Radiator arrangement

A radiator arrangement for water cooled combustion engines, especially for commercial vehicles having an upper and lower water box and a cooling block, wherein said cooling block includes a plurality of tubes for communicating fluid flow between said upper and lower water boxes, the improvement comprising:

• said upper and lower water boxes being formed of a plastic material having cylindrical bores therethrough at each corner of said water boxes;
• a pair of lateral support parts for fixedly attaching said upper and lower water boxes to the respective upper and lower portions of said cooling block, said lateral support parts including fastening flanges at the end of each lateral support part for laterally strapping to said upper and lower water boxes, said fastening means having like bores which align with said bores of upper and lower water boxes for providing a cylindrically continuous opening through which a smooth aligning pin can extend therethrough, thereby connecting said lateral support parts with said water boxes so that the combination thereof holds said cooler block between them, said lateral support parts further including a vehicle frame means for connecting said radiator arrangement to a vehicle frame.
