I used to live there haha, but that was 10 years ago. I know, doesn't help.

What parts are you changing exactly? I did the thermostat, upper/lower hoses and expansion tank and it was pretty easy and straight forward.

Don't forget the rubber o-ring if you're replacing the lower hose otherwise it will squirt fluid out b/c the old ring is likely flattened and won't seal anymore.
I'm talking about the rubber ring that goes on the sensor pictured here
