OKSTENCK Turbo System Leakage Tester Kit，9-Piece Turbocharger System Leak Detection Instrument 1-3/8‘ to 3-1/2’ for Turbo Leak Detection of Cooling Exhaust Pipes — Open-Box, 27% Off

Pinpointing: This kit allows you to quickly locate leaks in your turbo system. Simply plug the intake and exhaust ports, connect to the air compressor via the regulator, and pressurize the turbo system. Once pressurized, you can quickly locate the leak by watching the gauge to see if it maintains pressure and listening for leaks. Simple operation: Simply connect the adapter, connect the gauge to the shop air line, pressurize the system, then watch the gauge to see if it maintains pressure and listen for signs of leaks. If you notice a drop in pressure, you can easily locate the leak by hand or with a spray. If the pressure is too high, simply pull the red overpressure relief valve to reduce air pressure. COMPATIBLE: This kit comes with 4 pairs of stepped adapters with adapters ranging from 13.78'' (35 mm) to 35.43'' (90 mm) for most car and light truck turbo systems. WIDE FUNCTION: This turbo leak tester is not only suitable for turbocharging system, but also can be used for cooling system and emission system leakage detection, which makes you more comfortable in the maintenance and repair process, saving time and cost. Whether it is a private car or a light truck, it can be easily dealt with, and it is the right assistant for your vehicle maintenance. Kit includes: one pressure gauge (including valve, quick air connection), 4 pairs of step adapters (35 mm - 90 mm)，3pcs air fittings(1/4'' NPT US type/European type/Japanese type).

Operating Procedure:

1. Select the correct adapter, set the regulator of the tester to 5psi to check whether the valve is open and whether there is any air leakage, disconnect the air connector.

2. Put the adapter into the hose, tighten the clamps, link the air connector, and check for air leakage at the preset pressure of 5psi.

3. If there is a sound of air leakage, this indicates a fault in the system unity, resulting in a loss of pressure. If no leaks are evident, adjust pressure to 10 psi and check again. If there is still no air leakage at 10psi, continue to adjust the pressure to a maximum of 15psi, or to the maximum pressure recommended by the manufacturer, and retest.

4. If the pressure gauge needle remains constant for one minute, the system is working properly. Relieve pressure in the system by rotating the ball valve stem to align it with the hose axis.

5. Disconnect the quick disconnect, clean all items and return them to the carrying case.
