Flowkooler 1745 FLOKOOLER Water Pump for 87-90 Jeep Wrangler YJ with V-Belt on 2.5L I-4 or 4.2L I-6 Engine

Flow Kooler 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 has proven that Flow Kooler water pumps produce 20% more gallons per minute at 2000 RPM and 100% more gallons per minute at 900 RPM than any other pump on the market today, including expensive racing pumps.

Flow Kooler 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 Flow Kooler water pump is up to 32% more efficient than other pumps, meaning less horse power 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.
