After working fine all day, this afternoon I noticed my engine had heated up so hot the needle was above the red. I pulled over and there was steam coming from a small space on the radiator and it appeared to be 'spitting' anti-freeze.
I let it cool down and checked coolant level which was almost completely empty (not even near minimum) - I don't usually drive this car, and had only been using it for a week so didn't expect this. I had been told that a low coolant level could cause pressure to build up in the radiator and lead to the 'spitting' leakage I had encountered.
So I topped up the coolant and took it for a short test drive, again it heated up with the steam and 'spitting'. I don't know much about cars, is there anything I can try to fix myself or does this need a mechanic to look at it?
Thanks
