Although the fan in my 2014 GT was still working (60K miles), now that the car lives in Florida, and I frequently track the car at Test & Tune events, I decided to preemptively replace the stock unit with the Ford Performance GT500 unit. I also purchased the modified resister pack from wireeverything.com (thanks to those who posted this link), which is a high quality, professional solution. These units are not mass produced, so there could be some lead time. In my case, I placed the order on January 21, 2024, and received the part on February 24. If you plan on doing both the fan and the upgraded resister pack, I suggest that you order the resister pack first and then order the fan after the resister pack ships. The fan only took four days from Summit Racing. Swapping out the resister pack is much easier before the fan is in the car. As far as the fan installation goes, there are a few things to be aware of. The stock unit has a mounting point to secure the transmission lines if your car is an automatic. The GT500 unit does not have that, so you need to secure that bracket via zip ties, or some other means. Most videos make this look like a 30-minute job, but it took me a leisurely 3 hours, gradually disconnecting more things in order to get the old unit out without forcing things. After first disconnecting the negative battery terminal, I removed the strut tower brace and engine cover. Next the plastic panel covering the area between the upper grill and the radiator came off. Once the bolts are removed, the coolant reservoir does just lay back out of the way. Removing the top hose on the radiator makes it much easier to remove and replace the fan, you may want to do this just before you try to lift out the old fan. It didn't leak much, but you still should have a pan under the car and a rag to stuff in the radiator outlet. I broke the factory hose clamp (using the wrong tool to release it) and had to run out to the auto parts store for a replacement. The driver's side mounting stud was a little bit of a challenge due to the cold air snorkel. I have a Steeda CAI that I completely removed, but I'm not sure if that's necessary with the stock airbox. I disconnected the wiring harness from the fan before removing the mounting bolts. Once you have the top two bolts out and the passenger side lower transmission line bracket bolt removed, the old fan should come out. Installation is pretty much the reverse. Of course, everyone's experience is usually somewhat different. Once I have some miles on the new fan, I will post up my impression of what measurable effect it may have. Sorry for the novel...
