Hello i hope this isn't in the wrong forum or has already been answered but i recently brought my son a seicento 2001 1.1cc and it seems its to be lighter to steer to the left than it does to the right (as well its still over heating in traffic but i think thats due to the fan not working or maybe the water pump as the head gasket and the thermostat have been done and its been bled) but my main concern is the steering any ideas what it could be anyone , i have read they have electric power steering and that it plays up and even heard it can lock up completely causing the car to left steering the way it locked up, this is a big concern

Yup, like most problems this has been covered many times -but on your first post you aren't expected to know this https://www.fiatforum.com/cinquecento-seicento/358526-power-steering.html?358526=#post3556137
On the main page if you enter 'power steering' where it says 'Search this Forum' it will come up with lots of posts with similar issues (so you're not alone & it is fixable). Best of luck with it.

sorry about that and cheers bud
