I want to change the coolant and only find two block plugs. Is this where it's at? Or what is the usual proceedure for draining and changing coolant in these cars?[/quote:e86f590011]

the radiator pep cock is on the drivers side of the radiator up on the side,

I would go and have it power flushed, it removes all coolant and some good additives are added
