Volvo Penta 21114522 is a genuine OEM engine cooling / manifold water drain plug used on selected Volvo Penta marine engines. Current dealer listings identify 21114522 as a drain plug, and multiple current sources describe it as the blue nylon plug assembly used for draining cooling water during service and winterization.
This plug is commonly sold as an assembly that includes the plug, O-ring, and retaining strap/keeper, which helps keep the plug attached during service so it is less likely to be misplaced in the bilge. Current market references also show 21114522 as the active replacement for earlier Volvo Penta numbers 3849500 and 3849892.

Because published compatibility varies by listing, fitment should still be confirmed by engine serial number and the exact cooling/manifold drain location being serviced. Volvo Penta’s official parts guidance is to identify the exact engine, shield, or drive when selecting replacement parts.
Serial Number Fitment Notice
Fitment should always be confirmed by engine serial number before ordering. Volvo Penta’s official parts shop specifically directs users to identify the exact engine, shield, or drive to locate the correct replacement part.
When This Part Needs Replacement
Replace this drain plug when:
- the original plug is cracked, worn, or damaged
- the O-ring no longer seals reliably
- the retaining strap is broken or missing
- cooling-system draining or winterization service shows the old plug no longer meets reuse condition.
Installation Notes
- Confirm fitment by serial number first.
- Inspect the O-ring and seating surface during installation.
- This part is commonly used for engine and manifold water draining, so it is a smart replacement when servicing cooling drain points before off-season storage or recommissioning.
- Current listings describe it as a complete assembly rather than a bare plug alone.

Parts Desk Insight
This is a small part, but it matters. Drain plugs are easy to overlook until one starts leaking or disappears during service. The keeper-style strap is one of the best parts of this design because it helps prevent a simple drain-plug job from turning into a parts hunt in the bilge.
