my radiator is getting replaced and I'm wondering if theirs anything else that should be done considering bumper, intercooler, radiator have to come off anyway for the install. Thanks

There's that short hose on the top-right (looking from the front) that the overflow line connects to. I'd replace that, along with replacing the overflow line with a metal version since it likes to break if you look at it funny.

For what it's worth, I replaced my radiator at 90k and nothing else. It's been fine for ~15k miles.
Be careful with the nipple on the upper radiator hose. It can snap off when removing the expansion tank hose. |

Along with rad, might as well change your rad hose coming from oil filter housing and overflow hose on top of rad.
While the rad is out you have clear access to belt and tensioner, so something to consider. No need to take the bumper off. |
