Detailed Description

The Motorad 4820KT thermostat housing assembly is engineered for classic Chevrolet cooling system repair where accurate temperature regulation matters. It is listed for 1955-1967 Chevrolet Bel Air, 1959-1961 Chevrolet Impala, 1956-1957 Chevrolet Corvette, and 1967 Chevrolet C10 Suburban, C20 Suburban, K10 Suburban, and K20 Suburban applications with notes calling for a 195F thermostat in several listings. This part number, 4820KT, is also referenced for the same application under cross-reference number 94820KT.

Built with OEM specifications in mind, the housing uses a copper thermostat element and OE-style sealing surfaces to help maintain proper coolant flow and temperature control. The offset design and air relief valve, where applicable, support serviceability in original-equipment-style cooling layouts.

What It Helps Address

• Coolant temperature that stays too low or too high
• Leaking thermostat housing or degraded sealing surfaces
• Cooling system service on original-style Chevrolet engines
• Temperature control concerns in restored or maintained classic vehicles
• Replacement of worn thermostat housing assemblies during cooling repairs

Installation Notes and Tips

Verify engine application and thermostat temperature specification before installation. Clean the mating surfaces thoroughly, inspect the coolant passages, and confirm the gasket seats evenly against the housing. Use the correct torque sequence for the two-bolt housing and refill the cooling system with the proper coolant mixture after installation. This part is listed for compatible Chevrolet Bel Air, Impala, Corvette, and select 1967 Suburban applications, so confirm the exact engine configuration against the vehicle’s cooling system layout.
