Case 355239A1 Thermostat Housing Assembly

The Case 355239A1 thermostat housing assembly regulates engine coolant flow in Case construction equipment. Manufactured to OEM specifications, this housing integrates the thermostat mounting flange and coolant inlet/outlet ports. It is designed for direct installation on Case 9007B, CX75SR, and CX80 crawler excavators. Installation requires mounting bolts (M8x30 and M8x70 per OEM parts diagram) and a sealing plug (part 355240A1). The housing accommodates the engine thermostat and coolant temperature sensor. This part supersedes earlier revisions and serves as a direct replacement for OEM numbers 72961604 and VI894428-8120. Constructed from high-strength aluminum alloy for thermal conductivity and corrosion resistance in heavy-duty cooling systems.
