*This is my second time doing this because the first time I ordered aftermarket lines to save money, ended up getting everything in and the upper line was .007" larger on the rad side then the one i pulled out. Needless to say it wouldnt fit so i had to take everything back apart and put the old upper line back in until fcp sent me oem ones. So i suggest you measure your old and new lines with calipers and possibly save some trouble. Also found large burrs on the engine side of the lines that could easily tear the small green o rings so check for that as well. Big thanks to fcp for fixing me up quickly!
First get the car on stands and remove the passenger side wheel. I then pulled the inner plastic fender well up and tied it off.
I then used the snap ring pliers to remove the upper and lower lines and let all the oil out that i could.
Upper line at rad

lower line at rad

I also removed the filter as i was changing my oil at the same time, it gave me more room to work with.
Under side view of leaky lines.

After that i removed the two torx 40's on the engine side and let the oil drain there.

After the oil had drained i removed the 10mm trouble maker bolt with a 1/4 flexible extension.

I took the thermostat off with the lines still attached so i could get to the torx 27 easier.
This is it after getting the clamp off.

After cleaning everything i greased the new green o rings that go on the engine side and put them in before putting the lines back in. Be careful as they are easily damaged.

There is only one way the tabs on the hoses will line up for the 10 mm bolt so its impossible to put the lines in the thermostat backwards.
After putting the lines back into the housing and clamping them i slid the whole assembly back up into place. I routed the lines where they were supposed to go and tied them to keep them from falling back down.
To keep the square o ring on the thermostat i used a lot of vaseline. Make sure to check that it has stayed in place before you fully tighten down the thermostat.
Next, and the hardest part for me, was getting the 10mm bolt back through the tabs on the lines and secured to the block. I held the lines up with my thumbs and started the bolt with my two index fingers. It was a real pain but it was the only method i could get to work for me. I read somewhere about stuffing the back of the socket with paper so it wont completely bite the bolt. If the bolt is all the way in the socket then its almost impossible to get it started straight. I couldnt get that method to work so i guess just do whatever will work for you.
Last, i plugged the lines into the radiator. Dont forget to put more oil back in for what you lost. Start it up and check for leaks, hopefully their wont be any and you can enjoy a job well done.
hope this helps!
