Abstract: Cooling apparatus for cooling an engine on a motor vehicle including at least one heat exchanging cooler extending transversely of the motor vehicle and arranged below a storage compartment at one end of the vehicle. To enhance the flow of cooling air through the cooler, an air deflection member is provided adjacent the exit end of the coolers, which deflection member causes a vacuum suction at the exit end of the cooler in response to air flowing past the vehicle at high speed during driving of the vehicle. Adjacent the forward end of the air entrance to the coolers, an upwardly extending opening is provided between an endmost bumper and vehicle body parts forming a tire storage compartment, which upwardly extending opening also creates a vacuum suction effect at the entrance to the coolers in response to air flowing over the outside of the vehicle adjacent the bumper and a hood covering the storage compartment.
