The invention concerns a cooling system pressure testing device for the purpose of leak detection. The device has a bladder with a passage extending therethrough. The bladder may be inflated to lock it within an opening in an object to be pressure tested and once inflated fluid may be passed through the passage to pressurize the object being tested.

A cooling system pressure testing device for attachment in an inlet opening of a component of the cooling system to be pressure tested, the cooling system pressure testing device including a body having an inlet and an inlet valve communicating with the body inlet, a sealing head positionable in the opening and having a support and a bladder having an inlet secured to and extending about the support, a passage extending through the bladder and having an inlet and an outlet, the body inlet and the valve allowing fluid from a single source to be selectively directed to either the passage inlet or the bladder inlet to either pressurize the component to be pressure tested or to inflate the bladder, and a pressure relief valve in communication with the passage for limiting the pressure to which the test is conducted and which is operable to vent the pressure within the component without deflating the bladder whereby the bladder may be inflated to close off the inlet opening and the passage enabling the system to be pressurized up to a pressure determined by the pressure relief valve while the bladder closes off the inlet opening.
