Vanshly Sea Water Pump Threaded Impeller Repair Kit 21700445 Aluminum

Description

Product Overview

Vanshly’s Sea Water Pump Threaded Impeller Repair Kit (model 21700445) is engineered to deliver a reliable solution for restoring the water circulation pathway in a wide range of gasoline‑powered engines. The kit centers on a precision‑machined aluminum impeller that combines lightweight construction with exceptional resistance to corrosion, ensuring long‑term performance even in harsh marine or high‑temperature environments. Each component is finished to tight tolerances, providing a seamless fit with the original pump housing and eliminating the need for additional adapters or custom machining. The threaded design of the impeller allows for secure attachment, reducing the risk of loosening under vibration and maintaining consistent water flow during prolonged operation. With a package weight of just 7.8 ounces and compact dimensions of 4.41 × 2.44 × 2.32 inches, the kit is easy to store, ship, and handle during installation. The inclusion of the manufacturer part number 21700445 guarantees compatibility with OEM specifications, while the machined exterior surface contributes to a quiet, efficient pump operation that supports optimal engine cooling. The kit also comes with a detailed instruction sheet that guides users through each step of the replacement process, from removing the old impeller to torque‑specifying the new component for optimal performance. By using this repair kit, technicians can avoid the expense of a full pump replacement, extending the service life of the existing water pump assembly and delivering cost savings for both hobbyist mechanics and professional service centers.

Usage

This repair kit is suited for a variety of gasoline engine families, including V8, V6, and other configurations listed in the compatibility chart. It works equally well in automotive cooling systems, marine outboard engines, and small‑engine applications such as generators and lawn‑mower power units where water pump reliability is critical. The threaded impeller design simplifies the removal of the old part and allows the new impeller to be installed without extensive disassembly of the pump housing, making it an ideal choice for on‑site repairs in workshop bays or field service environments. Users should ensure the engine is cooled and the pump is depressurized before beginning the replacement, then follow the step‑by‑step guide provided. After installation, the engine should be run through a break‑in cycle to verify proper water flow and temperature regulation. Regular maintenance checks can further extend the lifespan of the impeller, especially in high‑temperature or salt‑water conditions where corrosion can accelerate wear.
