Question Where is the second engine block coolant drain plug on a '97?

[ichbinroot]

Hi all,

I picked up used '97 Avalon last year and figured I'd change the coolant since I've got no clue when the last time it was done. The Haynes repair manual says that the V6 "has a coolant drain on both sides of the block". The one in the front is obvious, but for the life of me, I can't find the second. And I'm feeling like a major idiot cause I can't find the thermostat either. Anyone know where either of these are located? (This is the 1MZ-FE V6).

Thanks!
