Fleece Performance Coolant Bypass
The Fleece Performance Coolant Bypass solves the major problem of the Cummins engine being able to cool properly when adding any amount of horse power no matter how small.
What is the Fleece Performance Coolant Bypass?
The Fleece Performance Coolant Bypass is a kit that is easily installed in around an hour, but is worth what it can do for a lifetime! This is able to help the Cummins engine take the problem it can have with cooling when adding any horsepower over the stock factory number that Cummins provides. This is a very common issue that plagues many many trucks and can cause a lot of issues.
Why do I need this?
The Cummins Engine is a incredible platform that can do honestly just about anything you need it to do! The rear cylinders suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the system, especially the rear of the block and possibly blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure. Fleece Performance has designed this coolant bypass kit with a secondary thermostat, that unlike other brands, works based on temperature instead of excessive pressure. This solves the problem before pressure becomes an issue by ensuring consistent temperatures across all six cylinders. The Fleece Performance kit comes with high quality AN o-ring fittings and AN hose connections with braided hose to ensure a leak free installation.

The parts are of a great quality, with the CNC machined parts and braided lines ensure a quality fit and quality that will work for you every time and continue to work for you time and time again! This is the kit you need to have on absolutely every Cummins truck on the road and on the track.
