The Lang Tools Three-way Exhaust Back Pressure Kit (TU24APB) is an essential diagnostic tool designed to help automotive technicians swiftly and accurately pinpoint exhaust system restrictions. It’s engineered to provide precise measurements of back pressure, aiding in the identification of clogged catalytic converters, restricted mufflers, and other flow impediments that can negatively impact vehicle performance and fuel efficiency.
KEY FEATURES AND BENEFITS:
Three-Way Testing Capability: Offers the flexibility to connect and test in three crucial areas: the Oxygen Sensor ports (with 12mm and 18mm threads), directly on Exhaust Pipes, and within the Air Injection System. This comprehensive approach allows for thorough diagnosis and isolation of blockages.
Specialized Dual-Band Gauge: Features a 2-1/4 inch diameter gauge with unique multicolored bands. These bands simplify the interpretation of pressure readings at both idle and 2500 RPM, allowing for dynamic assessment of exhaust flow. The gauge displays measurements in both PSI and Bar.
Protective Gauge Boot: The gauge is encased in a rubber boot, providing essential protection against impacts and damage in a workshop environment, thus extending the tool’s lifespan.
Extended Hose Length: Includes a generous 6-foot hose, enabling technicians to comfortably perform tests and observe readings from the driver’s seat, enhancing convenience and efficiency during diagnosis.
Durable Storage Case: Comes with a custom-fit plastic blow-mold case, ensuring organized storage and protection for all kit components when not in use.
SPECIFICATIONS:
Part Number: TU24APB
Gauge Diameter: 2 1/4 inches
Hose Length: 6 feet
Included Components: 2 1/4 inch pressure gauge with protective boot, 6-foot hose, 12mm and 18mm adapters for O2 sensor ports, components for testing exhaust pipes and air injection system, plastic blow-mold storage case.
HOW TO USE:
Prepare the Vehicle: Ensure the engine is at normal operating temperature. For safety, park the vehicle on a level surface and engage the parking brake.
Select Test Point: Choose one of the three available test points:
Oxygen Sensor Port: If using an O2 sensor port, carefully remove the oxygen sensor and select the appropriate 12mm or 18mm adapter from the kit. Thread the adapter into the O2 sensor bung.
Exhaust Pipe: For testing directly on an exhaust pipe, use the provided adapter and clamp it securely to the exhaust pipe, ensuring a tight seal.
Air Injection System: If applicable, connect the kit to a suitable access point in the vehicle’s air injection system.
Connect Gauge Assembly: Attach the 6-foot hose to the selected test point adapter, ensuring a secure connection. Connect the other end of the hose to the 2-1/4 inch pressure gauge.
Perform Idle Test: Start the vehicle’s engine and let it idle. Observe the gauge reading on the “Idle” colored band. Note the pressure in PSI or Bar.
Perform 2500 RPM Test: While observing the gauge from the driver’s seat, carefully increase the engine RPM to 2500 RPM and hold it steady. Observe the gauge reading on the “2500 RPM” colored band. Note the pressure in PSI or Bar.
Interpret Readings: Compare your recorded readings to the vehicle’s service manual specifications or general guidelines for acceptable exhaust back pressure. Abnormally high readings, especially at 2500 RPM, indicate a restriction in the exhaust system.
Disconnect and Store: Once testing is complete, carefully disconnect the kit components, replace any removed sensors, and store all parts in the provided blow-mold case.
