The Fleece Performance coolant bypass for the 2007.5-2012 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 Braided nylon coolant bypass hose with protective high temperature sleeve and AN fittings Exhaust back pressure sensor mounting block and back pressure sensor line Mounting hardware

Sturdy, high-quality components
Color: Vivid Orange1, Size: 16pcs
Well-made reamer and plug inserter, as well as the 10 plugs, and the accessories. Even the pouch is high quality. Included instructions are very clear -- just be sure not to insert the plug with too much force, or you'll put the entire plug thru the hole. It's so much easier for a simple in-situ scooter tire puncture repair, where removing the tire can be much more time-consuming than removing a car tire. Including the high-quality little water/soap solution mister is a thoughtful feature. I highly recommend.

The small set is convenient to carry.
Color: Vivid Orange1, Size: 16pcs
It works well and has a non-slip handle. Although there aren't many blades, it's enough for a family. The accessories are small but practical.
