I have a 1970 Fiat Spider 850 Sport, keeps putting fluid from the radiator into the coolant bottle when it gets hot. Has reached temp of 220F when doing 60 mph.. I can maintain speed of 45 mph and it doesn't get hot. Stays 190F .....We removed the thermostat and it still does this. Can anyone tell me why! Car has less than 10,000 miles and has been garaged for all of it's life. Please help!
