Pierburg CWA100-3 PNP Coolant Pump kit
NOTE: A CWA-100-2 may be shipped instead due to supply chain issues. The flow rate is the same but the inlet/outlet manifolds are about 10mm longer on the CWA-100-2.

Dedicated Motorsports brings you a plug and play solution to replace the factory supercharger cooling pump found on the Gen2 CTS-V and ZR1 Corvette. The CWA-100-3 flows slightly better than very popular Varimax pump and is a direct replacement. This pump flows ~ 12 gallons per minute at ~ 7 psi system pressure. Which is a 30% increase over the Varimax. the DMS kit will come with a plug and play wiring harness for the 2009-2014 CTS-V or 2009-2013 Corvette ZR1 and a mounting clamp. If you need the pump for a different vehicle, we will supply an unterminated harness. Please select from the dropdown above. 

This pump is versatile enough to be an asset to any cooling system.
