Manufacturer Description

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.

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.

Gentle, Effective, and Easy to Use, A Great Daily Fiber Boost
I’ve been incorporating Benefiber Healthy Shape Prebiotic Fiber Supplement into my daily routine for a few weeks now, and overall, it’s been a very positive experience. The product mixes easily into water, smoothies, or even coffee, without leaving behind any gritty texture or noticeable flavor, something I really appreciate. It makes it simple to get my daily fiber intake without changing my meals or dealing with unpleasant textures. In terms of performance, it’s been gentle on my stomach and has helped regulate digestion gradually, which is ideal if you're looking for something non-irritating and safe for daily use. I also noticed feeling slightly fuller between meals, which helps with appetite control, though I wouldn't call it a magic solution for weight loss. The prebiotic aspect is also a plus, since it helps support gut health in a natural way. The container is compact, easy to store, and the scoop makes dosing simple. Pros: Mixes well in drinks without taste or texture Gentle and non-irritating Helps with digestive regularity Prebiotic benefits for gut health May reduce appetite slightly Cons: Results are gradual, not instant Doesn’t completely curb hunger Slightly more expensive than similar options Benefiber Healthy Shape is a reliable daily fiber supplement that delivers on what it promises: a gentle boost to digestive health and satiety. While it’s not a weight-loss product, it helps you stay regular and feel fuller.

Me gusta por no tener sabor
Me gustó pero es muy poco el contenido. Creí que traía dos unidades y no. Creo que me confundí. Me gusta porque es sin sabor y puedes utilizarlas con diferentes bebidas sin alterarles el sabor. No puedo hablar mucho del resultado porque al ser poca entiendo que debía tomar por mas tiempo.
