Where is the coolant fill cap on a Lincoln 2002 ls?

On a 2002 Lincoln LS :

The engine coolant reservoir is in the engine compartment , on the drivers

side of the engine compartment , next to the firewall . According to a drawing I

was looking at there is some kind of trim piece over the top of it , but the trim

piece has a hole in it to gain access to the engine coolant reservoir cap
