21663749 Fan Shroud | Genuine Volvo Penta Part

🔧 Product Description

A left-hand fan-shroud section used in the EDC4 radiator and charge-air-cooler package of Volvo Penta TAD732GE and TAD733GE engines.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD732GE EDC4
• Volvo Penta TAD733GE EDC4

• Engine Family: TAD

⚙️ Key Features

• Left fan-shroud section
• EDC4 generating-set cooling package
• Directs fan airflow through radiator and intercooler
• Works with the right grille and mounting brackets

🔌 Function

The shroud controls airflow through the cooling cores and guards the rotating fan.

⚠️ Common Signs of Failure

• Fan contact with the shroud
• Cracks or broken mounting points
• Reduced cooling airflow
• Rattling or vibration
• Debris accumulation

🛠️ Service Notes

• Fit the shroud before the fan wherever access allows, then turn the engine over by hand and check the blade tips clear the shroud all the way round through a full revolution
• Make sure the shroud seals against the radiator or cooler face and that any foam strip, seal or grommet is present and sound — air drawn round the outside of the core instead of through it will cost cooling
• Use the rubber grommets, spacers and mounts supplied for the joint; mounting a plastic shroud hard against metal cracks it around the fixing points
• Tighten the fixings only enough to hold the shroud flat and square — moulded and thin sheet shrouds distort and crack if pulled down hard
• Check the shroud for cracks, missing corners and previous makeshift repairs while it is off, and clear leaves, weed and debris from the core behind it before refitting
