Yea that is what I have read but mine is stuck on there good. I initially tried to get it off by using a hammer also but I was turning it counter clockwise if you are looking at the engine. The shop tried to get it off both using the air hammer spinning it clockwise and counter clockwise and still no luck.
If you've had the engine up fairly high in the RPM band,the fan can be a real ***** to get loose. The fan as has been stated is left hand thread,so it'll consequently tighten itself on really good if you've ran the engine hard. The idea of the left hand thread is so if the fan ever does loosen up, (like that'll ever happen,lol),it'll self tighten. On my 14 the fan was a real bear to get loosened,cost me a case of beer to get a tech at the local dealership to whack the hell out of it with an air hammer,and we fought with it probably close to 1/2 an hour before we finally got it loose,both me and the tech did some cursing,lol. I swore if I was ever doing it again,i'd do it before I had the engine on the limiter a few times,as they get real tight after the engines been wound out a few times,lol
