⚙️ Key Features

• Thermostat housing to heat exchanger
• 0.018 kg
• 60 applications across TAMD, AD, D, TMD, KAD and KAMD engines

🔌 Function

Forms the coolant connection between the thermostat housing and the heat exchanger, providing the threaded or spigot seat the joint seals against.

⚠️ Common Signs of Failure

• Coolant weep at the thermostat housing joint
• Coolant salt crust building at the adapter shoulder
• Thread or sealing seat corroded or damaged
• Adapter loose in the housing so it will not seal

🛠️ Service Notes

• Renew the sealing ring or gasket at the same time and clean both seats before assembly
• Do not overtighten into an alloy housing; the seal does the work, not the thread

📦 Condition

• Genuine Volvo Penta part
