First off....you could have gotten the same fans from Summit Racing for 189 i believe.....PHR charges 250??? They are same fan setup. Also..not sure how you are going to do it..but i have mine setup up to run all the time....basically anytime the key is turned over. As for the fan shroud..pretty much straight forward. Will have to get under car though a little bit......just jack up front of car. Take off the big underpanel if you still have it to access the under side of fan shroud. I belive going by memory their are 2 10mm bolts up top ..and 2-3 down the bottom under car. There is a clip or to undo...And also remove or unhook one end and get out of way the upper radiator hose so you can pull fan shroud out. The fan shroud should easily pull out....and to remove the fan...Just remove the 4 10 mm nuts holding fan onto pulley.....then remove fan..and replace the nuts back on the pulley. Thats it....then just install the fans. 12v ign Power, ground, tie in the supplied 30 amp fuse. And thats it. Works awesome. No need to run off thermostat or anything like that. Just have them run all the time.
