Product Details

Four Seasons Water Outlet 85975 is part of the brand’s Water Outlet line within engine coolant components. This housing is used in cooling system service where the coolant outlet needs to be replaced with an OE-style aluminum part.

• Cooling system service on Honda Civic, Acura ILX, or Honda HR-V
• Replacement of an outlet housing that no longer seals properly

Installation Notes

Verify the inlet diameter, bolt spacing, and mounting flange dimensions against the original part before installation. Because the gasket or seal is not included, transfer or source the correct sealing component separately. Confirm whether the vehicle uses an upper outlet or outlet-style housing, and match the application to the exact year, make, and model listed for Four Seasons 85975.
