How Ford schedules service: Intelligent Oil-Life Monitor

Ford uses the Intelligent Oil-Life Monitor (IOLM) to determine when oil changes are due based on actual driving load — not just mileage. Ford's published cap is 10,000 miles or 1 year, whichever comes first. The schedule below reflects Ford's Normal service intervals; F-Series trucks and Super Duty have additional towing-specific items.

A component within the fuel pump electric module (PEM) may overheat causing a loss of electrical power to the fuel pump.

Risk: A loss of power to the fuel pump will cause the engine to stall or prevent the vehicle from starting, increasing the risk of a crash.

Fix: Ford will notify owners, and dealers will inspect the fuel PEM part number and replace the fuel PEM, as necessary, free of charge. The recall began on December 1, 2016. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 16S31.

Risk: A fuel leak in the presence of an ignition source may result in a fire.

Fix: Ford will notify owners, and dealers will replace the fuel delivery module, free of charge. The recall began on December 21, 2015. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 13S04-S1.

STEERING:ELECTRIC POWER ASSIST SYSTEM

Campaign #15V340000 · 02/06/2015

The affected vehicles have electric power steering assist systems that may shut down as a result of a steering motor sensor fault.

Risk: If the vehicle experiences a loss of power steering assist, extra steering effort will be required at lower speeds, increasing the risk of a vehicle crash.

Fix: Ford will notify owners, and dealers will check the Power Steering Control Module (PSCM) for Diagnostic Trouble Codes (DTC).

In the affected vehicles, the halfshaft retention circlip may not have been properly installed, and as a result, the halfshaft may move outward and disengage from the linkshaft while driving and without prior warning.

Risk: If the halfshaft and linkshaft become disengaged while driving, power will no longer be transmitted to the wheels, increasing the risk of a vehicle crash. Additionally, if the parking brake is not applied before exiting the vehicle, the vehicle may roll away despite the transmission being placed in 'Park', increasing the risk of injury to exiting occupants and bystanders.

Fix: Ford will notify owners, and dealers will inspect the vehicles to make sure that the halfshaft is properly retained. If it is not, dealers will replace the linkshaft and also replace the halfshaft if it shows evidence of spline damage, free of charge. The recall began on August 4, 2014.

Essential maintenance

Critical for safety and preventing major damage

🛢️

Engine Oil & Filter

Every 7,500 mi

Replace synthetic-blend or full-synthetic Motorcraft oil per the IOLM, or every 7,500-10,000 miles. EcoBoost engines require full synthetic; Coyote 5.0L V8 specifies SAE 5W-30.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

🔄

Tire Rotation

Every 10,000 mi

Rotate tires every 10,000 miles, or with every other oil change. F-150 4x4 owners should rotate every 5,000-7,500 miles to even out drivetrain bias wear.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

🛑

Brake Inspection

Every 10,000 mi

Inspect brake pads, rotors, and brake fluid level every 10,000 miles. Front pads on F-150 and Explorer typically last 40,000-60,000 miles.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

🧪

Brake Fluid

Every 45,000 mi

Ford specifies brake fluid replacement on an inspection basis, but moisture testing every 3 years is recommended. Replace if reading exceeds 3% water content.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

💨

Engine Air Filter

Every 30,000 mi

Replace the engine air filter every 30,000 miles. EcoBoost turbocharged engines are sensitive to airflow restriction — don't extend.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

⚙️

Automatic Transmission Fluid

Every 150,000 mi

Ford 6R80, 10R80, and 8F transmissions use Mercon LV fluid rated 150,000 miles under normal service. Severe service (towing, plowing) drops this to 60,000 miles.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

🔩

Transfer Case Fluid (4WD models)

Every 60,000 mi

F-150 4x4 and Bronco 4x4: replace transfer case fluid every 60,000 miles. Use Motorcraft XL-12 — do not substitute generic transfer case fluid.

Estimated cost — typical U.S. ranges

Dealer

~$105–$140

Shop

~$75–$100

DIY

~$15–$40

AWD/4WD vehicles only. Easy drain-and-fill on most platforms.

🔧

Rear Differential Fluid

Every 100,000 mi

F-Series and Expedition: replace rear axle fluid every 100,000 miles, or 50,000 miles if towing. Limited-slip rear ends require friction-modifier additive.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.

Spark Plugs

Every 100,000 mi

Iridium spark plugs on Coyote 5.0L, EcoBoost 2.7L/3.5L, and 2.3L are rated 100,000 miles. EcoBoost engines: never exceed the interval — gap erosion causes coil failure.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

🌡️

Engine Coolant

Every 50,000 mi

Motorcraft Orange (Dex-Cool compatible) coolant: first change at 100,000 miles, then every 50,000. Older trucks with Yellow Motorcraft coolant: 50,000 miles throughout.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Recommended maintenance

Extends the life of your vehicle and improves comfort

🌬️

Cabin Air Filter

Every 20,000 mi

Replace the cabin air filter every 20,000 miles. On F-150, located behind the glove box; on Escape and Explorer, accessed from the passenger footwell.

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
