A method of testing an engine aftercooler without removing it from the engine, the method including the steps of exposing the air inlet of the aftercooler, applying a gas under a superatmospheric pressure to the air chamber of the aftercooler, maintaining the gas pressure at a predetermined level, monitoring the liquid in the liquid chamber of the aftercooler, whereby the presence of leaks in the aftercooler can be determined by observing the evolution of bubbles from the liquid in the aftercooler. Testing apparatus for an engine including an aftercooler and a turbocharger, the apparatus including an adapter capable of being operatively connected to the air chamber section of the aftercooler, fasteners engageable with the adapter capable of securing the adapter to the engine, a passage through the adapter, mechanism for supplying a gas under superatmospheric pressure through the adapter, pressure measuring mechanism associated with the gas supplying mechanism, and pressure relief mechanism associated with the gas supplying mechanism, whereby securing the adapter to the engine and supplying gas under superatmospheric pressure through the apparatus to the air chamber of the aftercooler will cause the pressurized gas to be forced through any flaws in the aftercooler and produce bubbles in a liquid medium disposed on the opposite side of the aftercooler from the air chamber.
