My daughters 2013 Mii has overheated a few times recently. Inspection in the engine bay is horrendous but it feels like bearing in the cooling fan has failed. Aside from the fact that the local SEAT dealer wants an eye watering £350 +VAT just for the part. Changing the fan doesn't look that difficult if I can get the front bumper off - the problem is I can't see how it comes off and there's no maintenance manuals on the market. Anyone else got experience of bumper removal and/or changing the radiator on the Mii?
