Confirm the exact fuel-system layout and adapter; do not assume diesel compatibility.<\/p><\/div><\/details><details><summary>Does The C100 Need An External Air Source?<\/summary><div class=\"autool-faq-answer\"><p>Yes. AUTOOL C100 requires a suitable regulated external compressed-air source connected to the cleaner air port and adjusted for the target cleaning system.<\/p><\/div><\/details><details><summary>What Pressure Should I Use For EFI Fuel System Cleaning?<\/summary><div class=\"autool-faq-answer\"><p>The EFI procedure uses about 40\u201350 PSI, also described as about 0.3\u20130.4 MPa, while throttle-style work uses 1\u20135 PSI. Confirm the correct setting for the vehicle and task, and check for leakage before starting the engine.<\/p><\/div><\/details><details><summary>What Should I Do If The Vehicle Has No Fuel Return Hose?<\/summary><div class=\"autool-faq-answer\"><p>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.<\/p><\/div><\/details><details><summary>Can C100 clean the throttle and intake?<\/summary><div class=\"autool-faq-answer\"><p>Yes, with the dedicated throttle nozzle or intake-vacuum procedure. Use the correct detergent, connection, low-pressure setting and current instructions.<\/p><\/div><\/details><details><summary>Does TWC cleaning guarantee an emissions result?<\/summary><div class=\"autool-faq-answer\"><p>No. C100 supports the cleaning procedure. Evaluate catalyst condition and emissions compliance with the applicable vehicle tests.<\/p><\/div><\/details><details><summary>Why might a throttle relearn be needed?<\/summary><div class=\"autool-faq-answer\"><p>The manual warns that throttle-position initialization may be required after cleaning to prevent a warning light or stored DTC. Follow vehicle service information.<\/p><\/div><\/details><details><summary>What warranty is stated?<\/summary><div class=\"autool-faq-answer\"><p>Main unit: 3-year warranty.

Ask AUTOOL to confirm suitability before using it on another fuel-system type.<\/p><\/div><\/details><details><summary>What Pressure Should I Use For Throttle Or Carburetor Style Cleaning?<\/summary><div class=\"autool-faq-answer\"><p>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\/cm\u00b2. Use low pressure and confirm the connection before opening the cleaner outlet.<\/p><\/div><\/details><details><summary>How Do I Identify The Fuel Inlet Hose And Return Hose?<\/summary><div class=\"autool-faq-answer\"><p>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.<\/p><\/div><\/details><details><summary>What Should I Check Before Starting The Engine?<\/summary><div class=\"autool-faq-answer\"><p>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.<\/p><\/div><\/details><details><summary>Do I Need To Initialize The Throttle After Cleaning?<\/summary><div class=\"autool-faq-answer\"><p>The manual warns that the throttle position sensor must be initialized with an automotive scan tool after throttle cleaning.
