Fleece Performance 03-07 Dodge 5.9L Cummins Coolant Bypass Kit (03-05 Auto Trans)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.

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.

Bought as a gift
The young man is using the book to understand that we all have different love languages and I watch as he take interest in the content of the book. I gave both my daughters a copy last Christmas as part of their gifts as well. I have my copy of the book and it has helped me to understand others as well as myself more profoundly. Everyone one should get a copy for themself…a must have to help build better relationships.

Prescriptive approach to eye-opening information
This book has changed my perspective for the better. It is very prescriptive in its approach, but that's just what I needed. Not only can I better understand the love expressed by others in their unique way, but I have a better concept of how to express love in different "languages" and even "dialects." My understanding of others has greatly improved. I'm more excited to think of different ways to express my love. I just can't say enough about this book. It is well worth a second read as well just to be reminded of all the important messages. It also includes portions about controlling anger and apologies. The book doesn't contain information that's mind blowing, but the way it's presented can be life changing for some. It's the package deal on how to be a better lover.

Recommend this book
Gary Chapman defines the daily tasks of Love and the work made to sustain a relationship as compared to the false notions that the media portrays about love which are actually false. This is new learning and excellent book on love. I only recommend this book on love and no other.
