Foundational Concepts of the ford f150 lariat 2019
The 2019 model year was a pivotal time for the F-Series, as Ford refined the aluminum-alloy body and the high-strength steel frame. The Lariat trim, specifically, sits above the XLT and below the King Ranch, offering features like dual-zone automatic temperature control and the Sync 3 infotainment system as standard equipment.
Under the hood, you typically find one of three main powerplants: the 2.7L EcoBoost, the 3.5L EcoBoost, or the legendary 5.0L Coyote V8. Each of these engines has a distinct personality and specific maintenance requirements. For instance, the twin-turbocharged EcoBoost engines rely heavily on clean oil to keep the turbo bearings lubricated, while the V8 is a naturally aspirated workhorse that thrives on high-rev performance.
Understanding your specific powertrain is the first step in successful ownership. The 10R80 10-speed automatic transmission is standard across most 2019 Lariat configurations, providing smooth shifts and improved fuel economy, but it does require specific fluid types and attention to shift logic updates from the dealer.
Common Maintenance Tasks for the ford f150 lariat 2019
Routine maintenance is the heartbeat of truck longevity. For the ford f150 lariat 2019, following the Intelligent Oil-Life Monitor is a good start, but many experts recommend a more aggressive schedule if you frequently tow or drive in dusty off-road conditions.
Oil Changes and Filter Selection
For the EcoBoost engines, use a high-quality full synthetic 5W-30 oil. The 5.0L V8 typically calls for 5W-20, though some high-mileage users prefer 5W-30 for better protection. Always use a Motorcraft FL-500S or equivalent high-flow filter to ensure the variable valve timing system receives adequate oil pressure.
The Critical Spark Plug Gap
Turbocharged engines are sensitive to spark plug wear. If you notice a slight stumble under heavy acceleration, it is time to check your plugs. For the 3.5L EcoBoost, many DIYers find that narrowing the gap to 0.028–0.030 inches helps prevent spark blowout under boost, leading to much smoother power delivery.
Coolant System Integrity
The 2019 models used Orange Antifreeze from the factory, but Ford has since transitioned to a Yellow Antifreeze (P-OAT) which is backward compatible. If you are flushing your system, ensure you use the updated yellow coolant to prevent the “silking” or clogging issues that occasionally plagued the older orange formula.
Troubleshooting the 10-Speed Transmission
The 10R80 transmission in the ford f150 lariat 2019 is a marvel of engineering, but it isn’t without its quirks. Some owners report “harsh shifts” or a “clunk” when downshifting from 10th to 8th gear. Often, this is a software issue rather than a mechanical failure.
Before you panic and head to a transmission shop, check if there are any Technical Service Bulletins (TSBs) related to the Transmission Control Module (TCM). A simple adaptive learning reset performed via a scan tool or by a technician can often smooth out those gear changes. This allows the computer to “re-learn” your driving style and adjust line pressures accordingly.
If you decide to check the fluid yourself, be aware that there is no traditional dipstick under the hood. You will need to crawl under the truck and remove a small 19mm cap on the passenger side of the transmission case. Use a fluid transfer pump to add Mercon ULV fluid, which is specifically designed for these ultra-low viscosity requirements.
Expert-Level Performance Upgrades and Off-Road Setup
The Lariat is a fantastic platform for modifications. Because it comes with a high level of interior comfort, many owners focus their budget on the suspension and wheels to create a more aggressive stance without sacrificing the “Lariat ride.”
Leveling Kits vs. Full Lift Kits
A 2-inch leveling kit is the most popular mod for this truck. It removes the factory “rake” (where the front sits lower than the rear) and allows for 33-inch or even 35-inch tires with minor trimming. For those hitting the trails, a coilover upgrade from brands like Fox or Bilstein is superior to a simple spacer, as it improves damping and prevents the “bouncy” feel on washboard roads.
EcoBoost Performance: The “Catch Can”
If you have a 2.7L or 3.5L engine, consider installing an oil catch can. These engines use direct injection, which can lead to carbon buildup on the intake valves over time. A catch can intercepts oil vapors before they reach the intake, keeping your valves clean and maintaining your fuel efficiency and power output over the long haul.
Lighting and Electrical
While the Lariat often comes with LED lighting, many owners find the factory fog lights lacking. Upgrading to SAE-compliant LED pods in the bumper pockets can significantly improve visibility during night drives or foggy morning commutes. If you plan on adding multiple accessories, look into a switched power distribution block to keep your wiring clean and safe.
Common Mistakes and How to Avoid Them
One of the most frequent mistakes ford f150 lariat 2019 owners make is neglecting the plastic oil pan drain plug. These trucks moved away from traditional metal bolts to a yellow plastic “turn-and-pull” plug. If you over-tighten this or reuse a damaged O-ring, you will end up with a persistent leak on your driveway.
Another pitfall is ignoring the panoramic sunroof tracks. If your Lariat is equipped with the twin-panel moonroof, the tracks require regular cleaning and lubrication with Krytox grease. Failure to do this can result in the plastic guides snapping, which is a very expensive repair involving the removal of the entire headliner.
Finally, be cautious with “cheap” aftermarket LED bulb replacements in halogen housings. This can scatter light and blind oncoming drivers. Always opt for complete housing replacements or high-quality bulbs specifically designed to mimic the filament location of the original halogen bulbs to maintain a safe beam pattern.
Safety Systems and Technology Maintenance
The 2019 Lariat is packed with Advanced Driver Assistance Systems (ADAS). This includes Pre-Collision Assist and the Blind Spot Information System (BLIS). These systems rely on sensors located behind the front bumper and in the taillights. If you install an aftermarket steel bumper or a heavy-duty tow hitch, ensure you aren’t blocking these sensors.
Keep your Sync 3 system updated via Wi-Fi to ensure that Apple CarPlay and Android Auto function correctly. Software glitches in the infotainment system can sometimes be resolved by a “Master Reset” in the settings menu, which clears the cache and restores factory responsiveness. This is a common fix for lagging maps or Bluetooth pairing issues.
Frequently Asked Questions About the ford f150 lariat 2019
What is the towing capacity of the ford f150 lariat 2019?
Depending on the engine and rear-axle ratio, a ford f150 lariat 2019 can tow between 7,000 and 13,200 pounds. The 3.5L EcoBoost with the Max Trailer Tow Package offers the highest rating, making it a favorite for those pulling large travel trailers or horse trailers.
How often should I change the transmission fluid?
While Ford suggests a long interval, many enthusiasts and mechanics recommend changing the Mercon ULV fluid every 50,000 to 60,000 miles, especially if you engage in heavy towing. This helps prevent the buildup of friction material that can clog the small passages in the valve body.
