Sierra 18-6001 Zinc Anode for Volvo Penta Fresh Water Coolers, Replaces 838929

The Sierra 18-6001 is a zinc sacrificial anode engineered for use with Volvo Penta fresh water cooler systems. Made from a high quality zinc composition, it provides corrosion protection by sacrificially wearing away in place of surrounding metal components, helping to extend the service life of the cooling system it is installed in. The anode features a machined exterior for a precise, consistent fit and is manufactured to meet or exceed the quality of the original equipment part it replaces.

This anode is a direct cross-reference match for GLM 12789 and Volvo Penta 838929, making it a straightforward replacement for boat owners maintaining Volvo Penta fresh water cooling systems. At just 0.09 pounds, it is a lightweight, low-cost maintenance item that should be inspected and replaced periodically as part of routine sacrificial anode upkeep to protect against galvanic corrosion.

Frequently Asked Questions

What does the Sierra 18-6001 anode fit? The Sierra 18-6001 is designed for use with Volvo Penta fresh water cooler systems.

Is the Sierra 18-6001 the same as GLM 12789? Yes, the Sierra 18-6001 zinc anode cross-references directly to GLM 12789, so either number identifies the same replacement part.

Does the 18-6001 anode replace Volvo Penta 838929? Yes, the Sierra 18-6001 is interchangeable with Volvo Penta part numbers 838929 and 838929-8.

What material is the Sierra 18-6001 anode made from? It is made from a zinc composition, which is standard for sacrificial anodes used in marine cooling systems.

How much does the Sierra 18-6001 anode weigh? The Sierra 18-6001 zinc anode weighs 0.09 pounds.

What are the dimensions of the Sierra 18-6001 anode? The Sierra 18-6001 measures 0.39 x 0.39 x 0.39 inches.

Is this a genuine Sierra part or an aftermarket copy? The 18-6001 is a genuine Sierra product manufactured to meet or exceed the quality of the original equipment anode it replaces.

Why does a fresh water cooler need a zinc anode? A zinc anode like the Sierra 18-6001 sacrifices itself to galvanic corrosion, protecting the surrounding metal components of the fresh water cooler from corroding instead.

How often should the 18-6001 anode be replaced? Sacrificial zinc anodes such as the Sierra 18-6001 should be inspected periodically and replaced once significantly worn to maintain continued corrosion protection.

What finish does the Sierra 18-6001 have? The Sierra 18-6001 anode has a machined exterior finish for a precise, consistent fit.
