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.

Great value for the money and does the job!
Flavor Name: Mint, Size: 230 Count (Pack of 1)
These tablets work great for those who suffer with dry mouth at night. They stay put and deliver a slow and easy release to help keep your mouth from being dry. No worry about swallowing them- they stay put!! I prefer the mint flavor as the taste is very subtle and it doesn't have any smell to them. Great value for the money.

Effective Relief for Dry Mout
Flavor Name: Mint, Size: 230 Count (Pack of 1)
Oracoat XyliMelts have been a lifesaver in managing my dry mouth symptoms, especially at night due to medication side effects. Ease of Use: These discs are simple to use; I place two in my mouth before going to bed, and they adhere comfortably throughout the night. They’re discreet and easy to apply, making them convenient for both nighttime and daytime relief. Effectiveness: XyliMelts work effectively to stimulate saliva production, providing much-needed moisture to alleviate the discomfort of dry mouth. I wake up with less dryness, which greatly improves my comfort and oral health. Flavor and Comfort: The mild flavor is pleasant and doesn’t interfere with sleep. The discs dissolve slowly, ensuring consistent relief without any irritation. Overall Experience: Oracoat XyliMelts are a must-have for anyone dealing with dry mouth from medications. They offer reliable, long-lasting relief and have become an essential part of my nightly routine.

A Tooth Saver
Flavor Name: Mint, Size: 230 Count (Pack of 1)
Work well. My mouth gets dry due to meds and this helps me avoid cavities while sleeping. It has a mild minty taste ad lasts most of the night. I sometimes use it during the day as well and it is nice and discreet.

Best relief for dry mouth!
Flavor Name: Mint, Size: 230 Count (Pack of 1)
My neurologist recommended XyliMelts after I mentioned dry mouth with CPAP use. I have been using them for about a year and they’ve made a huge difference. Before using them, I would wake up several times with a completely dry mouth and throat. These help keep my mouth moist for hours while I sleep. They stick well to the roof of my mouth without being uncomfortable, and the mild mint flavor isn’t overpowering. I also like that they dissolve slowly instead of disappearing too quickly like regular lozenges. The only small adjustment was getting used to placing them the first couple of nights, but after that they were easy to use. Overall, I’d definitely recommend these to anyone dealing with nighttime dry mouth or dry mouth from medications. Pro tip: bring them with you when you travel, they are super helpful in drier climates and on planes.

Works well but too expensive
Flavor Name: Mint, Size: 230 Count (Pack of 1)
We love these for nightime. Wish they didn’t stop making the cinnamon, but we like the mint anyway. Excellent for dry mouth esp at night! Too expensive though.
