Foxwell SD201 EVAP Smoke Machine Fuel Oil Pipe Leak Detector DiagnosticTool

The FOXWELL SD201 is a professional automotive smoke leak detector designed to quickly locate leaks in vehicle systems. Equipped with a built-in air pump, adjustable flow meter and advanced smoke generation technology, it helps technicians and vehicle owners identify leaks accurately and efficiently without disassembling large sections of the vehicle.

Whether you are diagnosing EVAP system faults, intake leaks, vacuum leaks or fuel system issues, the SD201 provides a fast and reliable solution that saves both diagnostic time and repair costs.

Why Use a Smoke Leak Detector

• Many vehicle performance problems are directly related to air, vacuum or fuel vapor leaks. Small leaks can trigger warning lights, reduce fuel efficiency and affect overall vehicle performance.

Common symptoms include:

• Check Engine Light
• EVAP System Faults
• Rough Idle
• Engine Misfire
• Reduced Power
• Increased Fuel Consumption
• Vacuum Leaks
• Turbo Pressure Loss
• Fuel Vapor Leaks
• Unusual Noises from Intake or Exhaust Systems

Using a smoke leak detector allows leaks to be identified visually and accurately, making diagnostics faster and more effective than traditional inspection methods.

Built-In Air Pump for Greater Convenience

Unlike many smoke testers that require an external air compressor, the FOXWELL SD201 features an integrated air pump.

Benefits include:

• No external compressor required
• Easy setup and operation
• Portable design
• Suitable for workshop and mobile use
• Convenient for professional technicians and DIY users

This integrated design allows testing almost anywhere without additional equipment.

Accurate Pressure Output:

• The SD201 operates within a stable pressure range of approximately 0.8-1.2 bar.

This pressure range is suitable for most automotive systems and helps:

• Simulate real operating conditions
• Improve leak detection accuracy
• Reduce risk of damage caused by excessive pressure
• Deliver consistent testing results
• Adjustable Flow Meter
• The built-in flow meter helps monitor airflow during testing.

Advantages include:

• Quick confirmation of leak presence
• Better estimation of leak size
• Improved diagnostic efficiency
• Reduced smoke fluid consumption
• Easier system monitoring
• Technicians can use airflow readings together with smoke output to locate leaks faster and more accurately.
• Wide Range of Supported Tests

The SD201 can be used to test a variety of automotive systems, including:

• EVAP System:Detect leaks within the fuel evaporation control system Intake System Identify leaks affecting engine air intake performance.
• Exhaust System:Locate exhaust leaks that may affect emissions and engine operation.
• Turbo System:Check turbocharger hoses and boost-related components.
• Fuel System:Inspect fuel lines and related connections.
• Vacuum System:Detect leaks that may cause idle issues and engine performance problems.
• Crankcase System:Identify sealing problems and pressure-related leaks.
• Cooling System Hoses:Inspect hose connections and sealing integrity.
• Vehicle Cabin Sealing:Evaluate sealing around doors, windows and body panels.
• Advanced Safety Protection:The SD201 incorporates intelligent protection systems for safe operation.

Features include:

• Overheat protection
• Stable operating temperature control
• Automatic shutdown protection
• Enhanced component durability
• Improved operator safety
• These protections help extend equipment life while maintaining reliable performance.

Caution:

1. When you use this Foxwell SD201 Car Smoke Leak Detector for the first time, fill with 10-20ml baby oil. Please be careful NOT to beyond this range.

2. Fresh oil can be filled with only when the smoke gets thin, and it can't be filled over 20ml each time.

3 . Before filling fresh oil, please pour out the left oil in the detector & replace the detector oil regularly.

4. During the process of leak detection, please keep away from smoke-sensitive parts.

5. Do NOT run the detector over 8 minutes continuously. It needs interval rest.

6. The detector has an intelligent protector, if it exceeds the working limit, such as over 75 , it will automatically turn off the power. In this case, please operate it later.

7. The round part of this detector has temperature, please be careful to avoid burns. 8. If the test pipe needs to be disconnected in the middle, please secure the other side with a rubber stopple.
