Oil Service: A Condition-Based Checklist
An oil service includes correct specification and quantity, filter and sealing parts, leak inspection, level verification, service reset, and a record of operating conditions.
Category Maintenance
Condition-based maintenance guides for fluids, tires, brakes, batteries, filters, and inspections.
Brake Fluid Inspection: More Than Color
Fluid appearance alone does not establish moisture content, boiling performance, contamination, service interval, or hydraulic component condition.
Coolant Service: Compatibility and Air Bleeding
Coolant color is not a reliable specification. Chemistry, concentration, water quality, fill method, and air bleeding affect corrosion protection and temperature control.
Tire Rotation: Record the Wear Pattern First
Rotation can even normal wear, but it should not hide an alignment, pressure, suspension, damage, or directional-tire issue.
Seasonal 12-Volt Battery and Charging Check
Temperature extremes expose low state of charge, reduced capacity, poor connections, and marginal charging performance.
