The 2014 Ford Explorer Limited AWD is a sophisticated three-row SUV that balances family comfort with a highly capable Intelligent 4WD system. To keep this vehicle performing at its peak, owners must pay close attention to the Power Transfer Unit (PTU) and the unique requirements of the 3.5L Ti-VCT engine.
You probably chose the 2014 ford explorer limited awd because you needed a vehicle that could handle school runs during the week and snowy trailheads on the weekend. We all agree that while this SUV is incredibly comfortable and packed with tech, it has a few specific mechanical quirks that can catch an unsuspecting owner off guard.
In this guide, I promise to walk you through the essential maintenance steps and troubleshooting tips that will save you thousands in dealership labor. We will preview the most common failure points, such as the Power Transfer Unit and the internal water pump, so you can drive with total confidence.
Whether you are a seasoned DIYer or a new owner looking to understand your vehicle better, these insights come from years of turning wrenches on the Ford D4 platform. Let’s dive into what makes this specific model tick and how to keep it on the road for the long haul.
Understanding the 2014 ford explorer limited awd Drivetrain
The heart of the 2014 ford explorer limited awd is its Intelligent 4WD system, which differs significantly from traditional truck-based 4×4 systems. Instead of a manual transfer case, this vehicle uses an electromagnetic clutch in the rear differential and a PTU up front to distribute torque.
This setup allows the vehicle to monitor wheel speed, throttle position, and steering angle hundreds of times per second. It can preemptively send power to the rear wheels before you even feel a slip, making it an excellent choice for rainy or icy conditions.
However, because the system is always “active,” it places a constant load on the drivetrain fluids. Understanding that this is a front-wheel-drive-biased system is crucial for diagnosing tire wear patterns and handling characteristics during heavy acceleration.
The Terrain Management System
One of the standout features of the Limited trim is the Terrain Management dial located on the center console. This allows you to calibrate the engine, transmission, and braking systems for specific environments like Normal, Mud/Ruts, Sand, or Grass/Gravel/Snow.
When you switch to “Sand” mode, the computer holds gears longer and allows for more wheel spin to maintain momentum. Conversely, “Grass/Gravel/Snow” mode dulls the throttle response to prevent you from breaking traction on slick surfaces.
If you find that the dial isn’t changing the display on your instrument cluster, you might be dealing with a faulty harness or a communication error in the ABS module. Always check for debris around the wheel speed sensors if your terrain modes start acting up.
Critical Maintenance: The PTU Fluid Myth
If you look at the official service manual for the 2014 ford explorer limited awd, you might see that the Power Transfer Unit fluid is listed as “filled for life.” As an experienced technician, I am telling you right now: do not believe that for a second.
The PTU sits very close to the exhaust manifold, which subjects the small amount of 75W-140 gear oil inside to extreme heat. Over time, this oil turns into a thick, black sludge that looks like burnt molasses, leading to bearing failure and a very expensive replacement.
To prevent this, you should aim to change your PTU fluid every 30,000 to 50,000 miles. Since many 2014 models do not have a drain plug, you will need a fluid extraction pump to suck the old oil out through the fill hole before pumping in fresh synthetic gear lube.
Signs of PTU Failure
How do you know if your PTU is crying for help? The most common sign is a faint “propane” or “burning oil” smell coming from the front of the vehicle after a long highway drive. This happens when the fluid overheats and vents out of the top of the unit.
You might also notice a high-pitched whine that increases with vehicle speed, regardless of what gear the transmission is in. If you see a “puddle” of thick, silver-streaked oil under the passenger side of the engine bay, the seals have likely failed due to excessive internal pressure.
Catching these symptoms early can mean the difference between a $20 fluid change and a $2,000 unit replacement. Always inspect the PTU housing for leaks every time you perform a standard oil change.
Troubleshooting the 3.5L Ti-VCT Internal Water Pump
The 2014 ford explorer limited awd usually comes equipped with the 3.5L Cyclone V6 engine. While this engine is generally robust and powerful, it has one major design flaw: the water pump is driven by the timing chain inside the engine front cover.
When these pumps fail, they don’t just leak on your driveway; they often leak coolant directly into the oil pan. If this goes unnoticed, the “milkshake” mixture of coolant and oil will destroy your engine bearings in a matter of miles.
Check your oil dipstick weekly. If the oil looks cloudy or the level is “rising” without you adding oil, stop driving immediately. You should also look for coolant weeping from a small hole behind the alternator, which is the designed fail-safe for a leaking pump.
DIY Water Pump Inspection
To check the health of your cooling system, look at the degas bottle (the plastic coolant reservoir). The coolant should be a clear orange or yellow color, depending on what was used during the last service.
If you see dark streaks or a filmy residue in the reservoir, it could indicate that oil is mixing with the coolant. This is often the first sign that the internal seals of the water pump are beginning to degrade.
Replacing this pump is a massive job that involves removing the entire front timing cover and timing chains. If you aren’t comfortable with advanced engine timing, this is one of those moments where I recommend calling a certified master technician.
Suspension and Steering: Common Wear Points
Because the 2014 ford explorer limited awd is a heavy vehicle, it puts a lot of stress on its front-end components. Owners frequently report a “clunking” sound when going over speed bumps or turning the steering wheel at low speeds.
This is often caused by worn-out sway bar links or lower control arm bushings. Replacing the sway bar links is a fantastic “entry-level” DIY project that only requires basic sockets and a jack, and it can significantly improve the quietness of your ride.
Another area to watch is the Electric Power Assist Steering (EPAS) rack. Ford issued recalls and extended warranties for some steering racks that would suddenly lose power assistance. If your steering feels heavy or you see a “Steering Loss” warning on the dash, check your VIN for open recalls.
Wheel Bearing Issues
Do you hear a “humming” or “growling” noise that changes pitch when you swerve slightly from side to side? That is a classic sign of a failing wheel bearing. On an AWD Explorer, the rear bearings are just as prone to failure as the fronts.
When replacing these, I highly recommend buying a complete hub assembly rather than trying to press a new bearing into the old knuckle. It saves hours of frustration and ensures that the ABS tone ring is properly aligned for the traction control system.
Always use a torque wrench to tighten the axle nut to the factory specification. An over-tightened or under-tightened nut will cause the new bearing to fail prematurely, sometimes within just a few hundred miles.
Optimizing Off-Road Performance and Safety
While the 2014 ford explorer limited awd isn’t a rock crawler like a Jeep Wrangler, it is surprisingly capable on forest service roads and beach sand. To get the most out of it, you need to understand the limitations of the unibody chassis.
Before heading off-pavement, ensure your tires are in good condition. The Limited trim often comes with 20-inch wheels, which have a shorter sidewall. This makes them more susceptible to “pinch flats” if you hit a sharp rock at high speed.
If you plan on frequent light off-roading, consider downsizing to 18-inch wheels with an All-Terrain tire. This provides more “meat” on the tire to absorb impacts and allows you to air down slightly for better flotation in soft sand.
Essential Recovery Gear
Even with Intelligent 4WD, you can still get stuck if you bottom out the vehicle in deep mud. Always carry a basic recovery kit that includes a kinetic snatch strap, a set of traction boards, and a folding shovel.
Remember that the Explorer does not have traditional frame-mounted tow hooks in the front. You must use the designated recovery points or a hitch-mounted shackle in the rear. Never pull from a suspension component, as you will likely bend a control arm or damage the EPAS rack.
If you are traveling solo in remote areas, a satellite communicator is a lifesaver. Cell service often drops out exactly when you need it most, and having a way to call for a tow or emergency services is non-negotiable for safety.
Brake System Maintenance for Heavy SUVs
Stopping a 5,000-pound SUV requires a lot of friction and heat dissipation. The 2014 ford explorer limited awd uses a vacuum-boosted four-wheel disc brake system that is generally very reliable, but it does require high-quality components.
When it comes time for a brake job, avoid the cheapest “economy” pads at the auto parts store. These heavy vehicles will cook cheap pads, leading to brake fade and warped rotors during long downhill descents or while towing a trailer.
Opt for a high-quality ceramic or semi-metallic pad designed for heavy-duty use. Also, make sure to clean and lubricate the slide pins on the calipers. If the pins seize, the pads will wear unevenly and can cause the vehicle to pull to one side during hard braking.
Bleeding the ABS Module
If your brake pedal feels “spongy” even after replacing the pads and rotors, you likely have air trapped in the system. On the 2014 model, air can sometimes get stuck inside the ABS hydraulic control unit.
Traditional bleeding might not be enough to clear this. You may need a scan tool capable of performing an “ABS Service Bleed,” which cycles the internal valves to purge any stubborn air bubbles. This is a critical safety step that ensures your emergency braking works when you need it most.
I recommend a full brake fluid flush every two years. Brake fluid is hygroscopic, meaning it absorbs moisture from the air. Over time, this water content can corrode the internal components of your expensive ABS module and master cylinder.
Frequently Asked Questions About 2014 ford explorer limited awd
What is the towing capacity of the 2014 Ford Explorer Limited AWD?
When properly equipped with the Class III trailer tow package, the 3.5L V6 model can tow up to 5,000 pounds. Without the factory tow package, the capacity is significantly lower (usually around 2,000 pounds) due to the lack of an engine oil cooler and proper wiring.
Does the 2014 Explorer Limited AWD have a spare tire?
Yes, most models come with a “temporary use” compact spare tire located under the load floor in the cargo area. If you are going off-road, keep in mind that a compact spare is not designed for rugged terrain and should only be used to get you to the nearest repair shop.
How can I improve the fuel economy of my Explorer?
The best way to boost MPG is to ensure your tires are properly inflated and your air filter is clean. Additionally, using the “Normal” mode on the Terrain Management dial ensures the system stays in front-wheel-drive as much as possible, reducing driveline parasitic loss.
Is the 2014 Ford Explorer Limited AWD good in the snow?
Absolutely. When switched to “Grass/Gravel/Snow” mode, the AWD system is very proactive. However, the system is only as good as your tires. For the best winter performance, a dedicated set of winter tires will outperform any all-season tire, regardless of the AWD system.
Final Thoughts on the 2014 Explorer Limited
Owning a 2014 ford explorer limited awd is a rewarding experience if you stay ahead of the maintenance curve. By ignoring the “lifetime” fluid claims and keeping a close eye on your cooling system, you can enjoy the luxury and utility of this SUV for many years.
Remember that most major failures give you a warning sign—whether it’s a faint smell, a new sound, or a slight change in how the steering feels. Being an attentive owner is the best tool in your toolbox. Don’t be afraid to get under the hood and check your fluids; it’s the simplest way to protect your investment.
Stay proactive with your repairs, use high-quality parts, and don’t hesitate to consult a professional for the complex internal engine work. Safe travels, and enjoy the capability of your Ford Explorer!
