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.

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.

Ok, Im older now. Everything in us girls changed as we age. Skin does to. Ichy, dry, uncomfortable in your own skin. So I saw this on Amazon, and got just to try. Wow!!! Easy to use, goes on smoothly. I don't know what's in that stuff but I know it works. My skin is so much better now. Give it a try. Take care.

Deep Hydration that Absorbs Quickly
Scent: Shea Butter, Size: 18 Fl Oz (Pack of 1)
My girlfriend loves this Olay Body Lotion. It leaves her skin feeling incredibly soft and hydrated all day long. As someone who appreciates quality products, I've noticed how well it absorbs without being greasy. The shea butter scent is subtle and pleasant. It's a high-quality moisturizer that delivers on its promises. A great addition to her daily routine.

Best lotion ever
Scent: Fragrance-Free, Size: 18 Fl Oz (Pack of 1)
Best lotion ever. This lotion actually heals and moisturizes your skin so it doesn’t just wash off in the shower. I only have to use it once or twice a week. It dries so fast I don’t have to wait to dress. It’s not greasy at all. I recommend this lotion to everyone. Bonus that it’s unscented because I can use it with my scented body oils. I stopped buying the scented lotions that go with my shower washes and oils and just use this.
