Description

Overview

Thermostat Housing Gasket Yanmar 482 486 Thermo King seals the thermostat case joint on selected Thermo King units that use Yanmar 482, 482E, 486, 486E and 486V engines. When the housing is opened for thermostat or coolant-side service, this gasket is the sealing layer that sits between the case faces. Because that joint is usually disturbed during removal, fitting a fresh gasket helps restore a clean seal on reassembly.

Features

• Matches the thermostat case and housing joint on selected Yanmar-based Thermo King engines
• Covers Yanmar 4TNE84 and 4TNE88 family applications, including 482, 482E, 486, 486E and 486V
• Used when the thermostat housing has been separated for service or leak repair
• Often replaced alongside nearby cooling-side seals when the front assembly is already apart

Compliance and Safety

Clean both sealing faces fully before fitting the new gasket, then check for old material, corrosion or raised edges that can stop the housing from sitting flat. If the cooling system has been opened, refill and bleed it correctly after reassembly. Then run the engine to temperature and inspect the thermostat case for seepage.

Trailer Applications

Thermostat Housing Gasket Yanmar 482 486 Thermo King is used when coolant seepage appears around the thermostat case or when the housing has been opened for thermostat work on reefer engines. On some 486V jobs, the water pump O-ring and pump joint are also checked at the same time because the front cooling assembly is already apart.
