Help eliminate the possibility of scored rear cylinders and blown freeze plugs in your 5.9 Cummins with this Coolant Bypass Kit from Fleece Performance! The Fleece Coolant Bypass with Stainless Lines solves the problem of excessive coolant pressure before it becomes a problem. The integrated secondary thermostat locates at the back of the block and allows coolant to flow freely when at normal operating temperatures ensuring consistent temperatures across all six cylinders and eliminates excessive pressure. The kit comes with high quality AN o-ring fittings and AN hose connections with braided hose to ensure a leak free installation and installs in two hours or less!

Increased Coolant Flow, Decreased Coolant Temperatures - The rear cylinders on the 24 Valve Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the cooling system, especially the rear of the block and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure. Fleece's coolant bypass kit adds 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.

Why do I need a Fleece Coolant Bypass? - One of the biggest issues on the 24 valves is the coolant flow problem to the rear cylinders. This can cause catastrophic failure or blow outs of the freeze plugs in an over-temperature / over-pressure condition. The Fleece Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform.

Must have!
I’m very happy with this. I waited until I was doing a transmission swap to install this and I’m glad I did! I wouldn’t attempt this with the transmission in. I also purchased a mishimoto 180 degree thermostat for the main thermostat housing and my pickup stays cool no matter what I’m using her for. The stainless braided hose is a little long but I hid the extra slack behind the engine. Worth every penny, a must have in my opinion.

Good call on installing with the transmission out. Work smarter, not harder. :) Thank you for your order and your review! -Ben
