Can anyone help, my Little Acty van shows a blue temp ( cold light) on start up. After a while this light goes out as it should to indicate normal operating temp. After driving for a while the red light flashes up intermittently. The rad is full and the header tank is correctly filled. If I blip the throttle there is a slooshing noise underneath how do I bleed the system theres two valves under the engine hatch which look pressurised can anyone help Post thread should say Honda Acty 2006
