Essential Fluids and Filters

  • Engine Oil and Filter: Regular oil changes are vital for engine health. The oil cleans and lubricates moving parts, and the filter traps contaminants. Follow the manufacturer’s recommended intervals for oil changes.
  • Air Filter: A clean air filter ensures your engine gets the clean air it needs for efficient operation. Dirty air filters can reduce fuel economy and engine power.
  • Transmission Fluid: The transmission fluid lubricates and cools the transmission components. Check the fluid level and condition regularly, and change it according to the manufacturer’s recommendations.
  • Other Fluids: Check and top off other fluids like brake fluid, power steering fluid, and coolant as needed.

Lights and Electrical Systems

  • Lights: Inspect all headlights, taillights, brake lights, turn signals, and reverse lights regularly. Ensure they are working properly and replace any burned-out bulbs.
  • Battery: The battery provides the electrical power to start your truck. Check the battery terminals for corrosion and clean them if necessary. Visually inspect the battery for cracks or leaks.


  • Brake Pads and Rotors: The brakes are critical for safety. Visually inspect the brake pads for wear and tear. If they are nearing the end of their lifespan, replace them promptly.
  • Brake Fluid: Brake fluid transmits pressure from the brake pedal to the wheels. Check the fluid level and condition regularly.

Tires and Wheels

  • Tire Pressure and Tread Depth: Proper tire pressure improves fuel efficiency, handling, and tread life. Check the tire pressure regularly, including the spare tire. Inspect the tread depth for wear and replace tires when they reach the wear bars.
  • Wheel Alignment: Proper wheel alignment ensures the tires wear evenly and prevents premature tire wear.

Engine and Drivetrain

  • Engine Belts and Hoses: Visually inspect the belts and hoses for cracks, wear, or loose connections. Replace any damaged belts or hoses.
  • Engine Mounts: The engine mounts support the engine and transmission. Inspect the mounts for signs of wear or damage.

Other Checks

  • Windshield Wipers and Wiper Fluid: Ensure the windshield wipers are in good condition and the wiper fluid reservoir is full.
  • Steering and Suspension: Check the steering for any looseness or play. Inspect the suspension components for signs of wear or damage.
  • Exhaust System: Look for any leaks, cracks, or rust in the exhaust system.
  • Interior: Check the horn, seat belts, and gauges for proper operation.
