E-0 Engine Zinc Anode 1/4" NPT x 1-3/4" Engine pencil zincs-complete with end plug Picture is of a larger size-for reference Review: Use with 5.7L HEMI in Jeep Commander - I purchased this to use in the water pump of my Jeep Commander with the 5.7L HEMI. Why? Because there was corrosion present in the sealing surface of the water pump to the timing cover. Yes, I am guilty of not changing the coolant often enough. The water pump had begun leaking profusely around the entire edge and I planned to replace it. Before installing the new water pump, I researched anodes like I had in my boat and had used in aluminum radiators previously. This specific anode will fit the small port on the top front of the HEMI water pump. It is short enough that no modification is necessary and will not contact the timing cover. After cleaning things up really well and using aviation gasket sealer -and- the included new water pump gasket seal, all went back together just fine. Yes, I need to check the quality of the coolant more often. Hopefully this anode will help prevent corrosion in between coolant changes. I will buy more since I have another Jeep with a HEMI. Review: works - time will tell if it works. but the boat definitely needed them ## Features - 1-3/4" Zinc Pencil Length - 1/4" NPT Brass Plug - 9/16" Wrench Size - 3/8" Zinc Rod Diameter - Made to Current Mil Spec A-18001K in the USA! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0088I38K0 | | Best Sellers Rank | #881,745 in Automotive ( See Top 100 in Automotive ) #466,360 in Automotive Replacement Parts | | Brand | Roto Metals | | Brand Name | Roto Metals | | Customer Reviews | 4.4 out of 5 stars 51 Reviews | | Item Weight | 0.05 kg | | Manufacturer | Rotometals.com | | Material | zinc, Brass | | Material Type | zinc, Brass | | Model | AM0144 | | Number of Items | 1 | | Part Number | AM0144 | ## Images ![Crusader Engine Zinc CRU10335 Zinc w/Plug (E-0) - Image 1](https://m.media-amazon.com/images/I/11waAysJxIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Use with 5.7L HEMI in Jeep Commander *by A***N on January 21, 2026* I purchased this to use in the water pump of my Jeep Commander with the 5.7L HEMI.

Where I took one of the blank 1/4 pipe plugs out. Had to shave it down in length slightly. Now it’s keeping the interior of my manifolds from corroding. I’ve checked it over the season and it’s working. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/26825181-crusader-engine-zinc-cru10335-zinc-w-plug-e-0](https://www.desertcart.pl/products/26825181-crusader-engine-zinc-cru10335-zinc-w-plug-e-0) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-09-22*
