Please note: Updated versions of this water pump may include a large weep hole on the Oil Cooler Flange, which requires the use of Water Pump Filter #
1085959 (Not included). This additional port allows normal seepage associated with the lubrication and cooling of the water pump seal. If an excessive amount of coolant is leaking from the weep hole and/or discoloration is noticed in the weep hole area, it is typically is indicative of failing internal components. In this instance, water pump service or replacement is required. Rather than replacing the entire water pump, a water pump repair kit can is offered.
