Ford Explorer 2019 – The Essential Guide To Maintenance, Common
The 2019 Ford Explorer represents the final year of the fifth-generation (U502) platform, offering a refined blend of towing capacity and family-friendly utility. This guide provides actionable insights into preventive maintenance, critical mechanical fixes, and off-road enhancements to ensure your vehicle remains reliable for years to come.
Finding a balance between a rugged trail machine and a comfortable family hauler is no easy task. You likely chose the ford explorer 2019 because it promises to handle both the school run and the occasional dirt path with ease.
However, keeping this SUV in peak condition requires a deeper understanding than what you will find in a basic owner’s manual. We will cover the specific mechanical quirks of this model year and how you can perform your own upgrades safely.
By the end of this guide, you will have a clear roadmap for maintenance, troubleshooting common failures, and prepping your rig for your next big adventure. Let’s dive into the technical details that every owner and DIYer needs to know.
Engine Options and Powertrain Dynamics
The 2019 lineup offered three distinct engines, each with its own maintenance profile and performance characteristics. Understanding which one sits under your hood is the first step toward effective DIY care.
The 3.5L Ti-VCT V6 (Base Engine)
The naturally aspirated 3.5L Cyclone V6 is a workhorse known for its longevity, provided you watch the cooling system. It produces 290 horsepower and is often found in the base and XLT trims.
This engine uses a mechanical water pump driven by the timing chain. Because the pump is internal, a leak can allow coolant to mix with the engine oil, which often leads to catastrophic engine failure if not caught early.
Check your oil dipstick weekly for a “milky” appearance. If you see a drop in coolant levels without a visible external leak, stop driving immediately and inspect the water pump weep hole behind the alternator.
The 2.3L EcoBoost Four-Cylinder
The 2.3L EcoBoost offers a great balance of torque and fuel efficiency, making it popular for daily drivers. It utilizes a twin-scroll turbocharger to provide 280 horsepower and 310 lb-ft of torque.
Since this is a Direct Injection (DI) engine, it is susceptible to carbon buildup on the intake valves. Over time, this buildup can cause rough idling and decreased fuel economy.
To mitigate this, use a high-quality synthetic oil and consider installing a “catch can” system. This device captures oil vapors before they reach the intake, keeping your valves cleaner for longer intervals.
The 3.5L EcoBoost V6 (Sport and Platinum)
Found in the Sport and Platinum trims, this twin-turbocharged powerhouse delivers 365 horsepower. It transforms the Explorer into a surprisingly quick SUV capable of heavy towing.
Heat management is critical for these turbocharged engines. Ensure you are using the correct 5W-30 motor oil and changing it every 5,000 miles, regardless of what the Intelligent Oil-Life Monitor suggests.
High-heat environments can degrade the oil faster, leading to turbocharger bearing wear. Always let the engine idle for 30-60 seconds after a long highway haul to allow the turbos to cool down properly.
Common Mechanical Challenges for the ford explorer 2019
Every vehicle has its “weak links,” and the 2019 model is no exception. Knowing these issues ahead of time allows you to budget for repairs or perform preventive maintenance before a breakdown occurs.
PTU (Power Transfer Unit) Overheating
The Intelligent 4WD system relies on a Power Transfer Unit to send torque to the rear wheels. In the ford explorer 2019, the PTU holds a very small amount of gear oil (about 18 ounces).
Ford originally claimed this fluid was “lifetime,” but real-world experience shows it breaks down due to heat. When the oil degrades, it turns into a thick, “sludge-like” substance that can cause the unit to seize.
If you smell a “propane-like” or burnt gear oil odor after driving, your PTU is likely overheating. We recommend replacing the PTU fluid every 30,000 miles using a 75W-140 full synthetic gear lube.
Front Suspension and Wheel Bearing Wear
The Explorer is a heavy vehicle, weighing nearly 5,000 pounds. This mass puts significant stress on the front suspension components, particularly the lower control arm bushings and wheel bearings.
Listen for a “humming” or “growling” noise that changes pitch when you turn the steering wheel. This is a classic sign of a failing wheel hub assembly.
When replacing these, always use a torque wrench to tighten the axle nut to the factory specification (221 lb-ft). Over-tightening or under-tightening will lead to premature bearing failure within months.
Rear Suspension “Toe Link” Issues
Ford issued several recalls regarding the rear suspension toe links on this generation. These links help maintain rear-wheel alignment and stability.
A fractured toe link can cause a sudden loss of steering control, especially during high-speed cornering. Check your VIN on the NHTSA website to ensure all recall work has been completed by a certified dealer.
Even if the recall was performed, inspect the boots on these links during every oil change. If the rubber is cracked, moisture will enter the joint and cause rapid wear.
Routine Maintenance for Longevity
A proactive maintenance schedule is the difference between a 100,000-mile car and a 200,000-mile car. For the DIY mechanic, these tasks are straightforward and highly rewarding.
Oil and Filter Changes
Use a Motorcraft FL-500S or equivalent high-drainage filter. For the EcoBoost engines, full synthetic oil is mandatory to protect the turbocharger internals from extreme heat.
Drain the oil while the engine is warm to ensure all contaminants are flushed out. Always replace the drain plug gasket to prevent annoying slow leaks on your driveway.
Transmission Fluid Service
The 6F55 6-speed automatic transmission is generally reliable but benefits from fresh fluid. We suggest a “drain and fill” every 45,000 miles using MERCON V or MERCON LV fluid as specified by your dipstick.
Avoid “flushing” machines that use high pressure, as they can dislodge debris and clog internal solenoids. A simple gravity drain and refill is much safer for high-mileage units.
Coolant System Maintenance
The 2019 model uses Orange-colored coolant (or the newer Yellow-colored backward-compatible fluid). Mixing different types of coolant can lead to “gel” formation, which blocks the heater core.
Test your coolant’s pH and freeze point annually. If the coolant becomes acidic, it will begin to eat away at the internal water pump seals and the radiator core.
- Park on a level surface and let the engine cool completely.
- Open the radiator drain petcock and collect the old fluid.
- Refill with a 50/50 mix of concentrated coolant and distilled water.
- Run the engine with the heater on high to “burp” any trapped air bubbles.
Off-Road Capabilities and Terrain Management
While not a dedicated rock crawler, the Explorer is surprisingly capable on fire roads, sand, and snow. The Terrain Management System (TMS) allows you to optimize the 4WD system for different conditions.
Optimizing the TMS Dial
The dial on the center console adjusts throttle response, transmission shift points, and the electronic locking differentials. “Sand Mode” allows for more wheel spin to maintain momentum.
In “Mud/Ruts Mode,” the system stays in lower gears longer and increases steering sensitivity. Use “Grass/Gravel/Snow Mode” to dampen throttle response and prevent tires from breaking traction on slick surfaces.
Tire Pressure and Selection
If you plan on frequent off-road excursions, upgrade from standard highway tires to a mild All-Terrain (A/T) tire. Look for a size like 265/60R18 for a bit more sidewall cushion.
When driving on soft sand, “airing down” your tires to 18-20 PSI increases the footprint and prevents the vehicle from digging in. Always carry a portable air compressor to reinflate before hitting the pavement.
Ground Clearance and Protection
The 2019 model has a relatively low front air dam designed for aerodynamics. This plastic piece is the first thing to break when driving over obstacles.
Many enthusiasts remove the lower portion of the air dam to improve the approach angle. Just be aware that this might slightly decrease your highway fuel economy by 1-2 MPG.
Performance Upgrades and DIY Modifications
If you want to personalize your SUV, there are several effective modifications that improve both aesthetics and utility without compromising daily drivability.
Suspension Leveling Kits
A 2-inch front leveling kit is a popular mod for the ford explorer 2019. It eliminates the factory “rake” (where the front sits lower than the rear) and provides room for larger tires.
Installing a strut spacer kit is a job a confident DIYer can handle in a weekend. You will need a floor jack, jack stands, and a basic socket set.
Always get a professional alignment immediately after installing a leveling kit. Changing the strut height alters the camber and toe settings, which will ruin your tires in a matter of weeks.
Lighting Upgrades
The factory halogen fog lights are often underwhelming in heavy rain or snow. Replacing them with LED projector pods significantly improves visibility.
For those who camp, adding a “ditch light” bracket to the hood hinges allows you to mount small LED cubes. These illuminate the sides of the trail, helping you spot wildlife or obstacles at night.
Brake System Enhancements
If you tow a trailer or boat, the factory brakes can suffer from “brake fade” on long descents. Upgrading to carbon-fiber ceramic brake pads and slotted rotors helps dissipate heat faster.
When bleeding your brakes, use a DOT 4 LV (Low Viscosity) brake fluid. This ensures the ABS and stability control systems can react quickly in emergency situations.
- Clean the hub surface with a wire brush before installing new rotors.
- Apply high-temp brake grease to the slider pins.
- Ensure the “ears” of the pads move freely within the caliper bracket.
Safety Features and Buyer Guidance
The 2019 model was available with the Safe and Smart Package, which included adaptive cruise control and lane-keeping assist. These systems rely on cameras and radar sensors.
If you have a cracked windshield, ensure the replacement glass is “OEM-spec.” Aftermarket glass can sometimes distort the camera’s view, causing the lane-keeping system to malfunction.
When buying a used model, always check the service history for PTU and transmission fluid changes. A vehicle used for heavy towing without frequent fluid swaps is a risky investment.
Look for signs of rust on the hood’s leading edge. This generation was known for aluminum corrosion issues where the paint may bubble. Catching this early allows for a simple touch-up before it spreads.
Frequently Asked Questions About the ford explorer 2019
How often should I change the spark plugs?
For the non-turbo 3.5L engine, every 100,000 miles is standard. However, for the EcoBoost engines, we recommend changing them every 45,000 to 60,000 miles. Turbocharged engines are harder on plugs, and a worn gap can cause misfires under heavy load.
Is the 2019 model better than the 2020 model?
The 2019 is the last year of the front-wheel-drive based platform, while the 2020 shifted to a rear-wheel-drive layout. Many owners prefer the 2019 because the platform was “mature,” meaning most of the first-year production bugs had been worked out by then.
Can I tow a camper with my Explorer?
Yes, but check your specific trim. When properly equipped with the Class III Trailer Tow Package, the ford explorer 2019 can tow up to 5,000 pounds. Always use a weight-distributing hitch for trailers over 3,000 pounds to maintain steering control.
Why is my backup camera screen blue or blurry?
This is a common electrical glitch often caused by a failing camera module or a loose connection in the liftgate wiring harness. Sometimes a “master reset” of the SYNC 3 system fixes it, but usually, the camera hardware needs replacement.
Conclusion: Keeping Your Explorer Trail-Ready
The ford explorer 2019 is a versatile tool that rewards owners who take a “maintenance-first” approach. By addressing the PTU fluid, watching for water pump issues, and choosing the right upgrades, you can enjoy this SUV for many years.
Whether you are tackling a DIY brake job or prepping for a cross-country camping trip, always prioritize safety. Use the right tools, follow torque specifications, and never hesitate to consult a professional for complex internal engine work.
Take pride in your machine, stay on top of the small fixes, and your Explorer will be ready for whatever the road—or the trail—throws your way. Stay safe and stay comfortable!
