I seen that flex-a-lite had a fan for our trucks out now. I emailed them for more info and received none. Their site is difficult to navigate but they did send me to the right spot. The part number is 31163 it has its own temp sensor. it draws 28-36 amps. It says its for trucks w/o an electric clutch. It also says not to tow over 18,000 lbs GCW. I think that eliminates almost everyone. Maybe they are just covering their backside by the tow rating. Aren't all the fans equipped with an electric clutch. I have no idea on pricing. I am trying to find a solution to the poor stock clutch problem. It doesn't look like this is the answer.
