Does 08 hybrid have a block coolant drain plug? I know the radiator does. The factory shop manual says to make sure coolant drain plugs if equipped are tight????

 

Really doesn't matter as you would have had a problem by now.

 

I need to know where it is so can drain the old coolant & put in new.

 

The block drain plug on the Hybrid isn't even mentioned in the '09 Ford Workshop Manual probably because they use a Radiator Refiller Tool. You must bleed the air from the system also and it just mentions that being needed but no other info. I know the Owner's Manual gives the location of the bleeder valve. You add coolant till it comes out from at the valve while open.
