PRW Performance Quotient Flow Aluminum Water Pump for Mopar 318‑360

Description

Product Overview

The PRW Performance Quotient water pump is a purpose‑built component designed to meet the rigorous demands of Mopar 318‑360 engines produced between 1969 and 1985. Constructed from a pressure‑injected aluminum alloy, the pump housing offers a lightweight yet exceptionally strong structure that resists corrosion and warping under high‑temperature conditions. The internal impeller is CNC‑machined from cast iron, delivering precise blade geometry for optimal coolant acceleration and flow consistency. Steel hubs and heavy‑duty shielded‑seal roller ball bearings provide smooth rotation and extended service life, while the back‑plate “O”‑ring seal ensures a leak‑free interface even in competition‑grade applications. With dimensions of 14.25 x 9 x 8.25 inches and a weight of just 7.84 pounds, the pump fits easily into the engine bay and aligns with the universal fit specification, making it a direct replacement for OEM part number 1431810. Additional features include a polished finish housing for improved heat dissipation and a machined exterior that enhances both aesthetics and functional airflow. This pump is engineered to maintain coolant pressure, reduce hot‑spot formation, and support sustained high‑rpm operation without sacrificing reliability.

Usage

The Performance Quotient pump excels in a variety of environments, from daily street driving to high‑performance racing scenarios. For classic car enthusiasts restoring vintage Mopar trucks, the pump provides a modern upgrade that respects original specifications while delivering contemporary cooling efficiency. In off‑road or heavy‑load applications, the robust bearing assembly and aluminum body handle increased thermal loads, preventing overheating during prolonged climbs or towing. Motorsport teams appreciate the pump’s competition‑grade O‑ring sealing, which eliminates coolant loss during aggressive cornering and rapid acceleration. The pump is also suitable for custom builds where engine swaps demand reliable coolant circulation without extensive modifications. Installation is straightforward: the pump bolts directly to the engine block using the original mounting points, and the included gasket set ensures a secure seal. Whether the vehicle operates in hot desert climates or cooler northern regions, the pump’s design maintains consistent coolant flow, protecting critical engine components such as the head gasket, pistons, and cylinder walls.

FAQ

What vehicles are compatible with this pump?

The PRW Performance Quotient pump is engineered for Mopar 318‑360 engines found in trucks and performance vehicles produced from 1969 to 1985. It fits the original OEM mounting points and replaces part number 1431810, making it a direct swap for any vehicle that originally used that pump.

How does the aluminum construction improve performance?

Aluminum offers a high strength‑to‑weight ratio, which reduces the pump’s mass and improves heat transfer. The material dissipates heat more efficiently than cast iron alone, helping to keep coolant temperatures stable during high‑rpm operation. Additionally, aluminum resists corrosion, extending the pump’s service life.

Can this pump be used in high‑performance racing applications?

Yes. The pump’s O‑ring sealed back plate and precision‑machined impeller are designed for competition‑grade reliability. The robust bearing assembly handles the increased centrifugal forces and thermal loads encountered on the track, ensuring consistent coolant flow without leaks.

What maintenance is required for the pump?

Routine maintenance includes checking the coolant level and condition, inspecting the O‑ring for signs of wear, and verifying that the bearing housings remain free of debris. The pump does not require internal lubrication; the sealed bearing design is self‑contained. Replacing the O‑ring during a coolant flush is recommended to maintain optimal sealing performance.

Is there a warranty or support if the pump fails?

PRW provides a limited warranty covering manufacturing defects for a specified period after purchase. In the event of a failure, customers can contact PRW’s technical support team for troubleshooting assistance, replacement parts, or a warranty claim. Detailed warranty terms are included with the product documentation.
