Hey, thanks for the detailed info! Although, I figured the fill point was at the "clear" plastic tank in front of the car -- you know, the one with the hot/cold fill lines. It even has a long, flexible plastic dipstick.
If that's not the correct fill spot, then I guess I gotta learn a bit more. Where exactly is the other (correct) fill point? I'll go home and stare at my engine bay for a while tonight.
