Product Details
This aftermarket zinc sacrificial anode is intended for Volvo Penta inboard applications. Sacrificial anodes help protect compatible underwater metal components from galvanic corrosion by wearing in place of the protected component.
The product is listed under aftermarket reference 18-6001. Company catalog records list the following Volvo Penta OEM references for this product: 3838499, 800476, 804107, 838929 and 858501.
Before ordering, compare the reference number and the physical design of your existing anode with the information in your engine or cooling-system service documentation. Exact fitment may depend on the engine, cooling arrangement, application and serial-number range.

Installation Notes
- Switch off the engine and allow it to cool completely before beginning work.
- Close the relevant seacock or otherwise follow the service procedure for the cooling system to control water or coolant flow.
- Place a suitable container beneath the installation point to collect any draining fluid.
- Remove the existing anode according to the engine or cooling-system service manual.
- Compare the replacement anode with the removed part, including the anode shape, mounting arrangement and reference number.
- Clean the mating area and threads as directed by the service procedure. Do not force a mismatched thread or fitting.
- Install and tighten the anode according to the manufacturer's specified procedure and torque requirements.
- Restore the cooling-system or seacock configuration, start the engine when safe, and check carefully for leaks.
Professional installation is recommended when the correct application, mounting arrangement or service procedure is uncertain.
Maintenance and FAQ
What does a sacrificial anode do?
A sacrificial anode is designed to corrode preferentially to help reduce galvanic corrosion of compatible metal components in the marine system. The anode is a wear item and must be inspected periodically.
How often should this anode be inspected?
Inspection frequency depends on water chemistry, salinity, operating conditions and usage. Follow the engine manufacturer's maintenance schedule and replace the anode when it is significantly consumed, damaged or no longer provides the required protection.
Does 18-6001 replace Volvo Penta 838929?
The Sierra catalog identifies 18-6001 as an anode that replaces Volvo Penta reference 838929. Confirm the remaining references and the physical configuration against your specific application before ordering.
Can I use this for any Volvo Penta diesel engine?
No universal engine-model claim should be assumed. The product is identified for Volvo Penta inboard applications, but exact fitment must be confirmed using the applicable OEM reference, parts manual and engine or serial-number information.
Is this an OEM part?
No. This listing is for an aftermarket replacement anode. The Volvo Penta numbers shown are OEM reference numbers used for application identification.
Safety and Important Information
- Verify the OEM reference, mounting arrangement and physical dimensions against your original part before purchase.
- Do not install an anode with a different thread, fitting or configuration merely because the engine family appears similar.
- Use the anode material appropriate for your operating water and follow the engine manufacturer's recommendations.
- This is an aftermarket replacement, not an OEM-manufactured component.
