Re: GT Fluid Leak - Front Grille
At the front of your car there is a power steering fluid cooler, but I'm not sure whether its at the passenger side or driver's side. On my car its on the driver's side, but on a 156/147 GTA it is on the passenger's side. This would explain your steering fluid being low.
The cooler is not a radiator, just a pipe that goes to the front of the car, coils around a few times (for surface area), then the pipe goes back the way it came, to the power steering pump I assume.
