Hi, I have a 2001 Micra (1.0 engine), and I'm about to ask two noob questions, so I apologise in advance. The coolant level is low. I went to halfords and the two types of anti freeze they have one is "Silicate (IAT) based" and the other is "Silicate-free (OAT)" . Which one is most suitable for my Micra?
My other question is can I just top it up or will I have to drain the system first?
