Product Details

This Four Seasons Water Outlet, part number 86018, is a direct-fit engine coolant component for vehicles that use an aluminum outlet housing in the cooling circuit. It is designed for applications including 2008-2012 Honda Accord, 2011-2017 Honda Odyssey, 2009-2015 Honda Pilot, 2009-2014 Honda Ridgeline, and select Acura models such as TL, TSX, MDX, ZDX, RL, and RDX.

Four Seasons 86018 is intended for buyers replacing a worn, corroded, or leaking coolant outlet on Honda Odyssey, Honda Pilot, or Acura TL applications while maintaining proper coolant routing.

Common Uses

• Replacing a cracked or corroded coolant outlet housing
• Repairing coolant leaks at the outlet connection
• Restoring proper coolant flow path in the engine cooling system
• Addressing sealing issues caused by worn mating surfaces
• Servicing OE-style cooling components on Honda and Acura vehicles

Installation Notes

Verify the inlet diameter, bolt-hole spacing, and mounting flange dimensions before installation. Because the gasket or seal is not included, transfer or replace the sealing component as required by the application. Inspect the mating surfaces, coolant hoses, and adjacent thermostat housing components for wear before reassembly.
