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.

Nice chew toy
Color: Dinosaur, Size: Small
I have a small dog that loves chewing on these. It’s a bit pricey, but it helps keep her teeth clean, so I will pay this over her needing tooth extractions and a vet bill.

Not chew proof for little puppies
Color: Rings, Size: Small
Our first Chihuahua when she was a puppy loved chewing on this and pieces never came off. Our second Chihuahua I guess was a heavier tour and he was able to get pieces flaked off.

Great for teething puppy
Color: Pacifier, Size: Small
I was trying to find something very sturdy for our puppy that she could not bite pieces off of and this toy has been great. She loves it and it has held up very nicely. They are not soft so it is great for our teething pup. They are also the perfect size if you have a bigger pup like we do. She is a 4 month old pit mix. I would say they would be too big for a small breed puppy
