Abstract: A system and a method for detecting leaks from a member are disclosed. The system includes the member, a gas source, and a laser vibrometer. The member has an inlet and an outlet and defines a cavity therebetween. The gas source charges the cavity with a gas and continues a flow of the gas into the cavity to maintain the charge. The laser vibrometer detects vibrations caused by the continued gas flow after charging to indicate leakage of the gas from the member.

Abstract: A heat exchanger assembly includes hollow reinforcing members that define openings for receiving supports therein. An end cap is disposed in each open end of cylindrical header tanks and each of the header tanks includes a tubeless length (X) extending inwardly a predetermined distance from each end cap. An inlet and an outlet are disposed in a tubeless length (X). The ends of the reinforcing members extending over the tubeless lengths (X) of the header tanks which include a slot outside each end cap with a tab extending from each end of reinforcing members and into the adjacent slot. All of the components are brazed together in one operation.

Abstract: A fan motor support, for use in combination with a motor vehicle radiator of the type having a U-shaped channel extending along an upper side of the radiator, having a motor mounting portion, a support structure and a claw portion. The motor mounting portion has a motor opening therethrough. The support structure is configured to extend across a portion of a rear surface of the radiator. The claw portion extends from the support structure and has a first member configured to reside in the U-shaped channel.
