About FlowKooler

Most people know Paso Robles, CA for its wine but we also manufacture here. On the central coast of California halfway between San Francisco and Los Angeles is where FlowKooler makes hi flow water pumps and more. 

We have over one hundred and twenty different hi flow water pumps and we cover thousands of applications but we don't stop there.  We design bespoke impellers for individuals, race car teams and industrial applications and we restore pumps with our impellers when the castings are obsolete or the numbers matching car just can't stay cool.

Visit our online catalog to determine which pump will help your vehicle overcome its overheating problem or contact us if you need help rebuilding a pump.

If you need further cooling assistance you may contact FlowKooler's sister company, The Brassworks. The Brassworks has been manufacturing radiators since 1976. With a focus on brass era car radiators, veteran car radiators, classic car radiators, and custom street rods we serve a worldwide customer base of end users, professional builders, collectors, restorers and museums.
