Fluid Checks and Changes

Fluids are the lifeblood of your truck. Regularly checking and changing them is non-negotiable.

  • Engine Oil: Check your oil level weekly and follow Ford’s recommended intervals for oil and filter changes. For most 2015 models, this is typically every 5,000-10,000 miles, depending on the oil type and driving conditions. Use the correct synthetic or synthetic blend oil specified in your owner’s manual.
  • Transmission Fluid: While many modern transmissions are “sealed for life,” it’s wise to inspect the fluid level and condition periodically. If you tow heavily or drive in extreme conditions, consider a fluid and filter change around 60,000-100,000 miles. Always use Ford-approved MERCON LV fluid.
  • Coolant: Maintain the proper coolant level and concentration (typically a 50/50 mix of distilled water and concentrated coolant). Flush and replace your coolant every 100,000 miles or as recommended. This prevents overheating and protects against corrosion.
  • Brake Fluid: Check the brake fluid level and color. Dark or cloudy fluid indicates contamination and warrants a flush. This should be done every 2-3 years to maintain optimal braking performance.
  • Power Steering Fluid: For models with hydraulic power steering, check the reservoir. Low levels or dark fluid can indicate a leak or contamination. Many F-150s of this generation use electric power steering, which does not require fluid checks.

Tire Care and Inspection

Your tires are your only contact with the road, making their condition critical for safety and performance.

  • Tire Pressure: Check tire pressure weekly, especially before long trips or heavy loads. Proper inflation improves fuel economy, extends tire life, and ensures stable handling. The recommended pressure is typically found on a sticker inside the driver’s door jamb.
  • Tire Rotation: Rotate your tires every 5,000-7,500 miles. This promotes even wear across all four tires, maximizing their lifespan. An uneven wear pattern can indicate alignment issues or worn suspension components.
  • Tread Depth: Inspect tread depth regularly using a tire tread depth gauge or the “penny test.” Replace tires when tread depth reaches 4/32″ (front) or 2/32″ (rear) for optimal safety, especially in wet conditions.

Brake System Maintenance

Functional brakes are paramount for safety. Don’t neglect them.

  • Brake Pad and Rotor Inspection: Visually inspect brake pads and rotors every oil change. Look for uneven wear, deep grooves on rotors, or pads worn down to the wear indicators. Replace components as needed.
  • Brake Line Check: Periodically check brake lines for rust, leaks, or damage. A soft or spongy brake pedal often indicates air in the lines or a fluid leak.
