The absolute cornerstone of preservation is a fanatical approach to fluids and corrosion control. Factory service intervals were designed for a vehicle's first decade of life, not its third. Adopt a more aggressive schedule: change engine oil and filter with a high-quality conventional or synthetic blend every 3,000-5,000 miles. Annually flush and replace coolant, using the correct DEX-COOL formula or a full-system-converted traditional antifreeze to prevent intake gasket and heater core issues. Brake fluid is hygroscopic, meaning it absorbs moisture from the air, leading to internal corrosion and a spongy pedal; it should be flushed every two years without exception. Perhaps the most critical, yet most overlooked, defense is undercoarding. Annually, thoroughly clean the truck's undercarriage and apply a fluid film or lanolin-based corrosion inhibitor, paying special attention to the vulnerable rear wheel arches, rocker panels, and frame rails. This single ritual is the most effective action you can take to prevent the terminal rot that claims so many of these trucks.
