Section 1
Park your car in a flat, level area and allow it to cool down properly.
Using a 10mm wrench, remove the negative terminal of the battery.
As long as things are cooled down and the radiator hoses easily squeeze and don't feel as though there's pressure you should be okay to start.
Pull the hose gently out of the coolant overflow tank, most of the fluid should drain back into the tank. If not lift the end of the hose upward to get it to drain back into the radiator.
On the side of the overflow tank that is towards the headlight (not the radiator) you'll notice the end of the tank is underneath a small tab. press this in to release the coolant tank and rotate it counter clockwise to free it from the fan shroud. you can then lift up and remove it from the car.
You'll want to set this somewhere safe and upright so the coolant inside doesn't spill. Don't get rid of it as we'll use it later.
Using a phillips screwdriver undo the clip for the washer fluid fill spout. In some cases if the center just spins in place without backing out you'll need to use a trim tool or screwdriver to gently lift the center of the tab out.
Grab the fill tube and gently lift upward. It should release from the lower half of the tank.
