Detailed Description

Motorad 4899KT is an engine coolant thermostat housing assembly designed for OE-style replacement on many Chevrolet Caprice, Camaro, El Camino, Monte Carlo, Impala, Corvette, Nova, Blazer, C10, K10, and GMC Jimmy and Suburban applications, along with select Buick, Pontiac, and Oldsmobile models. The housing is engineered to match factory specifications, and the thermostat uses a copper case and wax compound to react quickly to coolant temperature changes. This helps maintain the listed 195F operating temperature used in the confirmed fitments.

This part cross-references 94899KT and NI for the same application. The Motorad 4899KT is a practical choice when replacing a worn thermostat housing on vehicles such as Chevrolet Camaro, Caprice, and GMC Jimmy applications that require OE-specified cooling system service.

What It Helps Address

• Coolant leaks at the thermostat housing or gasket surface
• Temperature control issues caused by a worn thermostat
• Corrosion or deterioration in the original housing assembly
• Improper sealing from aged OEM-style gaskets
• Cooling system service on factory 195F applications

Installation Notes and Tips

Verify the engine and cooling system configuration against the listed fitment notes before installation. Clean the mating surfaces thoroughly, inspect the coolant passages for corrosion or debris, and replace coolant as needed during service. Bolts are not included, so reuse or source the correct fasteners for the vehicle. Confirm the housing orientation and any threaded outlet or fitting requirements noted in the application listing.
