We bought our truck in Feb 2014 and noticed this behavior last year and now it's back. It seems that when it's really hot out and we're running the A/C, the engine fans or something kicks in and sounds like a jet engine it's so loud. It didn't do that over the winter, and our winter was fairly mild. Yesterday was our first 100+ degree day and the jet engine was back. Even after stopping for a bit at a store and going again, the noise just started back up. It's incredibly annoying both in and out of the cab. Is this normal for the EcoBoost in hot locations like the California central valley? If so, is there anything we can do to help alleviate it (like a K&N air filter or different chip)?
