The Fleece Performance coolant bypass for the 2013-2018 RAM with 6.7L Cummins seamlessly integrates with your truck for an OE fit-and-finish. Features Increased Coolant Flow, Decreased Coolant Temperatures The rear cylinders on the 6.7L 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. Our 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. Benefits Lowers coolant temperature at the rear cylinders Ensures consistent temperatures across all cylinders Prevents damaging coolant pressure build up Complete kit comes with braided hose and AN O-ring fittings to ensure a leak-free installation. Why do I need aFleece Coolant Bypass? One of the biggest issues on the 6.7L Cummins 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. Kit Includes: Rear coolant bypass thermostat housing Front coolant bypass thermostat housing New EGR cross-over tube gaskets Black braided nylon coolant bypass hose with protective high temperature sleeve and AN fittings Mounting hardware

My daughter LOVES these and wears them daily. She says they're really comfy and they slip on easily. They've held up for several months of daily wear so far and are still going strong!

Great for busy feet

My five-year-old daughter loves these Skechers slip-ins—and she is not easy on her shoes! You can see in the photo, she’s already put plenty of miles on them. They’ve been through the washing machine at least twice and still look great—the bright colors are a big hit with her and they hold up well in the wash. One of the elastic bands on top did come loose, but I was able to fix it quickly with a dab of superglue. She slips them on and off all by herself, which is perfect as we’re still learning to tie laces. All in all, a great purchase for the price—especially since kids grow so fast and put their shoes through a lot!
