11033572 Restrictor | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta cooling system restriction, the outgoing flow variant, used to meter and balance coolant flow within the engine's cooling circuit. Its outgoing-flow designation is what separates it from other restrictions sharing the same name, so confirm the flow direction required for your engine before ordering. It is a small, lightweight precision component fitted across a broad span of Volvo Penta marine, genset and industrial diesel engines.

🚤 Compatibility

• Engine Family: D, TAD, TAMD, TWD, TID, TD, TADH
• Year Range: Approximately 1980s onward, engine and cooling-package controlled

🔌 Function

The restriction sets a calibrated flow area in the cooling circuit so coolant is distributed at the correct rate and pressure between engine sections. Correct restriction sizing maintains stable operating temperature and prevents localised overheating or excessive flow bypass.

⚠️ Common Signs of Failure

• Engine running hotter than normal or fluctuating coolant temperature
• Blockage from scale, corrosion debris or casting residue reducing coolant flow
• Erosion or wear enlarging the metered opening, upsetting cooling balance
• Coolant seepage or leakage at the restriction's seating location
• Uneven cooling between cylinders or between engine and heat exchanger circuits

🛠️ Service Notes

• Check the restrictor's metering orifice is free of scale, corrosion debris or casting residue before fitting — a partially blocked or worn opening will not restore correct flow balance even if the part otherwise looks right
• Fit with a new gasket or O-ring at the housing if one is used there, rather than reusing a compressed seal
• After fitting, run the engine to operating temperature and check for even warming across the cooling circuits, watching for the hot-running or fluctuating-temperature symptoms this part is meant to prevent
• Because several restrictions share this name across the engine range, keep the removed restrictor for comparison until the new one is confirmed to seat and fit correctly
