Ok i know this is a dumb question but where is the coolant remote reservoir located on the car?

 

The fill cap for it is just behind the battery. It says "Engine Coolant Only" on the cap. I guess the reservior is under the battery.

 

The reservoir is under the battery.
Pull the battery and remove the battery tray.
You'll be able to get it out then. Its been a long time since I took one out so there may be other attachement points that I don't recall.
