changing water pump

[twitchy]

Hey all

I wanted to confirm a few things i found when searching. I recall that changing the water pump on the KA engine isnt too hard a thing to do. I wanted to get some clairification on the matter before I get started tomorrow however

1) Where is the radiator drain plug?

2) When I unbolt the clutch unit on the fan to get at the water pump, what happens when I loosen the bolts? will the whole piece slide off seperate from the fan or is there something else I need to do? (Think of how the clutch looks...) Once the bolts are loose I mean...will it just come right off or is the fan attached to it as well by some other means?

3) How do I loosen the belt that drives the water pump, or do I need to? From what I gather, it looks like the power steering pump itself acts as the tensioner, with a bolt facing upwards and to the outer driver side of the engine, correct? (is it just the one bolt or?)

4) If you were me...would you change the thermostat as well "while your at it" or wait till it needed changing?

Thanks in advance!
