Understanding the Engine Options in the ford f150 lariat 2013
The 2013 model year was a pivotal time for Ford, offering two very different but equally capable powerplants for the Lariat trim. Choosing the right one—or knowing how to care for the one you have—is the first step in long-term ownership. Each engine has its own set of personality traits and maintenance requirements that you should monitor closely.
The 5.0L “Coyote” V8: The Reliable Workhorse
The 5.0L V8 is a favorite among traditionalists for its linear power delivery and classic exhaust note. It is generally considered a “bulletproof” engine, but it does require attention to the cooling system and oil quality. I always recommend using a high-quality synthetic motor oil to keep the variable cam timing components lubricated and functioning correctly.
One common issue with the 5.0L in the ford f150 lariat 2013 is the coolant “T-connector” leak. The O-rings inside these plastic connectors tend to flatten over time, leading to slow leaks that can cause overheating. If you see orange or pink crusty residue near the top of the engine, it is time to replace those seals or the entire hose assembly.
The 3.5L EcoBoost V6: Twin-Turbo Torque
If your Lariat is equipped with the 3.5L EcoBoost, you have a torque monster capable of out-towing many V8s. However, turbocharging adds complexity and heat to the engine bay. These engines are notoriously hard on spark plugs, which can lead to a “shudder” under heavy acceleration if the gap is too wide.
For the best performance, I suggest changing your spark plugs every 30,000 to 40,000 miles rather than waiting for the 100,000-mile factory interval. Always use a feeler gauge to ensure the gap is set strictly to 0.030 inches. This simple DIY task can prevent ignition coils from burning out prematurely and keep your fuel economy high.
Addressing the 6R80 Transmission and Lead Frame Issues
The 6R80 six-speed automatic transmission found in the ford f150 lariat 2013 is generally robust, but it has one specific Achilles’ heel. Many owners report the truck suddenly downshifting into first gear at highway speeds or the speedometer dropping to zero. This is usually caused by a failing molded lead frame inside the transmission.
The lead frame houses the output shaft speed sensor, and when it fails, the truck’s computer loses track of how fast you are going. Ford issued a recall for this, so check your VIN to see if your truck has been serviced. If you are doing this repair yourself, you will need to drop the transmission pan and replace the internal plastic frame that holds the sensors.
While you are in there, always replace the transmission filter and use Mercon LV fluid. Do not use generic fluids, as the 6R80 is very sensitive to viscosity. A fresh filter and fluid can solve many “clunky” shifting issues and extend the life of your torque converter significantly.
Troubleshooting the MyFord Touch Infotainment System
The Lariat trim often comes with the 8-inch MyFord Touch screen, which was cutting-edge in 2013 but can be buggy today. If your screen is lagging, freezing, or failing to connect to your phone, the first step is a Master Reset. You can find this option in the system settings menu under the “General” tab.
If a reset doesn’t work, check for software updates. You can download the latest version of Sync 2 onto a USB drive and install it yourself. This often fixes Bluetooth connectivity issues and improves the responsiveness of the navigation system. It is a simple way to modernize the interior feel of your ford f150 lariat 2013.
For those who find the factory system too slow, many owners opt for a Sync 3 upgrade kit. This involves replacing the physical screen and APIM (Accessory Protocol Interface Module) behind the dash. It allows for Apple CarPlay and Android Auto, which makes the truck feel much more modern during long road trips.
Maintaining the 4WD System and Integrated Wheel Ends (IWE)
If you take your Lariat off-road or live in a snowy climate, the 4WD system needs regular checks. A common “grinding” noise coming from the front wheels is often a sign of failing Integrated Wheel Ends (IWE). These are vacuum-operated hubs that engage and disengage the front axles.
When the vacuum lines leak or the check valve fails, the hubs try to engage while you are driving in 2WD, causing a metal-on-metal grinding sound. You can test this by switching to 4WD; if the noise stops, the IWE system is the culprit. Replacing the vacuum check valve is a five-minute, ten-dollar fix that solves 80% of these problems.
Don’t forget to change the fluid in your transfer case and front differential every 60,000 miles. Use a high-quality 75W-85 gear oil for the front diff and the specific XL-12 transfer case fluid. Keeping these gears lubricated is essential for preventing expensive mechanical failures when you are miles away from the nearest paved road.
Essential Suspension and Brake Upgrades for Off-Roaders
The factory suspension on the ford f150 lariat 2013 is tuned for comfort, but it can feel a bit “floaty” when carrying a heavy load or hitting washboard trails. Upgrading to monotube shocks, like the Bilstein 5100 series, is one of the best bangs for your buck. These shocks improve handling and can even level the front of the truck for a more aggressive stance.
When it comes to stopping power, the F-150 is a heavy beast. If you notice a pulsating feeling in the pedal, your brake rotors are likely warped. I recommend upgrading to slotted and drilled rotors with ceramic pads. These dissipate heat much better than the OEM blanks, especially when you are descending steep mountain grades with a trailer.
Check your brake lines for any signs of cracking or swelling. Rubber lines can soften over time, leading to a “mushy” brake pedal. Replacing them with stainless steel braided lines provides a firmer pedal feel and better protection against trail debris. This is a vital safety step for anyone planning to push their truck in rugged environments.
Preventative Maintenance Schedule for Long-Term Reliability
To keep your truck running past the 200,000-mile mark, you must go beyond the basic oil change. Creating a preventative maintenance log helps you stay ahead of failures. Start by inspecting your serpentine belt and tensioner every 15,000 miles for signs of wear or squeaking.
- Every 5,000 Miles: Change oil and filter, rotate tires, and check brake pad thickness.
- Every 30,000 Miles: Replace engine air filter and cabin air filter; inspect spark plugs (EcoBoost).
- Every 60,000 Miles: Replace transmission fluid and filter, transfer case fluid, and differential gear oil.
- Every 100,000 Miles: Flush the cooling system, replace the water pump, and install new spark plugs (V8).
Don’t overlook the battery terminals. Fords of this era are sensitive to voltage drops, which can cause phantom electrical issues. Clean any corrosion with a wire brush and a mixture of baking soda and water. Applying a thin layer of dielectric grease can prevent future buildup and ensure a strong start every morning.
Frequently Asked Questions About the ford f150 lariat 2013
What is the most common engine problem for the 2013 F-150?
For the 3.5L EcoBoost, the most common issue is spark plug fouling and moisture buildup in the intercooler, which can cause a misfire. For the 5.0L V8, coolant leaks at the T-connector and water pump are the most frequent complaints. Regular inspections can catch these before they leave you stranded.
Can I tow a 10,000-pound trailer with my Lariat?
Yes, but it depends on your specific gear ratio and payload capacity. Most 2013 Lariats with the Max Tow Package can handle between 9,000 and 11,300 pounds. Always check the door jamb sticker for your truck’s specific Gross Combined Weight Rating (GCWR) to ensure you are towing safely.
Is the 2013 F-150 Lariat a good truck for off-roading?
The Lariat is a very capable platform, especially if equipped with the 4×4 package and an electronic locking rear differential. While it is larger than a dedicated trail rig, a simple 2-inch leveling kit and a set of all-terrain tires make it excellent for overland travel and forest service roads.
How do I fix the “shudder” under acceleration?
On the EcoBoost models, this is almost always related to the spark plugs or ignition coils. Ensure your plugs are gapped to 0.030 inches. If the shudder persists, you may need to clean your MAP sensors with specialized electronic cleaner or check the intercooler for accumulated condensation.
