3803637 Unit Injector Reman | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured unit injector weighing 1.211 kg and listed for eight applications across the D and TAD series, the widest fitment of the three closely matched unit injectors here. The reman catalogue lists this number as the injector/unit injector for the D16C-A, D16C-B and D16C-C MH engines, alongside cylinder head 3801605 and turbocharger 3801381. 3803638 at 1.197 kg and 3803917 at 1.220 kg sit within 24 grams of it, so weight separates nothing. This unit is supplied on an exchange basis: core deposit 3806637 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

Combines the high-pressure pumping element, the metering control and the nozzle in one body, delivering fuel directly into the cylinder at the pressure and timing the engine's control system commands.

⚠️ Common Signs of Failure

• Rough running or a misfire traced to one cylinder
• Hard starting with white smoke until the engine warms
• Knock or a sharp rattle from one cylinder under load
• Fuel in the engine oil, or the oil level rising
• Injector-specific faults logged by the engine management

🛠️ Service Notes

• Renew the copper sealing washer and the O-rings, and reset the clamp torque to the engine's figure
• Prove the low-pressure feed and the return line before condemning an injector, and check 3803638 and 3803917 against the engine's own list
• Reman parts are core-based: the core fee is refunded when the worn injector goes back, and the programme lets you return it once the new one is fitted and the engine is running again
