3804752 EGR Cooler Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for an egr cooler. It is the refundable charge raised against the old egr cooler when the exchange unit is bought, and it comes back once the worn egr cooler is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3801752, which is the number to quote for the component itself. The other egr cooler core running through this block is 3804751, and nothing published against them separates one from another, so order the number that matches the egr cooler actually coming off.

⚙️ Key Features

• Core deposit line, not an egr cooler you can fit
• Belongs with the exchange unit, part number 3801752
• Refunded when the old egr cooler is returned
• Not separable from the other egr cooler cores here, so order by part number

🔌 Function

As a line item it carries the refundable core charge on the exchange; the cooler itself takes the exhaust gas being recirculated back to the inlet and drops its temperature through a coolant-fed core, so the charge going back in does its job without pushing combustion temperatures up.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the egr cooler being exchanged
• Coolant level falling with no external leak, and white smoke or steam at the exhaust
• Header tank pressurising or bubbling once the engine is warm
• Power down with heavy sooting, or an exhaust gas recirculation fault reported at the display
• On strip-down, a core blocked with soot, corroded or split tubes and coolant staining inside the gas passages

🛠️ Service Notes

• The charge is refunded when the worn egr cooler is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3801752
• Check the recirculation valve and the pipework for soot blockage at the same time, since a restricted circuit is what cooks the cooler and will do it again

📦 Condition

• Refundable core deposit - not a physical part
