The 2017 Ford Expedition typically features the 3.5L EcoBoost V6 engine, a powerhouse known for its blend of performance and fuel efficiency. This twin-turbocharged direct-injection engine requires specific attention, particularly concerning its turbochargers and fuel system.
Regular oil changes with the manufacturer-recommended synthetic oil are non-negotiable. Using the correct viscosity and type protects the turbo bearings and maintains optimal engine lubrication. Don’t overlook the importance of the air filter; a clean one ensures proper airflow to the turbos, preventing strain and maximizing power.
Transmission Care for Longevity
Most 2017 models are equipped with a 6-speed automatic transmission. This robust unit benefits immensely from timely fluid and filter changes. While some manufacturers claim “lifetime” fluid, experienced technicians recommend servicing around 60,000 to 100,000 miles, especially if you tow frequently.
Pay attention to any harsh shifts or delays in engagement. These could be early warning signs of transmission issues. Catching them early can prevent costly repairs down the road.
Routine Maintenance: The Foundation of Reliability
Proactive maintenance is the best way to ensure your Expedition remains dependable. Following a consistent schedule prevents small issues from escalating into major problems.
Oil Changes and Fluid Checks
Engine oil is the lifeblood of your EcoBoost engine. Check your owner’s manual for the exact synthetic oil specification and filter type. Typically, intervals range from 5,000 to 7,500 miles, but severe driving conditions (towing, extreme temperatures) may warrant earlier changes.
Beyond engine oil, regularly inspect your coolant level and condition. A healthy cooling system is critical for turbo longevity. Brake fluid, power steering fluid (if applicable), and differential fluids also require periodic checks and changes. Don’t forget your windshield washer fluid, especially before long trips.
Tire Health and Suspension Inspection
Tires are your Expedition’s only contact with the road, making their condition paramount for safety and performance. Rotate your tires every 5,000 to 7,500 miles to promote even wear. Check tire pressure weekly; the correct PSI is usually found on a sticker inside the driver’s door jamb.
Examine the tire tread for uneven wear, which can indicate alignment issues or worn suspension components. While rotating tires, take the opportunity to visually inspect suspension parts like shocks, struts, and control arm bushings for leaks or excessive play. Worn suspension components compromise handling and ride comfort.
Brake System Essentials
The braking system is critical for safety. Listen for squealing or grinding noises, which indicate worn brake pads. Visually inspect your brake pads and rotors during tire rotations. Rotors should be smooth, without deep grooves or warping.
If you’re a DIYer, replacing pads and rotors on a 2017 Ford Expedition is a manageable task, but always use a reputable brand of parts. Ensure you properly bleed the brake lines if you open the system. If you’re unsure, a certified mechanic can perform a thorough brake inspection and service.
Common Issues and Troubleshooting for Your Expedition
Even well-maintained vehicles can encounter problems. Knowing what to look for can save you time and money.
Diagnosing Check Engine Lights
A “Check Engine” light can signify a myriad of issues, from a loose gas cap to a serious engine problem. The first step is to retrieve the diagnostic trouble codes (DTCs) using an OBD-II scanner. Many auto parts stores offer this service for free, or you can purchase an affordable scanner for your toolbox.
Common codes for the EcoBoost engine might relate to misfires, oxygen sensor failures, or turbo system issues. Always research the specific code to understand its implications before attempting repairs. Sometimes, a simple fix like replacing a spark plug or ignition coil can resolve a misfire code.
Addressing HVAC and Electrical Glitches
The Expedition’s climate control system is generally robust, but issues like weak airflow or inconsistent temperature can arise. Check the cabin air filter first; a clogged filter severely restricts airflow. Electrical glitches, such as malfunctioning power windows or infotainment issues, often trace back to blown fuses. Consult your owner’s manual for fuse box locations and diagrams.
If you encounter persistent electrical problems, especially those affecting multiple systems, it’s wise to consult a professional. Modern vehicle electrical systems are complex and require specialized diagnostic tools.
Dealing with Suspension Noises
Clunks, squeaks, or groans from the suspension can be unnerving. These often point to worn bushings, ball joints, or sway bar links. A common culprit on higher mileage vehicles is worn shock absorbers or struts. While diagnosing, have a helper bounce the vehicle while you listen carefully to pinpoint the source of the noise.
Replacing these components requires proper jack stands, a good set of wrenches, and sometimes specialized tools like a spring compressor. Always prioritize safety when working under the vehicle. If you’re tackling suspension work, consider upgrading to heavy-duty parts if you frequently carry heavy loads or venture off-road.
Performance Modifications and Off-Road Setup
For those looking to enhance their 2017 Ford Expedition beyond factory specifications, several modifications can improve performance, utility, and off-road capability.
Engine Performance Upgrades
The 3.5L EcoBoost engine responds well to performance tuning. A reputable engine tune (ECU reflash) can significantly boost horsepower and torque by optimizing fuel delivery, ignition timing, and turbo boost pressure. Look for tunes from established companies that offer dyno-proven results and good customer support.
Other common upgrades include a cold air intake system for improved airflow and a performance exhaust system for better exhaust gas flow and a more aggressive sound. Always ensure any modifications comply with local emissions regulations.
Off-Road and Towing Enhancements
If your Expedition sees regular off-road action or heavy towing, consider upgrading its capabilities. A mild lift kit (2-3 inches) can provide crucial ground clearance for tackling rough terrain and allow for larger, more aggressive all-terrain tires. When choosing tires, balance off-road grip with on-road comfort and noise.
For towing, an aftermarket transmission cooler can help manage fluid temperatures, especially in hot climates or when hauling heavy loads. Upgrading brake pads to a heavy-duty compound can also improve stopping power. Consider a robust skid plate package to protect vital underbody components during off-road excursions.
Interior and Exterior Customizations
Beyond performance, many owners personalize their Expeditions with interior and exterior upgrades. LED lighting conversions offer brighter, more efficient illumination. Aftermarket infotainment systems can bring modern features like Apple CarPlay or Android Auto to older models.
Exterior accessories like roof racks, cargo carriers, and running boards add functionality and style. For off-roaders, a front bumper with a winch mount can be a critical recovery tool. Always ensure any modifications are compatible with your vehicle and installed safely.
Safety First: Essential Checks and Practices
Safety is paramount, whether you’re performing DIY maintenance or embarking on an adventure.
Pre-Trip Inspections
Before any long journey, especially one involving towing or off-roading, perform a thorough pre-trip inspection. Check all fluid levels, tire pressure (including the spare), and the condition of belts and hoses. Test all lights, turn signals, and horn.
Ensure your recovery gear (tow strap, shackles) is in good condition and easily accessible if you’re heading off-pavement. Always inform someone of your route and expected return time, especially when venturing into remote areas.
Working Safely on Your Vehicle
When performing any maintenance, prioritize safety. Always use sturdy jack stands on a level surface when lifting your vehicle; never rely solely on a jack. Wear appropriate personal protective equipment (PPE) like gloves and eye protection.
Disconnect the negative battery terminal before working on electrical components. Allow the engine and exhaust to cool down before handling hot parts. If a task feels beyond your skill level or requires specialized tools, don’t hesitate to call a licensed professional. Your safety and the integrity of your vehicle are worth it.
