How to Replace a Tire Valve Core

Replacing tire valve cores is simple enough and only takes a few seconds once the tire is off the vehicle. However, if the tire is on the vehicle, supporting the vehicle on a jack stand or stands is advised to avoid damaging the rim or tire under the weight of the vehicle. In addition, tire pressure monitoring systems equipped in cars manufactured in 2007 and later must use nickel-plated valve cores to prevent corrosion from occurring to the indirect sensor.

Skill level:

Things you need

  • Valve core removal tool
  • Replacement valve cores (nickel-plated for TPMS sensors)
  • Torquing valve core tool (for TPMS sensors)
  • Air compressor
  • Tire gauge
  • Spray bottle with soapy water

  1. 1

    Remove the valve stem cap by turning it counterclockwise.

  2. 2

    Align the valve core removal tool onto the head of the valve core. Turn the valve core tool counterclockwise (with the vehicle supported if the tire is still on the vehicle) until it unscrews from the valve stem.

  3. 3

    Inspect the valve core hole and ensure there is no debris or corrosion present. If there is, blow it out with an air compressor.

  4. 4

    Insert the new valve core into the valve stem and tighten it with the valve core removal tool or a torquing valve core tool for TPMS tires. Tighten the valve core snugly or until the torquing tool clicks.

  5. 5

    Inflate the tire to the recommended tire pressure for the vehicle printed on the tire placard (located on the driver's side door jamb) with the air compressor. If the compressor is not equipped with a pressure gauge, use a tire pressure gauge to monitor the tire pressure until it reaches the recommended level.

  6. 6

    Spray the valve stem and core with soapy water to inspect it and ensure it is not leaking.

  7. 7

    Replace the valve stem cap.
