To burp a radiator, cool the system, loosen the bleed valve until air hisses out, then close it when a steady stream of coolant flows.

To buff out scratches on a car, clean the area, check the depth, then work a mild compound with a pad in short, even passes.

Power steering bleeding means cycling the wheel while topping up fluid so trapped air escapes and the steering feels smooth again.

Bleeding brakes by yourself uses a one person method, fresh fluid, and the right wheel order so air leaves the system and the pedal feels solid.

To bleed brake lines, push fresh fluid through each brake until clear, bubble-free fluid flows and the pedal feels firm.

To bleed a master cylinder, bench-bleed it level, then push fluid through until no air bubbles remain and the brake pedal feels firm.

To bleed a cooling system, purge trapped air with a careful warm-up and coolant top-up until only liquid flows.

To bleed a clutch, open the bleeder, pump the pedal with fresh fluid, then close the valve when only clear, bubble-free fluid flows.

To bench bleed a master cylinder, clamp it in a vise, fit bleed tubes, then slowly stroke the piston until no air bubbles appear in the brake fluid.

To balance tires, a technician adjusts small wheel weights so each tire spins smoothly without vibration at driving speed.
