Ford recalls nearly 200,000 Expeditions and Navigators for fire risk

Ford is recalling 2015-2017 Expeditions and 2015-2017 Lincoln Navigators because the front blower motor could fail and cause a fire. In total, 198,482 Expeditions and Navigators will be recalled. In the official recall documents posted by NHTSA, Ford says that it “has not identified the cause of this condition.” However, Ford also says it is currently aware of 25 fire allegations related to the blower motors on these vehicles. Despite not strictly identifying the cause of blower motor fires, Ford put forth a theory in its fieldwork analysis of the issue.  “In June 2022, based on component analysis, Ford Engineering theorized that a mispositioned blower motor brush holder spring could cause an internal short or localized heating of the brush spring or holder. It is believed that when a fire initiates on the blower motor, it does so at the positive brush holder location. The variable blower controller would remain operational and there would be no signs of an overheated relay. Field data indicates that this concern typically occurs at a higher time in service, and on vehicles with higher mileage.” Since the blower motor is located on the passenger side interior behind the glovebox, the fires that start are interior fires. Ford isnÂ’t aware of any accidents related to this issue, but there is one claim of burnt hands and fingers as a result of a fire. According to Ford, warning signs of an impending fire or failed blower motor include an inoperative fan, burning smell and/or smoke from the instrument panel vents while the vehicle is on. To remedy this situation, Ford is recalling the affected SUVs and replacing the blower motor assembly with a revised part. The new part uses a blower motor assembly design utilized on other applications. If folks with these SUVs experience any symptoms of blower motor failure before the new part becomes available, Ford says they can take their vehicle to the dealer to have it replaced with a part of the same design. Once the redesigned part becomes available, the dealer will then swap it in. Owner notification letters are expected to begin on September 12 this year.

Ford highlights new F-650 and F-750 with full-size Tonka show truck [w/videos]

Who among us hasn't been tempted by the prospect of buying a big yellow truck and painting the name Tonka along the side? Well apparently there were some folks over at Ford who were just as tempted, only they actually had the means to make that childhood fantasy a reality in the form of the truck you see here. Revealed at the NTEA Work Truck Show this week in Indianapolis, this Tonka show truck stands nearly 10 feet tall. It's painted bright yellow, just like the one you played with in the sand box (and probably still would given the opportunity and maybe no one else looking) and has a blacked-out nose treatment and special graphics. As you can see, it's also equipped with a working dump bed, and has a truly staggering 33,000-pound gross vehicle weight rating, built to showcase the Blue Oval's new line of medium duty trucks. Of course "medium duty" is a relative term, and the new F-750 is clearly a heavier piece of machinery than the company's own Super Duty pickups, but they're lighter-duty than a proper big rig. The new 2016 Ford F-650 and F-750 are just as tough as the models they replace, but they're now quieter and more comfortable to use. In fact, Ford says its 6.7-liter Power Stroke V8 diesel is now 25-percent quieter inside the cabin at highway speeds, 45-percent quieter at idle and 35-percent quieter standing outside in front of the grille. Ford notes that it's the only medium-duty truck manufacturer that makes its own engines and transmissions. That Power Stroke diesel comes with 270 horsepower and 675 pound-feet of torque as standard, but can be upgraded to 300 hp and 700 lb-ft or all the way up to 330 hp and 725 lb-ft. Commercial buyers will also be able to choose between Regular, Super and Crew Cab models with a straight-frame, dock-height or tractor-towing frames, meaning that whatever it is you've got to haul, chances are high that the new Ford F-650 and F-750 can be set up to get the job done.

A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.
