21499476 Valve | Genuine Volvo Penta Part

🔧 Product Description

OEM valve used in Volvo Penta Clear Wake Exhaust System (CWES) installations on compatible IPS-powered vessels. It supersedes earlier valve 21495547 and controls the designed exhaust-system flow or drainage function within the CWES assembly. The valve is also associated with later exhaust-valve service kit 24210710, but part number 21499476 identifies the individual valve rather than the complete kit.

🔌 Function

Controls the specified exhaust-flow or drainage path within the Clear Wake Exhaust System, supporting proper exhaust routing and reducing soot or smoke discharge around the vessel.

⚠️ Common Signs of Failure

• Exhaust or fluid leakage around the valve
• Heavy soot deposits at the valve or nearby joints
• CWES warning or system fault
• Valve sticking because of corrosion or carbon build-up
• Abnormal exhaust noise or poor CWES operation
• Damaged actuator or valve body

🛠️ Service Notes

• Work clean — a valve is a precision component, and dirt or swarf carried in on the sealing faces is the commonest reason a new one fails early
• Fit new sealing rings, gaskets or washers wherever the original used them rather than reusing the old ones, and lubricate them lightly so they seat without rolling or nipping
• Check the seat, bore or housing the valve fits into for corrosion, scoring or distortion; a valve only seals as well as the face it beds on
• Tighten fixings and threaded connections to the figures and in the order given in the workshop manual for your engine — a valve body is easily distorted by overtightening
• After fitting, bleed or refill the system as required, then run the engine and check the valve for leaks and for correct operation before the boat is used
