Sorry about your brother.
Remove the fan belt by using the spanner wrench to hold the pulley still while loosening the nut. There is a half-moon "key" in the shaft, so don't let that fall down under the bottom pulley.

Unbolt the strap and pull the fan housing toward you. This will allow you to access the fasteners on the back, which hold the plastic air cone thingie and the alternator. I believe they are 10mm nuts. Patience.

Then, the cool trick for getting the alternator to fall out of the fan housing is to set up a pile of rags on the floor, and set a 2x4 or two next to the rags. Bang the fan housing, upside down, on the 2x4, gently, a little at a time, moving around the housing with each tap, until the alternator falls out onto the rags.
