Product Details

This Motorad thermostat housing, part number CH1066, is engineered as a direct replacement-style coolant outlet housing for lower-position applications. It is listed for 2005-2015 Toyota Tacoma, lower; 2007-2014 Toyota FJ Cruiser, lower; 2006-2009 Toyota 4Runner, lower; and 2003-2005 Toyota 4Runner, lower.

Installation Notes

Verify lower-position fitment before installation and compare the port diameters, mounting-hole layout, and flange dimensions to the original part. Gasket or seal is not included, and bolts are not included, so reuse or source the required sealing components separately as needed for the application.
