Help eliminate the chance of scored rear cylinders and blown freeze plugs on your 5.9L Cummins with this Coolant Bypass Kit from Fleece Performance! The Fleece Coolant Bypass 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.

Very Stylisty Cover
Size: For iPad 10th / A16 (11th), Color: Light Pink
This is a great cover, the color is amazing. I purchase this and a matching bluethooth mouse and stylus, so I have the entire Pink family. The cover is semi soft to touch and looks very stylus. It great value for the money.

Good if you don't need a trackpad
Size: For iPad 10th / A16 (11th), Color: Light Pink
The keyboard is nice and tactile, the connection for both mouse and keyboard was seamless. Good product but I am reconsidering because I didn't realize how much I'd miss a trackpad.

Size and color
Size: For iPad 10th / A16 (11th), Color: Light Pink
I bought this for my daughter’s birthday and she absolutely loved it! The light pink color is exactly as shown in the pictures, really pretty. The keyboard feels comfortable to type on and she’s obsessed with the backlight colors. The pencil holder is a nice touch too, keeps everything neat. Definitely recommend! 🎀
