1990 Tercel radiator fan

I've had this car for a year and a half now and only noticed yesterday that
the electric fan doesn't ever come on.  It's cool here year round, so the
temp gauge never goes up but I decided to have it fixed, anyway.  Took it to
the Toyota dealer and they said it needs a new fan.  $100 for the fan and
$200 labor.  I ordered the fan but when I got home, I took a look and it
doesn't look like more than 4 bolts and an electrical coupling to change out
the old one.
Has anyone dones this job that wants to give me a few tips.  I expect it to
be a knuckle buster on such an old car but $200 just seems like too much for
something that looks so easy.
Thanks,
Tom
