John, Yeah you need to yank that blue plug ASAP. That thing is a sure fire way to ensure that your engine overheats. Get the Zilla or the Fan Fix Dual 2x2 by SpecialTauto.com. I personally opted for the latter and have not been disappointed, of course nor have my friends with FanZilla, but I payed a lot less. Get the overheat protector from DMCJoe, it is a lifesaver. That should set you straight, but make sure you get that @#$^%ed blue relay out and replaced by something STAT.
