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.

On my second bottle...
Scent: Rain Water, Size: 33 Fl Oz (Pack of 1)
I've now purchased two bottles of this hand soap. I love the smell! The soap itself is gentle but effective. It cleans well without drying out my hands, even with frequent use. I appreciate that it’s made with ingredients like aloe vera and essential oils, which helps keep my skin feeling soft instead of stripped. The scent is light, fresh, and clean without being overpowering. The “Rain Water” fragrance has a subtle, slightly floral smell that makes washing your hands feel a little more refreshing and enjoyable.

Great when applied correctly!!
Color: 02 - Untinted (1.7 oz)
Great sunscreen!! I was looking for a new sunscreen after I was prescribed tretinoin and sunscreen is a must! It hasn't broken me out and have noticed my skin tone is more even. I was having issues of the sunscreen pilling so my advice would be to pat into the skin first and then rub to fully blend it in. I do wear makeup everyday so applying this way makes my makeup lay so flawlessly. It has that sunscreen smell that lingers after application but it feels so hydrating that I don't always need to also use a moisturizer, applied right after toner and serums in the morning.

Great for sensitive skin protection
Color: 02 - Untinted (1.7 oz)
I have very sensitive skin especially anything that has SPF in any amount over 15. Since I have had a few issues with skin cancer on and around my face I needed something that had a greater SPF rating. This has worked great! I have not had any allergic reaction to it! It goes on smoothly, not heavy and provides good protection.

Fantastic sunscreen!
Color: 02 - Untinted (1.7 oz)
This stuff is worth the price. We use it daily. It goes on clean, not greasy. Smells great and provides excellent sun protection. We’ve used it at the beach on occasion and it protects for several hours. I am exposed to sun for many hours at work and this provides great protection for my face. It IS expensive, however, one pump applied to my face is enough to protect my face for many hours at work. I usually apply one to each arm as well. I’ve yet to find something that goes on as well, smells great and leaves your skin feeling moisturized while adding great protection. In my opinion it is worth the price.

Effective sunscreen protection
Color: 02 - Untinted (1.7 oz)
This product goes on smooth under makeup or by itself. It works great! I have applied the sunscreen at 8:00 in the morning and been in and out of the sun throughout the day and received no sunburn. I felt confident my skin was protected all day.
