Let’s dive into the mechanical heart of this beast and ensure your investment stays on the road for another decade. Our goal is to empower you with the knowledge to handle most tasks in your own garage.
Understanding the Power: The 3.5L EcoBoost V6
The heart of the 2017 ford expedition el king ranch is the 3.5-liter EcoBoost V6 engine. This engine produces 365 horsepower and a massive 420 lb-ft of torque. It relies on two small turbochargers to provide low-end grunt, which is essential for moving such a heavy vehicle.
Maintenance on an EcoBoost engine is slightly more demanding than a naturally aspirated V8. You must prioritize high-quality filtration and frequent fluid changes to protect the turbo bearings. Heat is the primary enemy of these components, especially during heavy towing sessions in the summer.
Oil Change Best Practices
Always use a full synthetic 5W-30 motor oil that meets Ford’s WSS-M2C946-A specification. Synthetic oil resists thermal breakdown better than conventional blends, which is critical for the turbocharger cooling lines. Change your oil every 5,000 miles rather than following the optimistic 10,000-mile “Intelligent Oil-Life Monitor.”
Pair your oil with a Motorcraft FL-500S filter. This filter features a silicone anti-drainback valve that prevents dry starts. Dry starts are a leading cause of premature wear on the timing chain and cam phasers. A few extra dollars on a quality filter saves thousands in engine repairs later.
Spark Plug Maintenance and Gapping
EcoBoost engines are notorious for being “hard” on spark plugs due to high cylinder pressures. If you feel a slight shudder under acceleration, it is likely a fouled plug or a cracked ceramic insulator. Inspect your plugs every 30,000 miles to ensure optimal fuel economy and smooth idling.
When replacing them, use Motorcraft SP-534 (or the updated SP-580) iridium plugs. Ensure the gap is set strictly between 0.028 and 0.030 inches. A wider gap can cause the spark to “blow out” under high boost levels, leading to a frustrating misfire that triggers a Check Engine Light.
Maximizing the 2017 ford expedition el king ranch Utility and Towing
The “EL” in the name stands for Extended Length, adding nearly 15 inches to the overall wheelbase. This extra room translates into a cavernous 130.8 cubic feet of maximum cargo space. However, the added weight means you must be diligent about your suspension and braking systems when loaded.
This trim level often comes equipped with the Heavy-Duty Trailer Tow Package. This includes a Class IV hitch, a 4-pin and 7-pin connector, and an integrated trailer brake controller. Understanding how to use these tools properly will keep you safe on steep mountain descents.
Managing the Load
Check your tire pressure before every long trip. The 2017 ford expedition el king ranch typically runs on 20-inch or 22-inch wheels. Ensure your tires are rated for the “Extra Load” (XL) capacity to handle the tongue weight of a heavy trailer without sidewall failure.
If your vehicle sags significantly when hitched, consider a weight-distribution hitch. This hardware transfers weight from the rear axle to the front wheels. This improves steering response and prevents the “light” front-end feeling that causes many highway accidents.
Brake System Upgrades
Stopping a 6,000-pound SUV plus a trailer requires immense friction. If you frequently tow, upgrade to carbon-fiber ceramic brake pads. These pads offer better thermal stability and less brake fade than the standard organic pads found at most local auto parts stores.
Flush your brake fluid every two years. Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. Moisture lowers the boiling point of the fluid, which can lead to a “spongy” pedal during heavy braking. Use a high-quality DOT 4 fluid for better heat resistance.
Interior Preservation: Caring for Mesa Brown Leather
The defining feature of the King Ranch is the Mesa Brown leather interior. Unlike the treated, plastic-coated leather in most cars, this is a more “natural” hide. It feels incredibly soft and smells like a premium saddle shop, but it is prone to drying out and cracking if neglected.
Direct sunlight is the biggest threat to your dashboard and seats. Use a high-quality ceramic window tint to block UV rays. This simple step prevents the rich brown dye from fading into a chalky orange color over time.
Cleaning and Conditioning Steps
Avoid “all-in-one” cleaners that contain harsh solvents or silicones. These products can clog the pores of the leather and create a greasy sheen. Instead, use a dedicated leather cleaner and a soft horsehair brush to gently lift dirt from the grain.
Apply a lanolin-based conditioner specifically designed for King Ranch leather. Apply the conditioner with a microfiber applicator and let it sit for several hours. Wipe away any excess with a clean cloth to restore the supple feel and deep color of the hides.
Electronic Maintenance
The 2017 model year features the SYNC 3 infotainment system, which is a massive upgrade over previous versions. Keep your software updated via Wi-Fi to ensure compatibility with Apple CarPlay and Android Auto. If the screen freezes, perform a “soft reset” by holding the Power and Seek Up buttons simultaneously.
Check the USB ports in the center console for debris. Dust and lint can prevent a solid connection, leading to dropped phone signals. A quick blast of compressed air usually solves connectivity issues without needing to replace the entire module.
Common Problems and DIY Troubleshooting
Every vehicle has its quirks, and the 2017 ford expedition el king ranch is no exception. Being a “careful DIYer” means identifying sounds and vibrations before they turn into expensive roadside breakdowns. Most of these issues can be diagnosed with a basic OBDII scanner and some patience.
One common complaint is a rattling noise from the engine during a cold start. This often points to the cam phasers or the timing chain tensioners. If the rattle lasts more than two seconds, consult a professional, as a skipped timing chain can destroy the entire engine.
The IWE 4WD System
If you hear a “grinding” noise from the front wheels while in 2WD, your Integrated Wheel Ends (IWE) may be failing. This system uses vacuum pressure to disengage the front hubs. A small crack in a vacuum line or a faulty check valve will cause the hubs to partially engage, creating a metal-on-metal sound.
You can test this by switching to 4H (4WD High) while driving. If the noise disappears, the problem is definitely in the vacuum circuit. Replacing the IWE check valve is a 5-minute DIY job that costs less than twenty dollars and prevents damage to the hub splines.
CCD Suspension Issues
Many King Ranch models feature Continuously Controlled Damping (CCD). This system uses sensors to adjust the shock absorbers in real-time. If you notice an unusually bouncy ride or see a “Suspension Fault” message, inspect the wiring harnesses near the wheel wells.
Road debris or salt can corrode the electrical connectors for the shocks. Clean the connectors with electrical contact cleaner and apply a dab of dielectric grease. If a shock is leaking fluid, it must be replaced; however, these electronic shocks are significantly more expensive than standard ones.
Off-Roading and Performance Modifications
While the 2017 ford expedition el king ranch is built for luxury, its truck-based frame makes it a capable off-roader. The EL wheelbase can be a challenge on tight trails, but it excels in open desert or sandy beach environments. A few strategic mods can turn this family hauler into a weekend adventurer.
The first upgrade should always be tires. The stock highway-terrain tires are designed for quietness, not grip. Swap them for a set of All-Terrain (A/T) tires with a 3-peak mountain snowflake rating. This provides better traction in mud, snow, and loose gravel.
Leveling Kits and Ground Clearance
The front end of the Expedition sits lower than the rear to improve aerodynamics. This “rake” can cause the front air dam to scrape on trail obstacles. A 2-inch front leveling kit is an affordable way to increase ground clearance and allow for slightly larger tires.
Installing a leveling kit requires a spring compressor and a torque wrench. If you are uncomfortable working with compressed springs, have a local shop perform the install. Always get a professional wheel alignment immediately after changing any suspension components to prevent uneven tire wear.
Engine Tuning for Towing
If you find yourself frequently hauling heavy loads, an aftermarket engine tune can unlock hidden potential. Tuners like 5-Star or Cobb can recalibrate the ECU to optimize the shift points of the transmission. This keeps the engine in its “power band” longer, making hill climbs much smoother.
Be aware that tuning can affect your powertrain warranty if you still have one. Always use the highest octane fuel available (91 or 93) when running a performance tune. This prevents “knock” or “pre-ignition,” which can be catastrophic under high boost conditions.
Safety First: Essential Checks Before the Trail
Safety is paramount when operating a vehicle as large as the 2017 ford expedition el king ranch. Before heading off-road or on a long road trip, perform a “nut and bolt” check of the undercarriage. Ensure the skid plates are secure and that there are no leaks from the transfer case or differentials.
Carry a recovery kit that includes a snatch strap, D-rings, and a portable air compressor. Because of the vehicle’s weight, never use a standard “tow rope” with metal hooks for recovery. These can snap and become deadly projectiles. Only use kinetic energy straps designed for heavy vehicles.
- Check the Spare: Ensure your spare tire is inflated and that the winch mechanism to lower it isn’t rusted shut.
- Fluid Levels: Verify coolant, transmission fluid, and power steering levels.
- Lighting: Test all exterior lights, including the trailer plug circuits.
- Emergency Kit: Keep a first-aid kit, jumper cables, and a basic toolset in the rear cargo area.
Frequently Asked Questions About 2017 ford expedition el king ranch
What is the difference between the EL and the standard Expedition?
The EL (Extended Length) model is roughly 15 inches longer than the standard version. This length is added behind the rear wheels, providing significantly more cargo space behind the third row. It also features a larger 33.5-gallon fuel tank compared to the standard 28-gallon tank.
Does the 2017 model have the transmission issues of earlier years?
The 2017 model uses the 6R80 six-speed automatic transmission, which is widely considered one of Ford’s most reliable units. It is much more robust than the 10-speed transmissions found in later years. Regular fluid exchanges every 60,000 miles will keep it shifting smoothly for a long time.
Can I fit 35-inch tires on a King Ranch?
Fitting 35-inch tires usually requires a minimum 3-inch lift and some trimming of the inner fender liners. For most owners, a 33-inch tire on a 2-inch leveling kit is the “sweet spot” for maintaining ride quality while improving off-road capability.
Is the Mesa Brown leather hard to maintain?
It requires more frequent conditioning than standard black leather. Because it is a more natural hide, it can absorb body oils and dirt more easily. However, with quarterly cleaning and conditioning, it develops a beautiful “patina” that looks better with age.
