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.

Ideal Golf Shirt at Great Price!
Color: Teal Sweep Men, Size: X-Large
I purchased multiple golf shirts in different patterns as gifts just like this one and all were very satisfied with the gift. The different patterns give you an opportunity to purchase these as a more personal gift for whoever your purchase is for. The fabric quality is wrinkle resistant with a soft texture and comfortable wearability. I purchased for men ranging from 175-250 pounds and all seem to fit true to size. If you want extra room, I would definitely consider sizing up for extra room in the shoulder width or waist. The sleeves and length of the shirt seem to be true to size. Last but not least, the price of this item has to be one of the best I have found when it comes to golf shirts.

Love the material. A stretchy sheen. Husband loves the “wicking” quality. Nice looking quality shirt! I’m going to order a couple more in different colors.
