Ford F150 Lariat 2014 – The Ultimate Owner’S Guide To Maintenance
The 2014 Ford F-150 Lariat represents the pinnacle of the twelfth-generation F-Series, blending high-end luxury features with the rugged capability expected of a workhorse. This guide provides a deep dive into maintaining its sophisticated powertrain options, troubleshooting common electrical gremlins, and selecting the best performance mods for off-road or towing use.
Owning a truck that feels as comfortable on a job site as it does on a cross-country road trip is a unique experience. However, keeping a high-mileage ford f150 lariat 2014 in peak condition requires more than just occasional oil changes and car washes.
Whether you are a seasoned DIY mechanic or a first-time truck owner, understanding the nuances of this specific model year is vital. We will explore the technical details that make this truck a legend and the maintenance steps that ensure it stays on the road for another decade.
This article provides a comprehensive roadmap for troubleshooting, upgrading, and preserving your vehicle. Let’s dive into the mechanical heart of this beast and see what makes it tick.
Choosing Your Power: The 5.0L Coyote vs. 3.5L EcoBoost
The 2014 model year offered two primary engines that dominate the market today. Each has a distinct personality and specific maintenance requirements that every owner should know.
The 5.0L Coyote V8: Traditional Reliability
The 5.0L V8 is a favorite among purists who love the classic truck sound and linear power delivery. It is a naturally aspirated engine, meaning it lacks the complexity of turbochargers, which often translates to lower long-term repair costs.
Commonly, these engines suffer from minor issues like coolant reservoir T-connector leaks. If you notice a small puddle of orange fluid near the front of the engine, check the O-rings in the quick-connect hoses first.
The 3.5L EcoBoost V6: Twin-Turbo Torque
If you prioritize towing capacity and low-end torque, the 3.5L EcoBoost is the powerhouse you need. It uses twin turbochargers to deliver V8-beating performance while maintaining decent fuel economy under light loads.
However, the EcoBoost is sensitive to spark plug gaps. To prevent a “misfire under load” or “shuddering” sensation during acceleration, many experts recommend gapping your plugs to 0.030 inches and replacing them every 30,000 miles.
Troubleshooting Common Issues in the ford f150 lariat 2014
Every vehicle has its quirks, and this specific truck is no exception. Identifying these issues early can save you thousands of dollars in shop labor and prevent unexpected breakdowns.
Transmission Lead Frame Failures
The 6R80 six-speed automatic transmission is generally robust, but it is known for molded lead frame issues. This can cause the truck to suddenly downshift into first gear while driving or display a “wrench” light on the dash.
Ford issued a recall for many of these units, so check your VIN with a local dealer. If you are out of warranty, replacing the lead frame involves dropping the transmission pan and valve body, a manageable task for a dedicated DIYer.
The “EcoBoost Shudder” and Intercooler Condensation
In humid conditions, the 3.5L EcoBoost intercooler can trap moisture. When you floor the gas, this moisture is sucked into the engine, causing a temporary misfire.
Many owners solve this by drilling a tiny “weep hole” (1/16th inch) in the lowest point of the intercooler. This allows the condensation to drain out naturally, preventing the engine from “choking” on water vapor during heavy acceleration.
Rear Sliding Window and Third Brake Light Leaks
The Lariat trim often features a power-sliding rear window. Over time, the seals can perish, or the third brake light housing can warp, allowing water to enter the cab.
If you notice damp carpet or a musty smell, inspect the third brake light first. Replacing the factory foam gasket with a high-quality butyl seal or a thicker aftermarket gasket is a permanent fix for this common nuisance.
Essential Maintenance for the ford f150 lariat 2014
To keep your truck running past the 200,000-mile mark, you must go beyond the basic dealership service intervals. High-quality fluids and proactive part replacement are your best friends.
Oil Selection and Filtration
For the 5.0L V8, a 5W-20 full synthetic oil is standard, while the 3.5L EcoBoost benefits significantly from 5W-30 full synthetic to protect the turbocharger bearings. Always use a Motorcraft FL-500S filter or an equivalent high-flow synthetic media filter.
Change your oil every 5,000 to 7,000 miles. While the truck has an “Intelligent Oil-Life Monitor,” waiting for it to hit 0% often means running on degraded oil, especially if you tow frequently.
Driveline and 4×4 Care
If your Lariat is a 4×4 model, don’t forget the transfer case and differentials. The ford f150 lariat 2014 uses an Electronic Shift-on-the-Fly (ESOF) system that relies on vacuum-actuated hubs (IWEs).
If you hear a grinding noise from the front wheels that disappears when you switch to 4WD, you likely have a vacuum leak. Check the check valve and the vacuum lines near the steering knuckles for cracks or clogs.
- Transfer Case: Use Motorcraft XL-12 or Mercon LV (check your manual for the specific build date).
- Rear Differential: Most Lariats have a 9.75-inch rear end requiring 75W-140 synthetic gear oil.
- Front Differential: Usually requires 80W-90 or 75W-90 gear oil.
Upgrading Your Off-Road and Towing Setup
The Lariat is a great platform for modifications. Whether you want to hit the trails or pull a heavy travel trailer, a few strategic upgrades can transform the driving experience.
Suspension and Leveling Kits
The factory rake (the front sitting lower than the rear) can be unsightly. A 2-inch leveling kit is the most popular mod for this truck, allowing you to fit 33-inch or even 35-inch tires with minor trimming.
For better ride quality, skip the plastic spacers and opt for adjustable leveling struts like the Bilstein 5100 series. These provide a much more controlled feel over washboard roads and during high-speed cornering.
Braking Performance
Towing with a ford f150 lariat 2014 can put immense strain on the factory brakes. If you feel a pulsation in the pedal, your rotors are likely warped from heat.
Upgrade to a set of drilled and slotted rotors paired with carbon-fiber ceramic pads. This combination offers better heat dissipation and a more aggressive “bite,” which is crucial when stopping a heavy load on a downhill grade.
Managing the MyFord Touch Infotainment System
The 2014 Lariat comes equipped with the Sync 2 / MyFord Touch system. While it was cutting-edge at the time, it can feel sluggish or glitchy by modern standards.
Software Updates and Reboots
If your screen freezes or your phone won’t connect, try a “Master Reset” in the settings menu. You should also check the Ford owner portal to ensure you are running the latest version of the Sync 2 software.
For those who want modern features like Apple CarPlay or Android Auto, the best solution is a Sync 3 hardware swap. This involves replacing the screen and APIM module with units from a 2016+ F-150, which is a direct “plug-and-play” upgrade for the 2014 Lariat.
Backup Camera Clarity
The backup camera on these trucks often becomes blurry due to moisture intrusion or lens oxidation. Before replacing the whole unit, try cleaning the lens with a plastic polish.
If the image is still distorted or “rainbowed,” the camera module itself is likely failing. Replacement is simple; you just need to pop the Ford emblem off the tailgate to access the mounting screws.
Interior Comfort and Leather Care
The Lariat’s leather interior is one of its best features, but it requires maintenance to prevent cracking. The 10-way power-adjustable seats are prone to wear on the driver’s side bolster.
Use a pH-balanced leather cleaner and conditioner every three months. This keeps the hide supple and prevents the UV rays from the sun from drying out the material, especially if you don’t have tinted windows.
Check the heated and cooled seat functions annually. These use a “TED” (Thermoelectric Device) and a small filter located under the seat. If the filter is clogged with dust, the cooling function will fail, and the heating will be less effective.
Frequently Asked Questions About the ford f150 lariat 2014
What is the maximum towing capacity of a 2014 F-150 Lariat?
Towing capacity varies based on the engine and rear-axle ratio. Generally, a properly equipped 3.5L EcoBoost with the Max Trailer Tow Package can pull up to 11,300 pounds. Always check the sticker on your driver’s side door jamb for your specific “Payload” and “GVWR” ratings.
Does the 2014 F-150 Lariat have a cabin air filter?
No, the 2009-2014 F-150 models did not come with a cabin air filter from the factory. However, the housing is often present but blocked off. Some DIYers choose to cut the plastic and install an aftermarket filter kit to improve air quality inside the cab.
Is the ford f150 lariat 2014 a reliable daily driver?
Yes, it is widely considered one of the most reliable modern trucks if maintained properly. The 2014 model was the final year of the twelfth generation, meaning Ford had worked out most of the “first-year” bugs seen in earlier 2011-2012 models.
How can I improve the fuel economy of my 2014 Lariat?
Keep your tire pressure at the recommended PSI and ensure your air filter is clean. For EcoBoost owners, keeping the spark plugs fresh and avoiding “jackrabbit” starts will have the biggest impact on your MPG. Using a high-quality tonneau cover can also slightly reduce aerodynamic drag.
