Motorad CH1008 Engine Coolant Thermostat Housing - Upper

Engine Coolant Thermostat Housing Overview

The Motorad CH1008 engine coolant thermostat housing is built for cooling-system service where a precise fit and leak control matter. It is an aluminum housing with a silver finish, made to OEM quality standards by an OE supplier and validated for thermal shock and leak resistance.

Fits 2006-2010 Kia Optima, upper; fits 2007-2010 Kia Rondo, upper; fits 2007-2009 Hyundai Santa Fe, upper. The CH1008 is a direct-fit cooling component for applications that use an engine coolant water outlet with housing.

Key Features

• Aluminum construction for a rigid, corrosion-resistant housing.
• Thermal shock validated for demanding cooling-system temperature changes.
• 100% leak tested for sealing confidence before installation.
• Three mounting holes with a 3.25-inch bolt-hole center spacing.
• Single outlet port with 1.39-inch outlet diameter and 1.40-inch inlet diameter.
• No gasket or seal included; no bolts or mounting hardware included.

Detailed Description

Motorad CH1008 is an engine coolant thermostat housing engineered for upper cooling-system service on select Kia and Hyundai applications. The aluminum body and OE-supplier manufacturing standards support consistent fit and function, while the thermal shock validation and leak testing address the stress created by repeated heat cycling. This part number, CH1008, is used in applications such as the Kia Optima, Kia Rondo, and Hyundai Santa Fe where the engine coolant water outlet is integrated with the housing.

The housing features one outlet port, three mounting holes, and a silver finish. Its dimensions and port sizing are important for matching the original cooling layout, especially when replacing a worn or leaking thermostat housing. This part cross-references 256313E000 for the same application.

What It Is Used For

• Replacing a cracked or warped thermostat housing.
• Addressing coolant seepage at the water outlet connection.
• Restoring proper sealing after heat-related housing damage.
• Correcting fitment issues caused by worn mounting surfaces.

Installation Notes and Tips

Verify the upper housing configuration, port diameter, and mounting-hole spacing before installation. Inspect the mating surface and replace any worn seals or gaskets required by the application, since this housing does not include a gasket or seal. Confirm the cooling-system layout against the original part number CH1008 before assembly.

Quality Assurance

Manufactured to OEM quality standards by an OE supplier, this housing is thermal shock validated and 100% leak tested. Motorad CH1008 is built to meet the demands of automotive cooling systems and support reliable sealing in service.
