FlowKooler Water Pump | Ford 5.0L (302) & 5.8L (351W) | 87-96 Ford Bronco & Truck SKU: FK1656

FlowKooler Water Pump | Ford 302 or 351W | 1987-96 Ford Bronco & Truck

Built for 1987-96 Ford Bronco & F-Series Trucks that work hard in the dirt and heat, the FlowKooler high-flow water pump tackles low-speed overheating head-on. Designed for Ford 5.0L (302) and 5.8L (351W) engines, this pump doubles coolant flow at idle and low RPMs, making it ideal for crawling trails, towing, or sitting in slow traffic on a hot day. At the heart of this pump is a CNC-machined impeller with a larger diameter, more vanes, tighter tolerances, and enhanced porting to push coolant harder and smarter.

Backed by independent testing from major OEMs and universities, the FlowKooler water pump delivers performance gains you can measure—up to 30° lower temps, better cylinder wall cooling, and the ability to prevent vapor lock by stopping steam pockets from forming. With its military-grade anodized finish and lightweight aluminum body, it’s a serious upgrade over old-school cast iron pumps.
