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 and up 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.

super deal !!
Color: 1-colorful Blue
i got this purse on a special deal pricing for 19.99 & wow what a steal...........its a well made purse........vibrant color....its more a matte finish instead of shiny.........and if ur familiar with brahman this would be the small duxbury style...........im so glad it was the smaller one because the large duxbury is just awkwardly too big for petite gals like me lol.............very happy with my purchase & so glad i found this company............im an avid brahman fan as well & when i saw styles that brahman discontinued & now this company has them i was very happy :) these are excellent dupes but keep in mind they are dupes & price range is super so lining may be a bit thinner but not a deal breaker for me - lining was fine enough to hold up & instead of leather they use vegan leather - but dont be scared lol the vegan leather they use is very heavy duty & will hold up............im not a fan of vegan leather but i made an exception for this company............please keep making this style as well as the other styles u have - im a super fan !!! (ps- the small duxbury is still in use by brahman - its not discontinued - others styles on this companies websites are discontinued by brahman - so if u dont want to pay over 200.00 then this is an excellent option )

Well made, stylish handbag and a eye-catching color
Color: 1-bright Orange
I am very happy with the look and quality of this handbag; the fabric inside, and especially the deep, rich orange color I ordered - it does not appear to be available right now. I am glad to have chosen a solid color over some of the varied tones that appear harsh and cheap. I have not used the shoulder strap yet; the handles are comfortable to carry on the arm. I generally buy leather purses only so it is a pleasant surprise to be enjoying this vegan material, which looks more expensive than the price I paid.
