Engine Pressure Loss Tester, Dual Gauge Diagnostic Tool for Checking Leakage Rate Pressure with Extension Rod

It is used to detect many common engine errors, such as piston ring wear, cylinder head breakage, valve wear and cylinder head gasket breakage. It is very suitable for testing trucks and models with minimal spacing. Check the four-stroke engine leak. Based on a common set (1 piece double maniflod pressure gauge, 1 piece rubber hose and 2 pieces metal adapters included), this 3-in-1 cylindrical pressure gauge diagnostic tool adds 2 pieces of universal connectors, 2 pieces of threaded adapters, 1 piece of M14 extension rod and 1 piece of extension hose. Remove the Schrader valve and close the regulator before using workshop air. Install the hose on the cylinder, install the device on the air source, calibrate the leak meter and attach the device to the cylinder hose. Conduct the diagnosis by observing the amount of leakage displayed on the cylinder leak gauge and listen to the leak at each point of the vehicle system.
