Critical Maintenance for the 2014 ford explorer sport awd
The most important aspect of owning this vehicle is staying ahead of the maintenance curve, particularly regarding the drivetrain. Unlike the base models, the Sport trim puts significantly more stress on its mechanical components due to the increased horsepower and torque. Neglecting small issues can lead to catastrophic failures in the all-wheel-drive system.
One of the most discussed components in the enthusiast community is the Power Transfer Unit (PTU). This gearbox sends power to the rear wheels, but it sits very close to the exhaust manifold, leading to extreme heat soak. Over time, the factory fluid can break down into a thick, sludge-like consistency that destroys the internal bearings.
To protect your 2014 ford explorer sport awd, I recommend changing the PTU fluid every 20,000 to 30,000 miles. Ford originally claimed this was a “lifetime” fluid, but experienced mechanics know better. Use a high-quality 75W-140 synthetic gear oil to ensure the gears remain lubricated even under high-temperature conditions.
The Water Pump Challenge
The 3.5L EcoBoost engine uses an internal water pump driven by the timing chain. This design choice means that if the pump’s internal seal fails, coolant can leak directly into the oil pan. This creates a “milkshake” mixture that can ruin your engine bearings in a matter of minutes.
Check your oil dipstick weekly for any signs of a milky or frothy appearance. Also, monitor the “weep hole” located behind the alternator on the side of the engine block. If you see orange or green crusty residue there, your water pump is failing and needs immediate professional attention.
Carbon Buildup on Intake Valves
Because the 2014 ford explorer sport awd uses direct injection, fuel never washes over the back of the intake valves. This allows carbon deposits to bake onto the valves, eventually causing rough idles and loss of power. Using a dedicated intake valve cleaner every 10,000 miles can help mitigate this common issue.
Understanding the Intelligent All-Wheel Drive System
The AWD system in this vehicle is “intelligent,” meaning it constantly monitors wheel speed, throttle position, and steering angle. It can shift torque between the front and rear axles in milliseconds to prevent wheel slip. This makes the 2014 ford explorer sport awd an excellent choice for rainy or snowy climates.
The system is controlled by the Terrain Management System (TMS) knob located on the center console. This knob allows you to choose between Normal, Mud/Ruts, Sand, and Grass/Gravel/Snow modes. Each mode changes the throttle mapping, transmission shift points, and the aggressiveness of the center coupling.
When you drive the 2014 ford explorer sport awd in “Sand” mode, the system stays in lower gears longer and prevents the traction control from cutting engine power. This allows you to maintain the momentum needed to stay on top of soft surfaces. Always remember to switch back to “Normal” once you reach pavement to save fuel.
Hill Descent Control
Your Sport trim likely comes equipped with Hill Descent Control, which acts like an off-road cruise control for steep declines. When activated, the vehicle uses the ABS system to pulse the brakes on individual wheels. This keeps you at a steady, slow speed without you having to touch the brake pedal.
Tire Pressure and AWD Health
AWD systems are extremely sensitive to differences in tire diameter. If one tire is significantly more worn than the others, it can trick the wheel speed sensors into thinking a slip is occurring. This puts unnecessary wear on the center clutch pack and can cause a “binding” sensation during tight turns.
Always replace tires in sets of four on your 2014 ford explorer sport awd. If you must replace just one, ensure it is the exact same make and model as the others. Keeping your tires rotated every 5,000 miles will help ensure even wear and protect your expensive drivetrain components.
Performance Upgrades for the 3.5L EcoBoost
The Sport trim is already fast, but the 3.5L EcoBoost engine has massive potential for aftermarket gains. Many owners find that a few simple modifications can unlock an extra 50 to 100 horsepower. However, you must ensure your maintenance is up to date before adding more boost.
A high-quality engine tune is the most effective way to increase performance. A tuner can adjust the wastegate duty cycles and ignition timing to sharpen throttle response. This makes the heavy SUV feel much lighter on its feet and improves highway passing power significantly.
Upgrading the 2014 ford explorer sport awd suspension is another popular route for enthusiasts. The stock struts are tuned for a balance of comfort and sport, but they can feel a bit “floaty” at high speeds. Installing lowering springs or heavy-duty sway bars can drastically reduce body roll in corners.
Cold Air Intakes and Intercoolers
The factory intercooler is known to “heat soak” after a few hard pulls, meaning it can no longer effectively cool the compressed air from the turbos. An upgraded front-mount intercooler (FMIC) provides more consistent power. This is especially useful if you live in a hot climate or enjoy spirited driving.
While a cold air intake provides a nice “whoosh” sound from the blow-off valves, the performance gains are usually minimal without a tune. Focus on high-flow dry filters if you want better airflow without the risk of oil fouling your Mass Air Flow (MAF) sensor. Clean air is vital for turbo longevity.
Exhaust System Enhancements
The stock exhaust is quite muted, hiding the growl of the V6 engine. A cat-back exhaust system can provide a deeper tone without creating excessive “drone” inside the cabin. Look for systems specifically designed for the Sport trim to ensure the tips align perfectly with the rear bumper cutouts.
Common Suspension and Chassis Issues
The 2014 ford explorer sport awd is a heavy vehicle, weighing nearly 5,000 pounds. This weight puts a tremendous amount of load on the front control arms and rear toe links. It is common to hear “clunking” or “popping” noises when driving over speed bumps or turning the wheel.
One major area of concern is the rear toe link. Ford has issued several recalls for this component because it can snap under stress, leading to a loss of steering control. Check your VIN on the NHTSA website to ensure your vehicle has the updated, reinforced parts installed.
If you experience a vibration in the steering wheel at highway speeds, it may not just be a tire balance issue. The front strut mounts on the 2014 model year are known to wear out prematurely. Replacing them with heavy-duty aftermarket units can restore that “new car” steering feel and precision.
Brake System Upgrades
Stopping a heavy, turbocharged SUV requires significant braking force. If you notice your brakes “fading” or feeling spongy during mountain descents, consider upgrading to ceramic brake pads. These pads handle heat better than the standard organic versions and produce much less dust on your wheels.
Wheel Bearing Maintenance
Listen for a low-frequency “humming” or “growling” noise that changes pitch with vehicle speed. This is the classic sign of a failing wheel hub assembly. Because the Sport has AWD, the front bearings are under constant load. Replacing them early prevents damage to the CV axles and ABS sensors.
DIY Troubleshooting and Diagnostic Tools
To properly maintain your 2014 ford explorer sport awd, you should invest in a basic OBD-II scan tool. This allows you to read Diagnostic Trouble Codes (DTCs) when a Check Engine Light appears. Knowing the code before going to a mechanic can save you hundreds of dollars in diagnostic fees.
For more advanced DIYers, a software called FORScan is a game-changer. It allows you to access dealer-level modules and perform tasks like battery relearns or disabling the “double honk” feature. It also lets you monitor live data from the PTU and transmission sensors in real-time.
When troubleshooting an engine misfire, always start with the spark plugs. The EcoBoost engine is very sensitive to spark plug gap. Over time, the high boost levels can “blow out” the spark if the gap is too wide. I recommend checking and re-gapping your plugs every 20,000 miles to 0.030 inches.
Checking for Boost Leaks
If your Explorer feels sluggish, you might have a boost leak. Check the rubber hoses connected to the intercooler and turbo inlets. These can crack or become loose over time. A simple spray of soapy water while the engine is running (carefully) can help identify escaping air bubbles.
Battery and Charging System
Modern Fords are very sensitive to voltage drops. A weak battery can cause “phantom” electrical issues, such as random warning lights or radio glitches. If your battery is more than four years old, replace it with a high-CCA (Cold Cranking Amps) unit to ensure the electronics stay happy.
Frequently Asked Questions About 2014 ford explorer sport awd
Is the 2014 Ford Explorer Sport AWD good in the snow?
Yes, it is excellent in the snow thanks to the Grass/Gravel/Snow setting on the Terrain Management System. This mode softens throttle response and uses the AWD system to provide maximum traction. For the best results, pair the AWD system with a dedicated set of winter tires.
What is the towing capacity of the 2014 Sport trim?
When properly equipped with the factory Class III towing package, the 2014 Ford Explorer Sport AWD can tow up to 5,000 pounds. This is enough for a small boat, a utility trailer, or a lightweight camper. Always use a weight-distribution hitch for better stability when towing near the limit.
Does the 2014 Explorer Sport require premium fuel?
While the engine can run on 87 octane, Ford recommends 91 or 93 octane for maximum performance. Using premium fuel allows the computer to run more aggressive timing, which results in better horsepower and slightly improved fuel economy.
