FYI, you dont have to remove that coolant hose from the front of the engine. A small wrench fits in there just fine. I also removed the fan as it made alot more room and takes about 1 minute to pull out. The fan comes out with one screw on the left side, unplug and lift up. Super easy and much easier access.
Couldn't hurt to change that oring anyway, but without the fan in the way I'm sure its much easier.
