Fleece Performance 04.5-07 Dodge 5.9L Cummins Coolant Bypass Kit (06-07 Auto Trans)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.

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.

Very slow--5+ minutes to froth and warm milk
Color: White-Stainless
Pros-- Makes nice froth and warms the milk. Both froth settings produce the same kind of froth. it's relatively easy to clean-- usually just a strong rinse will do. It does fine in the dishwasher too. The noise level isn't bad. Cons--it takes between five and six minutes to froth milk. It is very slow. I can froth latte art milk on my espresso maker in less than a minute, by comparison. The forth it produces is too thick to make any kind of latte art.

Quality
Color: White-Stainless
What really impressed me is how fast it works—in just a couple of minutes, I have hot, creamy milk with thick, rich foam. The texture comes out smooth and fluffy, just like a coffee shop. It’s super easy to use, and cleaning it is quick too. I’ve used it for lattes, cappuccinos, and even hot chocolate, and it works perfectly every time. Definitely worth it if you want something quick, easy, and makes great foam in large amounts

Very nearly perfect!
Color: Matte Black
Admittedly, I'm writing this after making only one latte, but it was almost perfect! The milk was hot enough, but not too hot. The froth on my half & half was luxurious. It was super easy to use and select the what I want. I love the glass pitcher and being able to see my half & half as it heats and foams up. The only thing that isn't perfect, and I didn't take any off on my stars for, is that the frother is plastic. I'm striving for a plastic-free life and this Milk Frother and Steamer is very close to that, but heating plastic releases nanoparticles into the contents. I may have to buy another one, since it seems that there is no spare pitcher available to buy. Two pitchers would be very handy.

Easy to use, reliable machine
Color: White
Great product! I have a fully automated DeLonghi cappuccino/latte coffee machine. After 5 years of use, the machine's milk frothing function started to fail. I purchased this product to supplement/replace the milk frother on my DeLonghi automated coffee machine; it works great and produces copious milk froth with much less mess.

Best frother ever!
Color: White
This is the best frother ever! Works better than my expensive espresso machine frother. So easy and makes a large amount enough for 2 large cappuccinos.
