Detailed Description

This Dorman thermostat housing assembly, part number 902-681, is engineered to match the original housing layout on select vehicles and to handle repeated temperature cycling in the cooling system. It includes the thermostat and gasket, making it a direct replacement option for service on applications such as the 2012-2015 Ford Edge, 2012-2017 Land Rover Range Rover Evoque, and 2013-2015 Jaguar XF.

Installation Notes and Tips

Verify the vehicle’s year, make, model, and engine cooling configuration before installation. Clean the mating surfaces thoroughly, inspect adjacent hoses and clamps, and transfer only the components required by the application. Because mounting hardware is not included, reuse or source the correct fasteners as needed. Confirm proper coolant fill and bleed procedure after installation to help restore normal operating temperature.

Quality Assurance

Dorman designs this thermostat housing assembly to match stock fit and durability expectations for the listed applications. The housing is built to withstand extreme temperature changes, helping support long service life in demanding cooling system conditions.
