22203754 Wastegate Actuator | Genuine Volvo Penta Part

🔧 Product Description

Calibrated turbocharger wastegate actuator used on the front turbocharger of D13B-A MP engines from the documented serial break. It converts boost/control pressure into wastegate movement to regulate turbocharger speed and manifold pressure.

⚙️ Key Features

• Factory-calibrated actuator spring and travel
• Matched mounting bracket and wastegate lever geometry
• Controls boost and turbocharger overspeed
• Designed for high under-cowl temperature and vibration
• Actuator setting must not be altered without the specified procedure

🔌 Function

Controls wastegate opening to maintain commanded boost pressure and protect the turbocharger/engine from overboost.

⚠️ Common Signs of Failure

• Low boost, smoke or loss of power from an actuator stuck open
• Overboost, high exhaust temperature or protection derate from an actuator stuck closed
• Cracked diaphragm or pressure leakage
• Seized linkage or incorrect rod adjustment
• Rattle, uneven boost or diagnostic faults

🛠️ Service Notes

• This actuator fits only the front of the two turbochargers on these D13B/D13C engines and is tied to a documented engine serial-number break - confirm both turbo position and engine serial before ordering, since the rear-turbo actuator is a separate part
