The radiator and fan works great, I had some issues with my first fan relay controller (homemade), melted a relay, and went through two mechanical fan controllers. I was only using the high speed on the taurus fan.
I eventually came up with a redesigned fan controller (also homemade) with adjustable two speed control. Since it has been taking advantage of the low speed (set at 180), it hasn't needed to kick into high (set at 200) in hot weather with the AC on, the temp gauge reads about 190.
I think the battery could have stayed up front with a simple 90 degree remount of the battery tray.
To drain the radiator, I pull the bottom hose off. No big deal.
If you have decent fabrication skills and tools, I would recommend this mod. You might want to get an aftermarket fan control that brings the fan up to speed gradually, because the initial turn on can be hard on your electrical system if it's not up to it. Mine has a lot of modifications.
