Detailed Description

Motorad 5170KT is an OE-supplier thermostat housing assembly manufactured to OEM specifications and processes. The copper case and wax compound are used to react quickly to coolant temperature changes, helping the thermostat regulate engine operating temperature with consistent response. This part cross-references 95170KT and NI for the same application. It is a direct-fit service part for many Chevrolet Express, Astro, Blazer, S10, and GMC Savana, Safari, Sonoma, and Jimmy applications, including several right-hand-drive export configurations.

What It Helps Address

• Coolant temperature that is not reaching the specified 195°F operating range
• Cracked or worn thermostat housing service needs
• Temperature fluctuation caused by aging thermostat components
• Cooling system sealing issues at the housing interface
• OE replacement needs on Chevrolet and GMC cooling systems

Installation Notes and Tips

Verify engine application, model year, and OE temperature specification before installation. This assembly uses a two-bolt housing design and does not list a gasket or seal as included in the attributes, so confirm the required sealing components for your specific vehicle before service. Clean the mating surfaces thoroughly and inspect the cooling system for contamination or corrosion before reassembly.
