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.

All-Day Comfort, Perfect Semi-Casual Office Shoes
Color: British Tan/Java, Size: 10
Amazing, comfortable shoes for the office. These are by far the best I’ve tried for a semi-casual look. They’re incredibly lightweight and feel like you’re not wearing anything at all. Perfect for all-day wear.

Good, but you sacrifice a few things in favor of style
Color: Black Leather/Black, Size: 10, Color: Black Leather/Black, Size: 10
It’s much better than other shoes out there, but the design is slightly confusing. The first thing you have to know is that the shoe won’t be mind blowingly soft, but it is around as comfortable as standing on something like vans shoes. The holes on top are both a plus and a minus, when you step in a puddle, your feet get instantly soaked, but just by walking around for a bit, they dry up again. Then these holes reduce the structural integrity of the shoe, so I expect the top to be the first part of the shoe that deteriorates, when usually for all my other shoes, it’s the sole that falls off first. With the holes, you can’t shine them the traditional way, you have to be more careful as you might get goo into the inside fiber. Finally you can’t run in these, they’re larger than your foot which is quite comfortable while just standing or walking, but I’m sure they’ll tear if you don’t watch your footing. If all that is okay with you, You’ll get quite a few compliments on it as you walk around, because these are beautiful and excellent as a dress shoe/loafer hybrid
