Engineered specifically for 2020 through 2026 Ford F-250, F-350, F-450, and F-550 Super Duty trucks powered by the 6.7L Powerstroke V8 turbo diesel engine, the Genuine Ford Engine Fuse Box Cowl Water Deflector (Part # ML3Z-63022A68-A) serves as a critical protective barrier against moisture intrusion. On Super Duty trucks, rainwater and melting snow flowing down the windshield can cascade over the cowl panel and drip directly onto the engine bay power distribution center (fuse box) and surrounding electronic control modules.

Over time, exposure to moisture infiltration causes terminal corrosion, green crusting inside fuse sockets, erratic electrical faults, and communication errors across the vehicle's CAN bus network. Part number ML3Z-63022A68-A represents Ford's updated factory cowl shield designed to divert runoff safely away from sensitive electrical components. Molded from durable, weather-resistant automotive polymer to withstand under-hood heat cycles and UV exposure, this genuine OE deflector snaps directly into factory cowl mounting locations with zero core charge.

Key Features & Benefits

• Genuine Ford OEM / Motorcraft Component: Manufactured to exact factory specifications for perfect contour alignment along the firewall and cowl boundary.
• Protects Engine Fuse Box: Channels rainwater, wash water, and environmental debris away from the primary power distribution center and wiring harnesses.
• Prevents Electrical Corrosion: Stops moisture from pooling around fuse terminals, relays, and connector plugs, eliminating intermittent electrical gremlins.
• Durable Weather-Resistant Polymer: Constructed from high-grade thermal plastic engineered to resist cracking, warping, and embrittlement from extreme under-hood temperatures.
• Direct Snap-In Installation: Utilizes factory mounting clips and alignment tabs for a secure, rattle-free fit requiring no modification.
• Zero Core Charge: Brand-new outright factory part requiring no core deposit or core return shipping.

• Installation Tip: Open the hood and remove any accumulated leaf debris or pine needles from the lower windshield cowl troughs. Unclip the aging or damaged deflector shield carefully. Inspect the fuse box cover gasket for proper seating. Snap the new ML3Z-63022A68-A deflector firmly into the factory firewall retention slots, ensuring a tight seal that directs water runoff cleanly away from electrical terminals.
