A fan ( 16 ) draws air through a core ( 14 ) of a radiator ( 10 ) to which coolant from coolant passages in an engine ( 12 ) rejects heat. A shroud ( 28 ) having first and second parts ( 30, 32 ) in axial succession channels air that has been drawn through the core toward the fan. The first part ( 30 ) is a non-elastomeric ring, and the second part ( 32 ) has an elastomeric ring ( 34 ) having opposite axial ends, one of which telescopically fits to the non-elastomeric ring of the first part ( 30 ) and the other of which joins with a second non-elastomeric ring ( 36 ).
