal And Clean
Connect the pulse signal wire and select ultrasonic cleaning so vibration can dislodge particles and carbon buildup inside the injectors.
04
Step 04
Install Injectors On The Main Unit
Pour in proper test fluid, install the injectors on the fuel distributor or rail, and secure the assembly to the main unit with bolts.
05
Step 05
Run Injector Tests
Run leakage, spray-pattern, flow-rate, idle, medium-speed, high-speed, acceleration, shifting, and reverse-flushing tests using the selected function and time.
06
Step 06
Retest And Compare
After cleaning, repeat the required tests and compare spray pattern, measuring-tube level, leakage, and flow consistency.
Result interpretation
How To Read Test Results
Use the same pressure, test time, pulse setting, fluid, injector mounting, and operating mode for every injector. Follow the table from spray observation through before-and-after confirmation so each result leads to a defined cleaning, retest, diagnosis, or replacement action.
| What You Observe | What It May Mean | Recommended Next Step |
|---|---|---|
| Drips while closed | Contamination, valve-seat wear, or a sealing fault | Clean and re-test; refer or replace if leakage remains |
| One measuring cylinder fills much less | Restriction, installation leak, channel issue, or injector fault | Check pressure and sealing, swap channels, then clean and repeat |
| Deflected, split, coarse, or dripping spray | Deposit, nozzle damage, or internal mechanical issue | Clean and re-test; use specialist service if unchanged |
| Difference becomes smaller after cleaning | A recoverable restriction may have been reduced | Record the result, renew applicable seals, and verify on the vehicle |
| No measurable improvement | The injector may already be clean or have electrical / mechanical damage | Stop repeated cleaning and continue diagnosis, specialist testing, or replacement |
| Bench results look balanced but the vehicle still misfires | The root cause may be outside the injector system | Check ignition, compression, intake leakage, fuel pressure, and control signals |
Important: Confirm any abnormal result by repeating the same test before changing settings. Keep ultrasonic cleaning fluid in the cleaning tank and non-corrosive test fluid in the test circuit. Use the injector specification, service procedure, or CT200 manual for final acceptance limits.
Fluid, compatibility, and operating limits
Safety & Compatibility
Before using CT200, confirm the injector type and prepare the correct ultrasonic cleaning fluid and injector test fluid. Cleaning fluid and test fluid must not be mixed or used in the wrong circuit.
Use Professional Cleaning Fluid
Use professional fuel injector cleaning fluid formulated for ultrasonic tanks or professional engine carbon cleaning fluid to remove carbon deposits and impurities.
Use Professional Test Fluid
Use colorless, odorless, non-corrosive professional fuel injector test fluid to simulate injector operating conditions safely.
75%+ Medical Alcohol Backup
If professional cleaning or test fluid is unavailable locally, medical alcohol above 75% can be used as a temporary alternative, although the cleaning or test effect may not be ideal.
Do Not Test With Cleaning Liquid
Do not put corrosive cleaning liquid into the test circuit. It may damage internal components, accelerate rubber deterioration, and cause leakage.
Do Not Run Ultrasonic Cleaning Dry
Add the proper ultrasonic cleaning fluid before running the ultrasonic function. Do not run the ultrasonic tank dry; doing so may damage the ultrasonic system.

Can Diesel Injectors Be Cleaned And Tested With AUTOOL CT Series Products?
AUTOOL CT series products can clean diesel injectors, but they cannot test diesel injectors. Use CT200 only within its supported testing range.
How Should I Choose Ultrasonic Cleaning Fluid?
For ultrasonic cleaning, use professional engine carbon cleaning fluid or professional automotive injector ultrasonic cleaning fluid. It helps remove deposits such as carbon buildup from injectors. If professional cleaning fluid is not available locally, 75%+ medical alcohol may be used as a substitute, but the cleaning effect may vary.
How Should I Choose Injector Test Fluid?
For consistent test results, use professional automotive injector test fluid. Test fluid is a colorless, odorless, non-corrosive liquid used to assess injector performance and simulate working states. If professional test fluid is not available locally, 75%+ medical alcohol can be used as a temporary alternative.
Can I Use Cleaning Liquid To Test Injectors?
No. Do not use cleaning liquid in the injector testing circuit. Cleaning liquid may be corrosive and can damage internal parts, accelerate rubber deterioration, cause leakage, and lead to malfunction. Damage caused by using the wrong fluid may require paid repair.
Why Must I Add Cleaning Fluid Before Ultrasonic Cleaning?
The ultrasonic tank must contain the proper cleaning fluid before the ultrasonic cleaning function is started. Do not run the ultrasonic system dry or with unapproved fluid; doing so may damage the system.
Why Does CT200 Come With Five Plugs?
When testing a single injector, plug the other five unused test positions. CT200 comes with five plugs for single-injector testing or partial injector testing.
How Do I Set CT200 Test Parameters?
You do not need special settings for normal operation. Select the feature number and set the test time through the control panel. Select a test mode and set the test time on the control panel.

If one pump fails, only the corresponding fuel rail is affected, while the other side can continue to operate. FN606 uses a single fuel pump, so a pump failure stops the entire system until the pump is replaced.
What Is The Difference Between FN608 And CT500?
FN608 supports 8 cylinders, while CT500 supports 6 cylinders. FN608 has a heating cleaning tank that can maintain up to 50°C, while CT500 does not support heating. FN608 supports 12V, 12-70V, and 120-180V voltage ranges, while CT500 supports 12V, 70V, and 120V. FN608 allows the cleaning tank to operate independently or together with the main unit, while CT500 integrates the cleaning tank into the main body. FN608 also uses two independent fuel pumps, while CT500 uses a single pump.
Which AUTOOL Injector Cleaner Should I Choose If I Need GDI, Heating, 8-Cylinder Testing, Or Dual Pumps?
Choose CT160 for up to four standard 12 V gasoline injectors, or CT200 for up to six. If you need GDI high-pressure injector support, choose CT400, CT450, CT500, FN606, or FN608. For heated ultrasonic cleaning, compare CT160, CT450, FN606, and FN608 based on injector compatibility and capacity. If you need 8-cylinder testing and dual-pump reliability, choose FN608.
What Accessories Are Included With CT200?
Refer to the Packing List image for final package contents. The package includes the CT200 main unit, fuel rail with pressure gauge, signal wires, power cable, funnel, valve, adapters, seals, O-rings, manual, and related accessories. Confirm quantities before ordering.
