Endeavor V6-3.8L SOHC (2004)
Using a valve core made of different metal than the valve stem can lead to corrosion. Genuine Mitsubishi valve core replacements are available through
the spare parts channel. Refer to CAPS for the correct part number for your vehicle.
Be careful when installing a valve core. The aluminum stem is easily broken if overtightened. Torque the valve core to 0.25NM / 2.5 in/lb.
Torque sensing valve core tightening tools are available from several manufactures, including Snap On and KD Tools. Some manufactures offer them
calibrated to different settings. When purchasing, make sure you get one that meets the torque spec (0.25NM / 2.5 in/lb).
