22412938 Drain Valve | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta service drain valve used in selected engine cooling or fluid-drain arrangements. The valve provides a controlled low-point outlet for maintenance, coolant replacement or winterisation without requiring a hose or pipe connection to be removed. Its thread, sealing form and installation location are application-specific.

⚙️ Key Features

• Genuine Volvo Penta service-drain component
• Provides controlled opening and closure of a low-point drain
• Reduces spillage during scheduled fluid servicing
• Correct thread and sealing geometry for the matched housing or pipe
• Suitable for repeated workshop drain operations when maintained correctly
• Application and fluid circuit must be confirmed before installation
• Engine type: Volvo Penta marine or industrial diesel cooling/service system

🔌 Function

Opens a controlled path from a low point in the fluid circuit so coolant or another specified service fluid can be drained, then seals the circuit again for normal operation.

⚠️ Common Signs of Failure

• Fluid seepage with the valve closed
• Valve seized open or closed
• Damaged operating head or threads
• Incomplete or very slow draining
• Corrosion or mineral deposits at the outlet
• Air entering the cooling circuit through a damaged seal

🛠️ Service Notes

• Establish what the valve seals against, then drain and depressurise that system before removing it so nothing is lost or spilled into the bilge
• Clean the threads and the sealing face in the housing, fit a new sealing washer or O-ring where one is used, and seal a tapered thread with the product the manual specifies
• Tighten to the figure in the manual while holding the body so the outlet finishes pointing where it needs to for draining, and take particular care in an alloy or plastic housing
• Work the valve fully open and fully shut by hand to check it moves freely and seats, and refit any cap, plug or drain hose the original carried
• Make sure the valve is fully closed and capped before refilling, then run the system and check it for weeps — a drain left cracked open is an easy way to lose coolant or oil at sea
