Installation Notes and Tips

Verify the outlet diameter, mounting hole count, and neck angle before installation. Transfer only the components required for your application, and replace the sealing surfaces as needed to help prevent leaks. Because the thermostat is not included, confirm whether your repair requires reuse of the existing thermostat or separate replacement. This housing is listed for 2005-2010 Chrysler 300, 2006-2010 Dodge Charger, and 2005-2008 Dodge Magnum cooling system applications.
