Just of late I have noticed that the engine water temp has been a bit funny.When I am driving along the temp is fine at about 82deg but when I slow down for traffic or join a queue for more than a couple of mins the temp starts to rise fairly quick and after about 5 min its nearly hitting the red and water is been ejected through the radiator cap vent.As soon as i move off into free flow traffic it goes down to normal operating temp (82deg).I have checked the internal heaters and they blow hot air when needed and there is water in the radiator Has anyone got any ideas.cheers
