WARNING: This page is about a different car, the 2008 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: When installing a new seal and seal washer, make sure to support the valve stem base with a thumb so that there is no movement of the stem. Otherwise, the stem may protrude resulting in the breakage of antenna plate.
  1. Insert these up to the base of the TPMS transmitter, making sure to secure the valve base with a thumb, as shown.

    Wipe the seal and threading.
