One in the engine block, one in the bottom of the manifold and one in the exhaust elbow. I would also pull the big hose off the water pump/thermostat housing and tip the water out of there too... Poke the holes with a length of wire to clear the crap out....

but it doesnt show there locations?

Now there's a surprise! Try this for a real manual:- http://www.4shared.com/document/hh5Z9V47/Service_Manual_10.html
Page 5 in Section 6A is all about draining the engine for winter...
