Cooler fastening system

In a power system having an engine, heat exchanger structure comprising at least one generally flat heat exchanger mounted in fixed relationship to said engine for cooling liquid associated with said engine, and a generally flat oil cooler structure for cooling oil associated with said engine, said structures being of the type having fins and perforations arranged generally normal to the general planes thereof,

• a fastening system for mounting said oil cooler structure in stacked relationship on one side of said heat exchanger structure, which comprises
• an elongated, thin, generally straight tension member which is sufficiently long and thin to extend through perforations in said structures and to project beyond the free sides of the structures in stacked relationship,
• said tension member having substantial column strength and being generally rigid against gross lateral bending in all lateral directions so as to enable it to be pushed through said structures in stacked relationship,
• a pair of abutment members adapted to be secured at spaced positions along the length of said tension member on opposite free sides of said structure in stacked relationship,
• at least one of said abutment members being longitudinally movable on said tension member toward the other abutment member into a tensioning position of the fastening system wherein said tension member is placed under tension between said abutment members,
• and locking means engageable between said movable abutment member and said tension member for locking them in said tensioning position.
