ABSTRACT:
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).
