Fleece Performance 94-98 Dodge 5.9L Cummins 12V Coolant Bypass KitIncreased Coolant Flow, Decreased Coolant Temperatures The rear cylinders on the 5. 9 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

Increased Coolant Flow, Decreased Coolant Temperatures The rear cylinders on the 5.9/6.7L 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. Kits for MY 2003+ include billet hose brackets. Why do I need a Fleece Coolant Bypass? One of the biggest issues on the 5.9/6.7L 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. The '03-'07 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger. The heat exchanger is not a fluid cooler, it was designed for use in cold climates to warm the transmission fluid with the engine coolant. It is not necessary for use in warm climates or high horsepower applications, nor does it detrimentally affect the trucks performance when removed. All 07-13 6.7 trucks, both automatic and manual equipped transmissions, do not have a transmission fluid heat exchanger.

Have size 4 🙌🏻 qreat quality, comfy, cute
Size: 4 Toddler, Color: Brown, Size: 4 Toddler, Color: Brown
Durabilty 💯 survived a beach trip on a 2 year olds feet and still look brand new! Guessing they are comfy, because she never acted or said otherwise. Definitely worth what we paid. Super cute, good quality, but could still spray out sand with no issues and let her run around and do all the toddler things. The brown is the perfect brown, it changes shades in different lighting and is not too light or dark. Good, cute and comfy sandal! Our girl has eczema and this material rubbing on her ankles didn't bother her as much as some sandals, so, tolerable on sensitive skin 👍🏻 also, the straps were a perfect angle and length for her petite ankle, other brands have to bend and rub her ankle. Lastly, the size seems true to normal toddler shoe sizes. They fit very similar to other of her sandals in the same size. Which reminds me, grateful to find a size 4 for our small feet girly 🙌🏻 not many options.
