3801625 Turbocharger Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured turbocharger from the Inlet and Exhaust System group, weighing 30.84 kg and listed for 2 applications across the TAD series. In the reman tables it is the turbocharger listed with long block 3801688 built without VCB, cylinder head 3801804 and unit injector 3801652. It sits between 3801677 at 31.26 kg and the 34.02 kg unit 3801669, close enough that the number is the only safe guide. Reman turbochargers are stripped to the core, restored to what is technically new condition with wear parts replaced by new genuine parts, brought up to the latest technical specification and tested before being painted. It is supplied on an exchange basis: core deposit 3804625 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

⚠️ Common Signs of Failure

• Boost falling away with black smoke on acceleration
• Whining or a metallic rattle from the turbo
• Oil in the inlet or exhaust pipework
• Oil consumption rising with no external leak

🛠️ Service Notes

• 3801677 is only 420 grams heavier and also a single-application TAD turbo, so weight is not a safe way to choose - order by number
• Prime the new turbo with clean oil and crank on the starter with the fuel off before firing up
• The old turbocharger returns as the core once the new one is fitted and the engine is running, releasing deposit 3804625
