Replacement Intercooler Pump

This page started as a description of a drop-in replacement intercooler pump for the GMC Syclone and Typhoon. Over the past few years, others have discovered the need for similar circulation pumps for their air/water intercooler systems.

We originally found the Jabsco 59500-0012 circulation pump. We encountered supply issues with that pump about the same time we then discovered the Johnson CM30P7-1 pumps. We now carry only the Johnson pumps.
