dno does the air con need to be removed but have never seen a fmic with air con so dno.. jackin a car can help greatly no matter what you are doing imo. the fmic is easy enough to install just go at it and its really easy to work out what you have to do.. basicly remove frnt bumper, drain rad take out rad should be held on with brackets two bolts on top disconnect two hoses top and bottom of the rad and disconnect the wire for fan can be a little akward to get out kept catchin in my bay, take tmic off and all pipes brackets clips etc, then ( i was lookin for a thread but couldnt find any with pictures so got this little bit of a different thread) got from a post by

its fairly easy mate.. first line out the cooler and piping on the ground 2 get your bearings.. in otherwards, pipe lay out as it would be fitted 2 the car, which hoses and clips go where on the piping.. then i suggest you mount the cooler first.. theres bolt holes undereneath the cross member.. use which ever for the support brackets for the cooler.. bend brackets and drill new holes if needs be..secure also 2 the bonnet latch support from top of cooler.. when the cooler is fitted run the pipe work/hoses/clips 2 where it suuposed 2 go and fiddle about with it all untill its in a good position and tighten up.. some cutting 2 the bumper and plastic gards may be needed depending on what fmic you got.. make sure you tighten up all fittings cause there is loads and can be overlooked.. trust me ive seen it happen loads of times before..
think that should cover it for ya. the put back on rad and reconnect fan brackets and put coolent back in i forgot in a corsa before puzzled how i forgot, make sure the air bubbles all come up when engine running warm.
