This Sierra Impeller Kit, part number 223-3300, is a replacement water pump impeller kit built for Onan generator sets. It directly replaces Onan part 132-0349 and is designed to restore proper raw water circulation in the generator's cooling system, helping prevent overheating and pump failure. The kit is constructed from plastic and rubber components engineered to meet or exceed the performance of the original equipment part it replaces, giving generator owners a reliable option when the factory impeller wears out, cracks, or loses its vanes from age or dry-running.

The impeller kit is sized at 6 x 2.5 x 6 inches and weighs 0.33 pounds, making it a compact, straightforward component for scheduled maintenance or emergency replacement. It is intended for a specific set of Onan generator models, including standard and isolated-ground configurations, so buyers should confirm their generator model before ordering. Sierra backs the kit with its standard warranty covering defects in workmanship and materials for the useful life of the product.
