Product Details

This Four Seasons Water Outlet line part is intended for engine coolant routing where the original outlet has worn, corroded, or leaked. The steel housing is specified as a thermostat-free outlet, and the design does not include a gasket or seal or a bleeder screw. For buyers searching for an Infiniti Q45 water outlet, coolant outlet housing, or engine coolant components replacement, part number 86186 provides a direct-fit service option for the listed vehicle application. This part cross-references Dorman - Conduct-Tite 86186 for the same application.

Common Cooling System Issues It Can Address

  • Coolant seepage at the outlet housing
  • Corrosion or pitting in the original steel outlet
  • Cracked or warped coolant outlet flange
  • Improper coolant routing from a damaged outlet
  • Service replacement for a thermostatless water outlet assembly

Installation Notes and Tips

Verify the inlet diameter, bolt-hole spacing, and mounting-hole count against the original part before installation. Because the gasket or seal is not included, reuse only if serviceable or source the correct sealing component separately. Confirm the thermostat configuration matches the vehicle’s original setup, since this outlet is supplied without a thermostat and without a bleeder screw.

Quality Assurance

Four Seasons lists this water outlet as meeting or exceeding OEM requirements. It is built as an OE-style replacement for the specified Infiniti Q45 cooling system application and is identified under part number 86186.
