21099784 Oil Cooler | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Oil Cooler - Part Number: 21099784

A genuine Volvo Penta engine-oil cooler and integrated oil-filter housing service assembly used on TAD620VE, TAD650VE and TAD660VE industrial engines. Engine coolant passes through the cooler body to remove heat from the lubricating oil before the oil is distributed to the bearings, pistons and turbocharger. The housing also incorporates oil-filter and pressure-control passages, so internal cleanliness and correct valve-component installation are critical.

⚙️ Key Features

• Integrated oil-cooler and oil-filter housing assembly

• Coolant-to-oil heat exchanger stabilises lubricant temperature under sustained load

• Internal galleries route filtered oil to the engine lubrication circuit

• Machined bores accommodate the pressure-control valve, plunger, spring and sleeve

• Current service part superseding oil cooler 20914910

🔌 Function

Transfers heat from the engine oil to the coolant and forms the distribution housing for filtered, pressure-regulated lubricating oil. Stable oil temperature preserves viscosity, bearing-film strength and turbocharger lubrication.

Common signs of failure:

• Oil appearing in the coolant or coolant contaminating the engine oil

• External oil or coolant leakage at the cooler housing

• Engine-oil temperature above normal under load

• Low or unstable oil pressure caused by internal valve or gallery faults

• Accelerated bearing or turbocharger wear following oil overheating
