AUTOOL C100 · On-Vehicle Fuel and Intake Cleaning Kit
Clean Supported Petrol Fuel and Intake Paths On-Vehicle
Clean supported petrol EFI circuits without removing the injector assembly, using regulated detergent delivery through the selected service path. The gauge, regulating valve and integrated vessel support vehicle-side control, while the hose, coupling, nozzle and adapter set covers varied petrol-car and light-truck connections. Dedicated setups also support compatible throttle, intake and manual-defined TWC-related procedures.

Key Features
Adapters and Fluid Paths for Several On-Vehicle Tasks
On-Vehicle Fuel-Circuit Flushing
The C100 on-vehicle fuel injection cleaning kit routes detergent through supported petrol EFI injectors, fuel lines, throttle-related passages, and other fuel-system components without removing the injector assembly.
Throttle Cleaning Support
The included spray-nozzle setup supports the manual-defined low-pressure throttle procedure.
Intake-Manifold Procedure
The TWC joint and intake-vacuum connection support the manual-defined gradual detergent-feed procedure.
TWC-Related Cleaning Support
C100 includes joints for the TWC-related flushing workflow described in the manual; it does not guarantee an emissions result.
Adjustable Pressure
The pressure gauge and regulating valve set delivery pressure to support detergent sprayability and controlled cleaning through the selected service path.
Multi-Adapter Coverage
Hoses, couplings, plugs, clamps, nozzles, and vehicle adapters support many European, Asian, and US petrol cars and light trucks when fitment is confirmed.
Portable Integrated Vessel
The bottle body combines fluid storage, gauge, pressure regulation and controlled output for vehicle-side service.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
Safety & Compatibility
Match Vehicle Procedure, Fluid, Pressure, and Adapter
Petrol-System Boundary
Use C100 for confirmed petrol EFI applications. Do not assume diesel, true high-pressure GDI testing or universal fuel-system compatibility.
External Air and Correct Pressure
Use regulated compressed air and the vehicle/procedure-specific setting; never apply a pressure merely because the gauge can display it.
Fuel and Detergent Leak Control
Stop the engine immediately if leakage is found. Do not resume until the connection has been made safe.
Fire and Splash Protection
Keep ignition sources away, control open-line splash with suitable absorbent material, have appropriate fire protection available and wear eye, hand and protective clothing.
Exhaust Ventilation
Route exhaust outdoors and secure the vehicle in neutral or park with the brake applied during an engine-running procedure.
Detergent Compatibility
Use only the detergent specified for the chosen cleaning path and follow its SDS, handling and disposal instructions.
Pressure Release
Relieve bottle and hose pressure before opening the vessel or disconnecting any fitting.
Throttle Relearn
After throttle cleaning, follow vehicle service information for throttle-position initialization or scan-tool relearn when required.
Wear Protective Clothing
Wear protective gloves and protective clothing when operating the cleaner.
Verify Leak-Free Connections
Check every connection point before starting the engine; there must be no leakage during cleaning.
Depressurize Before Disconnecting
Drain the pressure in the C100 bottle after flushing before disconnecting the cleaner.
Restore and Recheck Pipes
Restore all fuel system pipes after cleaning and confirm there is no leakage.
Protect and Store the Housing
Avoid rubbing the sheet-metal housing against rough surfaces. Store C100 dry and away from hot, humid, or poorly ventilated locations.

FAQs
System, Fluid, and Adapter Questions
Is C100 an off-vehicle injector test bench?
No. It is an on-vehicle cleaning kit and does not measure individual injector flow, spray or leakage.
Which vehicles can I service?
C100 is intended for supported petrol EFI cars and light trucks. Confirm the exact fuel-system layout and adapter; do not assume diesel compatibility.
Does The C100 Need An External Air Source?
Yes. AUTOOL C100 requires a suitable regulated external compressed-air source connected to the cleaner air port and adjusted for the target cleaning system.
What Pressure Should I Use For EFI Fuel System Cleaning?
The EFI procedure uses about 40–50 PSI, also described as about 0.3–0.4 MPa, while throttle-style work uses 1–5 PSI. Confirm the correct setting for the vehicle and task, and check for leakage before starting the engine.
What Should I Do If The Vehicle Has No Fuel Return Hose?
For a no-return setup, follow the manual and vehicle service information to disable the fuel pump and use the correct stopper or adapter for the fuel-system layout.
Can C100 clean the throttle and intake?
Yes, with the dedicated throttle nozzle or intake-vacuum procedure. Use the correct detergent, connection, low-pressure setting and current instructions.
Does TWC cleaning guarantee an emissions result?
No. C100 supports the cleaning procedure. Evaluate catalyst condition and emissions compliance with the applicable vehicle tests.
Why might a throttle relearn be needed?
The manual warns that throttle-position initialization may be required after cleaning to prevent a warning light or stored DTC. Follow vehicle service information.
What warranty is stated?
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
Is AUTOOL C100 Suitable For Diesel Vehicles?
C100 is intended for the petrol / gasoline EFI applications described on this page. Ask AUTOOL to confirm suitability before using it on another fuel-system type.
What Pressure Should I Use For Throttle Or Carburetor Style Cleaning?
For throttle style cleaning, adjust the air source pressure to about 1-5 PSI. The manual also gives a carburetor fuel system reference of 0.07-0.35kgf/cm². Use low pressure and confirm the connection before opening the cleaner outlet.
How Do I Identify The Fuel Inlet Hose And Return Hose?
Generally, the inlet hose is larger and the return hose is smaller. A filter is often connected on the inlet hose side, while a buffer is often on the return side. Some hoses also have arrows showing fuel flow direction.
What Should I Check Before Starting The Engine?
Check every connection point and make sure there is no leakage. Keep a fire extinguisher nearby, lead exhaust outdoors, place the transmission in neutral, apply the brake, and stop the engine immediately if any fuel leak is found.
Do I Need To Initialize The Throttle After Cleaning?
The manual warns that the throttle position sensor must be initialized with an automotive scan tool after throttle cleaning. Otherwise, the fault indicator lamp may turn on and the PCM may record a DTC.
