FlowKooler water pumps solve low-speed overheating problems by doubling the water flow rate at low RPM & idle. At 3,500 RPM the flow rate returns to normal to prevent excess water flow at high speed. Independent testing proves that FlowKooler water pumps produce 20% more gallons per minute at 2000 RPM & 100% more gallons per minute at 900 RPM than any other pump on the market today, including expensive racing pumps.

Lifetime Limited Warranty.

Product Details

FlowKooler pumps also generate 22% more water pressure inside the engine block than other water pumps. This increased pressure helps suppress engine hot spots, steam pockets, and pinging. In addition to higher output, the FlowKooler water pump is up to 32% more efficient than other pumps, meaning less horsepower is required to turn it. The result is overall lower operating temperature by as much as 30 degrees when cruising at low speeds. All pumps are brand-new (not rebuilt) and are covered by a lifetime warranty.
