21202084 Heat Exchanger | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta complete heat exchanger used in the cooling system identified by part number 21202084. The approximately 25 kg assembly transfers heat from the closed engine-coolant circuit to the raw-water or secondary cooling circuit and must be selected by exact product specification because adjacent 21202086 and 21202089 units are different assemblies.

⚙️ Key Features

• Genuine Volvo Penta complete heat exchanger
• 25 kg
• Heavy-duty marine or stationary cooling construction
• Separate assembly from heat exchangers 21202086 and 21202089
• Match end covers, connection positions and engine product number
• Engine type: Volvo Penta heavy-duty diesel with closed-circuit heat-exchanger cooling

🔌 Function

Transfers engine heat across separated coolant and cooling-water circuits without mixing the fluids.

⚠️ Common Signs of Failure

• Engine temperature rising at sustained load
• Coolant or seawater cross-leakage
• Restricted tubes caused by scale, debris or marine growth
• External corrosion, pitting or leakage at end covers
• Reduced heat transfer despite normal pump operation

🛠️ Service Notes

• Heat exchangers 21202086 and 21202089 are separate assemblies at 21.183 kg and 45.358 kg, so check the product number rather than assuming interchange
