Engine fans

I was having fun this weekend when the backlight of my pod sort of stuttered. Then the water temp regularly indicated up to the 100 degree mark but everything else was fine. Upon further investigation at home, as suspected, only one of the fans was working. Looking at fans from the drivers seat, the one furthest left cuts in at an indicated 100 degrees. It did manage to bring the temp down a few degrees but I would like to get the other one working again. I will pop into Halford to get a couple of 30amp fuses later.

Hopefully it's the fuse, looking at the handbook, does anyone know which fuse for the engine fan needs to be replaced?

Also, I thought the second fan should cut in earlier than an indicated 100 degrees? Otherwise that is leaving things a bit too late. The first fan (the failed fan) usually cuts in at around 93 degrees. Thanks. The cooling is a bit of a worry for me as the car lives and works in London. I fitted a 2 stage cooling kit for my previous Chim which worked well (brought the fans in earlier with half speed fans from 70 degrees)…anyone know of any mods for the Tuscan?

Oh, and some geezer nicked all of my shiny TVR valve caps when parked in London this weekend, left nice greasy prints on my spiders too… nice… and some drunk chap stopped me in the middle of the road and just pointed at the car and then gave a rude sign…
