Summary

This is a Technical Journal: Coolant Pump Dry Coolant Mix Residue. If the coolant pump has an active leak, a photo must be taken prior to replacement (see example as in attached picture TJ_36923_3). The photo showing the active water pump leak on the vehicle must be saved for the TMA photo return process and provided when requested.
 Sealing improvements have been made to PNs 32382367, 32441161 and 32382368, but the part numbers are unchanged. To assist with identification of improved parts, a marking has been added to the parts: an "X," as shown in the attached document TJ_36923_1.pdf.
 If you receive a replacement pump that does not have the "X" marking, please return it and order a replacement
