⚙️ Key Features

• 4.357 kg
• 37 applications across TD, TWD, TID and TAD engines
• Cooling System group casting

🔌 Function

Houses the thermostat and directs coolant either back through the bypass or out to the cooler as the engine warms.

⚠️ Common Signs of Failure

• Coolant seeping from the housing joint or from a porous casting
• Engine slow to warm, or overheating with a thermostat that tests good
• Corrosion pitting and scale build-up inside the bores
• Stripped or pulled fixing threads in the casting
• Thermostat seat eroded so the valve no longer seals

🛠️ Service Notes

• Housing 470548 at 4.146 kg is the TMD and TAMD version - the two are close in weight, so order by engine series rather than by size
• Renew the housing gasket and the thermostat at the same time, and check the mating face on the head for flatness

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
