Ford updates Power Stroke diesel V8, strengthens F-450, tweaks King Ranch

Ford is giving its F-Series Super Duty trucks some upgrades for 2015, and we're happy to say that one of them is an improved Power Stroke diesel V8. Also, Ford is strengthening the top-of-the-line F-450 to handle more abuse. And if wild west-style luxury is your thing, the automaker has performed minor cosmetic updates to its King Ranch Edition trucks, as well.
The turbocharged 6.7-liter Power Stroke V8 is currently rated at 400 horsepower and 800 pound-feet of torque, and Ford only tells us the new and improved Power Stroke can "produce power beyond today's" engine. What, then, did Ford actually improve upon? First, the Blue Oval swapped in a new, larger turbocharger. The new Garrett GT37 turbine unit is 72.5 millimeters in diameter, eclipsing the old GT32's 64-mm diameter piece. Ford states output increases with the new turbo setup, but since the new turbocharger operates at a lower peak pressure than the old one, the automaker was able to eliminate the wastegate system and reduce the engine's complexity. Ford even redesigned the turbo's oil and cooling lines to make the powerplant simpler. A byproduct of the larger turbo is better engine exhaust braking, which is controlled manually by a button on the dashboard.
Ford claims the upgraded diesel engine is more powerful, more robust, more efficient and more refined than before.

Ford recalls 650,000 trucks and SUVs for defective wipers

Ford announced earlier this month that it is recalling 652,996 F-Series pickups, Expeditions and Lincoln Navigators produced for the 2020 and 2021 model years to address an issue that may cause their windshield wipers to separate, reducing visibility and leading to potentially hazardous driving conditions.  According to the Blue Oval, one of its suppliers used worn tooling components that resulted in wiper arms being produced with splines that are not tall enough to fully engage the motor pivots they're mounted to, which can cause the connection to strip when the motors are turned on. This could result in the wiper arms not moving at all, or engaging only intermittently.  "Worn wiper arm spline tooling core inserts at the supplier resulted in insufficient spline tooth height, which can cause the arm attachment to strip when used with a certain wiper motors with higher torque," Ford said in its defect report to NHTSA. "Potential symptoms include erratic or slow wipe speed of the driver or passenger wiper arm. An improper functioning wiper arm may potentially result in reduced visibility in certain conditions, which could increase the risk of a crash." Ford says the vehicles were not produced in VIN order, so while not all of the nearly 653,000 vehicles have bad wiper arms, they're all suspect until proven safe. Ford will notify owners of the recall campaign starting in May.  Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
