Whether you are a weekend warrior towing a boat or a DIYer looking to save on shop labor, understanding this vehicle’s unique architecture is vital. We will dive deep into the mechanical nuances that distinguish the Platinum trim from its lesser siblings.
In this article, we will cover critical cooling system checks, drivetrain longevity tips, and interior tech troubleshooting. By the end, you will have a clear roadmap for keeping your SUV in peak condition for the next hundred thousand miles.
The Heart of the Ford Explorer 2019 Platinum: The 3.5L EcoBoost
The 3.5L EcoBoost V6 is the crown jewel of this trim level, providing effortless passing power and impressive towing torque. However, twin-turbocharged engines generate significant heat, making thermal management your top priority during routine inspections.
To keep the turbos healthy, never skip an oil change and always use a high-quality full synthetic 5W-30 oil. Clean oil prevents carbon buildup on the turbocharger bearing housings, which is a common cause of premature failure in high-mileage engines.
I recommend changing your oil every 5,000 miles rather than following the “Intelligent Oil-Life Monitor” to its 10,000-mile limit. Shortening the interval is cheap insurance against the dreaded timing chain stretch often seen in these engines.
The Internal Water Pump Warning
One specific quirk of the 3.5L Duratec-based EcoBoost is the internal water pump, which is driven by the timing chain. If the internal seal fails, coolant can leak directly into the oil pan, potentially destroying the engine in minutes.
Regularly check your oil dipstick for a “milky” appearance and monitor your coolant reservoir levels closely. If you see the coolant level dropping with no visible external leaks, stop driving immediately and have the system pressure tested.
Spark Plug Maintenance for Turbo Engines
Turbocharged engines are sensitive to spark plug gap growth, which can lead to high-speed misfires or “stuttering” under heavy acceleration. For the ford explorer 2019 platinum, I suggest replacing spark plugs every 30,000 to 45,000 miles.
Use OE-spec Iridium plugs and ensure they are gapped correctly to.030 inches to maintain a crisp flame front. This simple DIY task keeps your fuel economy high and prevents unnecessary stress on the ignition coils.
Maintenance Essentials for Your Ford Explorer 2019 Platinum
Beyond the engine, the drivetrain of the Platinum trim requires specialized care to handle the 350 lb-ft of torque it produces. The Intelligent 4WD system is robust, but it relies on several components that many owners overlook during standard service.
The Power Transfer Unit (PTU) is responsible for sending power to the rear wheels, and it sits very close to the hot exhaust manifold. This heat causes the gear lubricant to break down and turn into a thick, sludge-like consistency over time.
Ford often lists this fluid as “lifetime,” but experienced mechanics know that changing the PTU fluid every 30,000 miles is essential. Use a vacuum pump to suck out the old 75W-140 synthetic gear oil and replace it with fresh fluid to prevent gear failure.
Transmission Fluid Care
The 6F55 6-speed automatic transmission is a heavy-duty unit designed to handle the EcoBoost’s power, but it still generates heat. Perform a “drain and fill” of the transmission fluid every 50,000 miles to keep the clutch packs engaging smoothly.
Avoid high-pressure flushes, as they can sometimes dislodge debris and clog the internal solenoids. A simple gravity drain and refill with Mercon V is usually all you need to keep the shifts feeling like new.
Brake System Upgrades
Given the weight of the ford explorer 2019 platinum, the factory brakes can sometimes feel a bit soft during heavy towing. Upgrading to ceramic brake pads and slotted rotors can significantly improve heat dissipation and reduce brake fade.
When you perform a brake job, don’t forget to grease the caliper slide pins with high-temperature silicone paste. This prevents “hanging” calipers, which can lead to uneven pad wear and warped rotors on heavy SUVs.
Optimizing the Terrain Management System
The Platinum trim features a sophisticated Terrain Management System that adjusts throttle response, shifting, and traction control for different surfaces. Understanding how to use these settings can save your drivetrain from unnecessary strain during off-road excursions.
The “Sand” mode, for example, holds gears longer and allows for more wheel spin to maintain momentum in soft terrain. Conversely, the “Grass/Gravel/Snow” mode starts the vehicle in a higher gear to prevent loss of traction on slippery surfaces.
If you find yourself on a steep descent, utilize the Hill Descent Control button located in the center of the terrain dial. This system uses the ABS module to pulse the brakes individually, allowing you to crawl down hills safely without locking the tires.
Suspension and Ride Quality
The 2019 Platinum comes standard with 20-inch wheels, which look great but can transmit more road vibration than smaller wheels. If your ride feels “jiggly” or harsh, check your tire pressure; even 2-3 PSI over the door placard can ruin the ride quality.
Inspect your front strut towers and rear shocks for signs of oil leaking, which indicates the seal has failed. Replacing worn shocks with high-quality monotube dampers can restore the “planted” feeling this SUV is known for.
Wheel Alignment and Tire Wear
Heavy AWD vehicles are notorious for eating through tires if the alignment is even slightly out of spec. Have your alignment checked annually, especially if you frequently drive on pothole-ridden city streets or gravel backroads.
Look for “cupping” or “feathering” on the inner edges of the tires, which often points to worn bushings or a bad toe setting. Rotating your tires every 5,000 miles is the best way to ensure you get the maximum life out of your expensive 20-inch rubber.
Interior Tech and Luxury Feature Troubleshooting
The interior of the ford explorer 2019 platinum is loaded with tech, including the Sync 3 infotainment system and multicontour massaging seats. While these features make long road trips a breeze, they can occasionally suffer from software “hiccups.”
If your Sync 3 screen becomes unresponsive or won’t connect to your phone, perform a “Master Reset” through the settings menu. You can also manually update the software via a USB drive by visiting Ford’s owner support website to download the latest files.
The massaging seats use a series of air bladders and a small compressor located under the seat cushion. If the massage function stops working, listen for a faint humming sound; if you hear it but feel no movement, a plastic air line may have disconnected.
Nirvana Leather Care
The Platinum trim uses “Nirvana” leather, which is softer and more porous than the leather found in lower trims. To prevent cracking and fading, use a pH-balanced leather cleaner and a high-quality conditioner every three months.
Avoid using “all-in-one” interior sprays that contain harsh silicones, as these can clog the pores of the leather and lead to a greasy finish. A dedicated leather conditioner keeps the hides supple and preserves that “new car” smell.
Sony Audio System Maintenance
The 500-watt Sony premium audio system is a standout feature, but the door speakers can sometimes develop rattles over time. Often, this isn’t a blown speaker, but rather a loose plastic door panel clip or a vibrating wiring harness.
If you hear a buzz during heavy bass tracks, you can often fix it by adding a small piece of foam tape behind the door panel. This is a simple DIY fix that saves you from a costly trip to the dealership for “diagnostic time.”
Towing and Utility: Getting the Most from Your SUV
With the Class III Towing Package, the 2019 Explorer Platinum is rated to pull up to 5,000 pounds. This makes it perfect for hauling a medium-sized camper or a pair of ATVs to the trailhead for a weekend of fun.
Always use a weight-distribution hitch if you are approaching the maximum towing capacity to keep the front wheels firmly on the ground. This improves steering response and prevents the “porpoising” effect that can happen on wavy highways.
Remember that towing puts extra stress on your engine oil and transmission fluid, so consider these “severe duty” conditions. If you tow frequently, I recommend cutting your fluid change intervals in half to account for the increased heat loads.
Trailer Wiring and Lighting
Before every trip, check your 7-pin connector for corrosion or bent pins, which can cause intermittent trailer light failure. A quick spray of electrical contact cleaner and a dab of dielectric grease will keep the connection reliable in wet weather.
If your trailer brakes aren’t engaging correctly, check the integrated trailer brake controller on the dashboard. You can adjust the “gain” setting to ensure the trailer slows down in sync with the vehicle without locking its wheels.
Frequently Asked Questions About Ford Explorer 2019 Platinum
What is the real-world fuel economy of the 2019 Platinum?
While the EPA estimates 16 city / 22 highway, real-world numbers often hover around 18 MPG combined. Driving with a “light foot” and keeping your tires properly inflated are the best ways to maximize your range between fill-ups.
Does the 2019 Explorer Platinum require premium fuel?
The 3.5L EcoBoost is designed to run on 87-octane regular fuel, but it will pull timing (reduce power) to prevent knocking. For maximum horsepower and the best performance while towing, using 91 or 93 octane premium fuel is highly recommended.
How do I know if my water pump is failing?
Look for white smoke from the exhaust, a sweet “syrup” smell inside the cabin, or a rising temperature gauge. Most importantly, check your oil for a “chocolate milk” consistency, which is a definitive sign of internal coolant leakage.
Is the 2019 Explorer Platinum a good off-roader?
It is very capable on forest service roads, beach sand, and light trails thanks to the Intelligent 4WD system. However, its low ground clearance and 20-inch wheels mean it is not intended for heavy rock crawling or deep mud bogging.
