How to Replace a Tire Valve Core
- 1). Remove the valve stem cap by turning it counterclockwise.
- 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). 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). 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). 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). Spray the valve stem and core with soapy water to inspect it and ensure it is not leaking.
- 7). Replace the valve stem cap.
