3801798 Turbocharger Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured turbocharger for the D4 G-series, weighing 13.485 kg and listed for eleven applications from the D4-145I-G through to the D4-320A-G. It is the heaviest of the three closely matched D4 turbochargers here, but only by 211 grams over 3802150 and 646 grams over 3801173, so the generation and engine rating decide the order rather than the weight. Volvo Penta reman turbochargers are rebuilt to the current bill of material, tested to verify performance and painted before despatch. Supplied on exchange, so a core fee is added to the invoice and refunded once the worn unit is returned.

🔌 Function

Uses exhaust energy to drive a compressor wheel, forcing more air into the cylinders so more fuel can be burned for a given engine size.

⚠️ Common Signs of Failure

• Blue smoke on start-up or over-run as oil passes the seals
• A rising siren or whistle that changes with engine speed
• Sluggish acceleration and loss of top-end power
• Oil pooling in the inlet pipe or intercooler
• Visible shaft play or wheel-to-housing contact marks on strip-down

🛠️ Service Notes

• Check against 3802150 and 3801173 before ordering - the three are within 650 grams and only the engine list separates them
• Establish why the old unit failed before fitting this one, because oil starvation and debris in the feed will kill a replacement quickly
• Core deposit 3804798 carries the exchange fee and is refunded when the old turbocharger goes back
