Cummins Coolant Bypass Kit

Published in the September 2013 Issue September 2013

Built out of necessity, Fleece Performance re­cently released the Cum­mins Coolant Bypass Kit. The rear cylinders of a Cummins en­gine suffer from a lack of coolant flow, which results in high coolant tem­peratures and excessive pressures. This kit is designed with a secondary thermostat that, unlike other brands, works based on temperature instead of pressure, solving the problem before pressure becomes an issue and ensuring consistent temperatures across all six cylinders.

Currently offered for any 2003 to 2013 Cummins engine with prices starting at $389.
