Embarrasingly, I didn't realise that my mum's Clio has power steering. Anyway, it's stopped working 'cos the fluid level is low. I know sweet FA about power steering so if anyone could point me towards the type of stuff I need to top it up I'd be grateful.....that is if allowing the fluid to run low hasn't killed it. Is it a specific type of fluid? Or do you use DOT-4 clutch/brake fluid or something?
