Fleece Performance 98.5-02 VP Coolant Bypass Kit w/ Stainless Steel Braided LineIncreased 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. Application Notes: The 2003 - 2007 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger. The heat exchanger is designed for use in cold climates to warm the transmission fluid with the engine coolant.

Simple and Effective for Fresher Breath!
I decided to try these stainless steel tongue scrapers, and I'm glad I did. You get a pack of two, which is convenient. They feel really sturdy, being made of surgical steel, and they are easy to clean. I've noticed a difference in how fresh my mouth feels since I started using them. It's a simple addition to my oral hygiene routine, but it seems to make a real impact on breath freshness. If you're looking for a durable and effective tongue cleaner, this two-pack is a good option.

Moisturizing spray that works
Size: 0.75 Ounce (Pack of 2)
I have a very dry mouth due to medical conditions. I use this mouth spray at night because it was so hard to sleep through the whole night with such a dry mouth. Using the spray before bed I’m able to sleep through the entire night!
