⚙️ Key Features

• Thermostat
• 0.078 kg
• Listed for 30 D series applications

🔌 Function

Opens and closes the path to the heat exchanger as coolant temperature changes, holding the engine at its designed running temperature rather than letting it run cold or overheat.

⚠️ Common Signs of Failure

• Engine slow to reach temperature, or never reaching it, when the thermostat sticks open
• Rapid overheating from cold when it sticks shut
• Temperature gauge swinging up and down in normal running
• Sooty exhaust and poor economy from persistent under-cooling
• Element found corroded, or the seal perished, when the housing is opened

🛠️ Service Notes

• Renew the housing gasket or seal with the thermostat
• Fit it the right way round with the sensing element toward the engine, and bleed the circuit fully after refilling
• Check the heat exchanger, impeller and coolant level before blaming the thermostat for overheating

📦 Condition

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