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.

Perfect Flavor: NONE
Style: Unflavored (Pack of 1)
I see reviews writing "it tastes bad". Get over it you big babies! It doesn't. I have an allergy to peppermint and other unnatural man-made toxic flavorings and this is perfect! After the first few times the flavor is irrelevant and you get used to it. It cleans and cleans well. I don't wake up after brushing before going to bed with a mouth full of slimy coating on my teeth and bad aftertaste like I did with the other fake flavored toothpastes. I use Cleure for all my teeth brushing and haven't had any dental problems. The paste is smooth and I don't have irritation. It's great...I just wish the price point was a little lower since there's less added garbage in it.

Gentle, No harsh ingredients, no taste!
Style: Unflavored (Pack of 1)
This is the toothpaste you want if you want no additives or nothing. There's really no taste to it, but that's the whole idea you're getting no additives no nothing. It does have baking soda, and xylitol these are two great ingredients but overall it's very gentle. If you're having any problems with skin or anything and you feel it could be from either fluoride, mint flavoring, SLS, or coconut oil or all the other stuff they put in there give this a try! I'm on my second tube! Yes you're not going to feel as super clean as the other ones but that's because it's not stripping everything off your teeth like the other ones do it's very gentle and if there's any issues with sensitivity or anything like that this is the way to go.

Good ingredients
Style: Unflavored (Pack of 1)
The ingredients in this may appear to be boring, but for a fragrance-free, flavor free, toothpaste this one is not bad at all. It has a little bit of sweetener in it and it does a good job at leaving my mouth feeling clean and my teeth polished. I am very happy with this product and it is replacing a similar product that I was not happy with. This is a product I will reorder and continue to use as I am happy with the cleanliness and freshness.

No flavor toothpaste with a high price
Style: Unflavored (Pack of 3)
Great product at a not very great price. Maybe you came across this product while searching for unflavored or flavorless toothpaste. Well this does the trick it has no minty flavor to interfere with your morning coffee or your autism. But why does less ingredients mean a higher cost? I’m looking for something bare bones, no taste, and cheaper than the toothpaste they sell at most stores filled with chemicals! Why is this so hard to find?

Acid Reflux and LPR
Style: Unflavored (Pack of 1)
I follow a dietician for those who deal with Acid reflux and LPR. Being without flavor especially peppermint, as mentioned by the dietician, can be helpful for some. I have found this to be true with this product. It seems to have helped reduce, or at least not add to, my feeling of throat and mouth burning.
