A vehicle comprising: a coolant header tank 12 having a minimum fluid level 32, the coolant header tank comprising a port 30 connected to the portion of the header tank that contains fluid when filled to the minimum fluid level and; a temperature regulating system 7 comprising an air collecting region 18 which is connected to the coolant header tank 12 to permit air flow from the temperature regulating system 7 to the coolant header tank 12. The temperature regulating system is configured so that the air collecting region is higher than a horizontal plane defined by the minimum fluid level 32. The temperature regulating system 7 may comprise a first and second heat exchanger 9, each with an air collecting region 18, which are connected to the header tank 12. The temperature regulating circuit 7 may also comprise a cooling circuit 8 connecting the heat exchangers 9 to a powertrain 5. The horizontal plane of the minimum fluid level 32 may be located below an air collecting region 20 of the powertrain 5.
