Abstract: Vehicle oil, particularly transmission hydraulic fluid, is cooled by circulating the oil from the working component to a heat exchanger submerged in the fuel tank.

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).

Abstract: A vehicle has a fluid center that comprises a cowl tray mounted to the cowl structure of its operator cabin below a lower end of the windshield of the operator cabin. In addition to a cowl tray the fluid center comprises a fluid reservoir and/or a fluid-center-mounted engine-air-intake duct with an inlet that is directly or indirectly in fluid communication the atmosphere and an outlet that is in fluid communication with other engine-air-intake ducts of the vehicle.

Abstract: The invention involves a vehicle with a cab. The environment of the cab may be maintained by a heating, ventilation, and air-conditioning (HVAC) system that will provide cool air to the cab in hot weather and warm air to the cab in colder weather. The HVAC system will have its own specific air heating and cooling components. The HVAC has a supply to the cab for providing the cool or warm air depending on the need. A siphon or alternative point of distribution of the HVAC output may be a HVAC diversion line that leads into the inlet of the turbocharger or supercharger of the vehicle engine to mix with ambient air entering the turbocharger.
