This guide provides actionable advice on managing its unique AWD system, preventing catastrophic engine failure from internal water pump leaks, and troubleshooting the MyFord Touch interface.
Owning a ford explorer 2013 limited means you have a vehicle that balances family-friendly utility with a high level of interior refinement. Whether you are navigating snowy highways or hauling gear for a weekend camping trip, this SUV is designed to handle diverse environments with ease.
However, as these vehicles age, they develop specific mechanical needs that differ from standard trucks or sedans. This article provides a deep dive into the technical nuances of the fifth-generation Explorer, offering the “pro” insights you need to keep your rig running strong.
We will explore everything from critical fluid intervals to suspension upgrades, ensuring you have a clear roadmap for DIY success. By the end of this guide, you will know exactly what to look for under the hood and how to avoid the most common pitfalls of this specific model.
The Heart of the Machine: Engine Options and Care
The Limited trim usually features the 3.5L Ti-VCT V6 engine, though some models may carry the 2.0L EcoBoost four-cylinder. The 3.5L V6 is a workhorse, but it has a design quirk that every owner must monitor: the internal water pump.
Unlike most vehicles where the water pump is driven by an external belt, this engine uses the timing chain to drive the pump. If the pump seal fails, coolant can leak directly into the oil pan, leading to engine sludge or immediate bearing failure.
To prevent this, inspect the “weep hole” located behind the alternator on the passenger side of the block. If you see any signs of orange or green crusty residue, your water pump is failing. Replace it immediately to save your entire engine from destruction.
For those with the 2.0L EcoBoost, keep a close eye on carbon buildup on the intake valves. Since this is a direct-injection engine, fuel does not wash over the valves to clean them. Using a high-quality synthetic oil and a Top Tier fuel can help mitigate this common issue.
Essential Maintenance for Your ford explorer 2013 limited
Routine maintenance is the backbone of vehicle longevity, especially for a heavy SUV like the ford explorer 2013 limited. While the owner’s manual suggests long intervals, experienced technicians recommend a more proactive approach to fluid changes.
Change your engine oil every 5,000 to 7,500 miles, even if the “Oil Life Monitor” says you have more time. Use a 5W-20 weight oil for the V6 or 5W-30 for the EcoBoost, and always opt for a high-quality silicone-valved filter to prevent dry starts.
Transmission health is equally vital for this model’s 6F55 or 6F35 six-speed automatic. Ford claims the fluid is “fill-for-life,” but we recommend a drain and fill every 30,000 to 45,000 miles. Fresh Mercon V or LV fluid ensures the solenoids stay clean and shifts remain crisp.
- Air Filter: Inspect every 15,000 miles; replace if dark or clogged with trail dust.
- Cabin Filter: Located behind the glovebox; change annually to prevent “musty AC” smells.
- Spark Plugs: Replace at 100,000 miles, but check them at 60,000 for signs of fouling.
Don’t forget the braking system, which works hard to stop this 4,500-pound vehicle. Flush the DOT 4 brake fluid every two years to remove moisture. This prevents internal caliper corrosion and maintains a firm, responsive pedal feel during heavy towing or mountain descents.
Addressing the “Lifetime Fluid” Myth in the PTU
If your ford explorer 2013 limited is equipped with Intelligent 4WD, it uses a Power Transfer Unit (PTU) to send torque to the rear wheels. This component is notorious among DIYers because it sits very close to the hot exhaust manifold.
The heat causes the gear oil inside the PTU to thicken into a “black sludge” or “molasses” consistency. Ford originally stated this fluid never needs changing, but many units fail prematurely due to lubrication loss. If you smell a “propane-like” odor after driving, your PTU fluid is likely cooked.
Since the 2013 model often lacks a drain plug, you may need to use a fluid extractor to suck the old oil out through the fill hole. Replace it with a high-performance 75W-140 full synthetic gear oil. This simple task can save you thousands in replacement costs for a new transfer case.
Check the PTU seals for leaks regularly. If you see oil “misting” around the passenger side CV axle, the seal may be compromised. Replacing a seal is a tedious job, but it is far cheaper than replacing the entire gear assembly once it runs dry.
Step-by-Step PTU Fluid Refresh
- Lift the front of the vehicle safely on jack stands.
- Locate the PTU fill plug on the passenger side, near the exhaust.
- Remove the plug using a 3/8-inch ratchet or hex key.
- Insert a thin suction tube and extract as much old fluid as possible.
- Pump in fresh 75W-140 synthetic oil until it starts to weep from the fill hole.
Suspension and Steering: Handling the Fifth-Gen Weight
The fifth-generation Explorer platform is heavy, which puts significant stress on the front-end components. Owners often report “clunking” sounds when driving over speed bumps or turning the steering wheel at low speeds. This is usually caused by worn sway bar links or lower control arm bushings.
Another area of concern is the Electronic Power Assisted Steering (EPAS) rack. If you experience a “Power Steering Assist Fault” warning, it may be a software glitch or a hardware failure. Always check the battery health first, as low voltage can trigger false steering codes.
For the rear suspension, the ford explorer 2013 limited has been subject to recalls regarding the rear suspension toe links. These links can fracture under high stress, leading to a sudden loss of steering control. Ensure your local dealership has performed the latest recall service on these parts.
If you plan on light off-roading or towing, consider upgrading to heavy-duty struts and shocks. High-pressure gas-charged units can reduce the “boaty” feeling often associated with the stock suspension. This improves stability when the vehicle is fully loaded with passengers and cargo.
Troubleshooting the MyFord Touch and Interior Electronics
The Limited trim is packed with technology, including the MyFord Touch system powered by SYNC. While advanced for its time, it can be prone to lagging, freezing, or “black screen” issues. Most of these problems can be resolved with a master reset or a software update.
To perform a hard reset, go to the “Settings” menu, select “System,” and then “Master Reset.” This will wipe your saved Bluetooth devices and navigation history, but it often clears out the “digital cobwebs” that slow the system down over time.
If your backup camera shows a distorted image or a “Camera Unavailable” message, the culprit is often a loose connection in the liftgate. You can remove the interior trim panel of the hatch to inspect the wiring harness. Applying dielectric grease to the connector can prevent moisture from causing signal interference.
The rear power-folding seats are another Limited-specific feature to watch. If they fail to move, check for obstructions in the folding path, like small toys or stones. Usually, the motor hasn’t failed; rather, the “pinch protection” sensor has been tripped and needs a manual reset.
Safety First: Brakes, Tires, and Visibility
Safety is paramount for any family vehicle, and the ford explorer 2013 limited offers several advanced features that require attention. The rear inflatable seatbelts, for example, are thicker than standard belts and require specific care to ensure the internal airbags remain functional.
Keep an eye on your tire pressure monitoring system (TPMS). In colder climates, the sensors in the wheels can fail as their internal batteries die. If you see a TPMS warning light, use an OBD-II scanner to identify which specific wheel is failing before heading to the tire shop.
Visibility is also key, especially given the thick A-pillars of this model. Ensure your blind-spot monitoring (BLIS) sensors, located behind the rear bumper corners, are kept clean. Mud or heavy snow buildup on the bumper can block the radar signals, leading to false alerts or system deactivation.
- Headlights: The projector housings can dim over time; consider high-output halogen or LED replacements.
- Wiper Blades: Use beam-style blades for better contact on the large, curved windshield.
- Brake Lines: Inspect for rust if you live in the “Salt Belt,” as the rear lines are exposed to road spray.
Frequently Asked Questions About the ford explorer 2013 limited
Is the 2013 Ford Explorer Limited reliable for high mileage?
Yes, provided you address the water pump and PTU fluid issues early. Many owners reach 200,000 miles by being proactive with cooling system maintenance and transmission fluid changes. Neglecting these can lead to expensive failures.
What type of fuel should I use in my Explorer Limited?
The 3.5L V6 runs perfectly fine on 87-octane regular unleaded. If you have the 2.0L EcoBoost and are towing or driving in hot weather, 91 or 93-octane premium fuel can help prevent “engine knock” and improve overall performance.
How do I fix a “Power Steering Assist Fault”?
First, check your battery voltage; a weak battery is a common cause. If the battery is good, you may need a dealership to perform a software “reflash.” In the worst-case scenario, the entire steering rack (EPAS) may need replacement.
Can I tow a trailer with my 2013 Explorer Limited?
When properly equipped with the Class III Tow Package, the V6 model can tow up to 5,000 lbs. Always use the “Tow/Haul” mode on the shifter to adjust transmission shift points and prevent the brakes from overheating on long downgrades.
Why is my AC only blowing air through the defroster?
This is usually a sign of a failed blend door actuator. These small electric motors control where the air is directed. They are a common failure point in Fords of this era and often make a clicking sound behind the dashboard when they fail.
