GE-52250 PowerSmoke Diagnostic Leak Detector Shipping Now as Essential Tool

The GE-52250 PowerSmoke Diagnostic Leak Detector (Fig. 1), now an essential tool shipping to all dealerships, can be used to help find induction and exhaust system leaks on 2010-2020 GM models equipped with a turbocharged engine. Leaks in the induction system on turbocharged engines can set a number of DTCs and result in reduced engine power.

Shipments of the GE-52250 PowerSmoke Diagnostic Leak Detector have begun to all U.S. and Canadian dealerships. The tool also will remain in the Loan Tool Program for U.S. dealerships that need to use the tool but have not yet received their shipment.

Tool Operation

To locate the leaks, the GE-52250 tool introduces compressed air and smoke into the system without disassembling a number of components, saving time and reducing the chance of missing a faulty connection. The tool is similar to the EVAP smoke machine, but produces up to 60 times the volume of pressure and smoke.

TIP: Due to the high pressure output produced by the GE-52250 tool, it should not be used to diagnose EVAP system leaks.

On the control panel of the GE-52250 tool, there is a flow control knob that allows the desired air pressure, with or without smoke, to flow through the hose to the vehicle being tested. The tool has a System Pressure gauge, Flow meter, Power indicator, Vapor Test switch, Air Only Test switch, Reset switch, Adjustable Pressure Regulator, and a Test Pressure gauge.

The tool also features a number of multiple adapters, which include several with inflatable bladders that allow one or both ends of the system to be sealed off. The adapters also have a connection point that enables smoke to be injected into the system. The 12 volt, Halogen inspection lamp has a yellow tint to help illuminate the escaping smoke, making it easier to pinpoint leaks.

The tool is activated by selecting either the Vapor Test or Air Only Test. To adjust the output air pressure, pull the regulator knob outward and then turn the knob clockwise to increase pressure and counterclockwise to reduce pressure. The Service Information suggests that the air pressure regulator be set to 5 PSI (34.5 kPa). Higher pressure will generate lower smoke density. As the pressure is decreased, smoke density will increase. Press the Vapor Test button once to begin a 10-minute smoke test; press the button again to stop the test.
