21839586 Cover | Genuine Volvo Penta Part

🔧 Product Description

Oil-cooler cover for the TAD1180-TAD1183 lubrication system. It closes the cooler housing, supports the sealing joint and directs engine oil through the cooler core.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD1180-83VE

• Engine Family: TAD

⚙️ Key Features

• Factory oil-cooler housing profile
• Machined sealing face
• Maintains internal oil routing
• Used on TAD1180-TAD1183 engines
• Direct replacement cover
• Engine type: 6-cylinder turbocharged industrial diesel

🔌 Function

Retains and seals the oil-cooler core so pressurised engine oil is routed through the heat exchanger without external leakage or internal bypass.

⚠️ Common Signs of Failure

• Oil leakage at the cover joint
• Warped or damaged sealing face
• Oil/coolant cross-contamination where the cooler assembly is compromised
• Low oil pressure after housing damage

🛠️ Service Notes

• Clean both sealing faces back to clean metal and check the cover for distortion, cracks or pulled bolt holes before refitting — a warped flange will not seal even with a new gasket
• Where the joint uses a gasket, seal or O-ring, always fit a new one and seat it dry unless the workshop manual for your engine specifies a sealant; never try to make a poor joint tight with extra sealant
• Tighten the fasteners progressively and evenly, working out from the centre, to the figure given in the manual for your engine — pressed steel, alloy and plastic covers distort easily if pulled down hard or unevenly
• If the cover carries a shaft seal or bearing, support it square to the shaft as it goes on so the seal lip is not nicked or rolled over
• Check that any breather, drain or oil return passage in the cover is clear before final tightening, and look for leaks once the engine has been run up to temperature
