Manufacturer Description

The Fleece Performance coolant bypass for the 2007-2012 RAM with 6.7L Cummins seamlessly integrates with your truck for an OE fit-and-finish.
Features:

Increased Coolant Flow, Decreased Coolant Temperatures
The rear cylinders on the 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 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.
Kit Includes:

  • Rear coolant bypass thermostat housing
  • Front coolant bypass thermostat housing
  • New EGR cross-over tube gaskets
  • Black braided nylon coolant bypass hose with protective high temperature sleeve and AN fittings
  • Mounting hardware

Must have for a young puppy
Size: Small (Pack of 1), Color: Blue
Very helpful for our young puppy. Cleaning it isn't the easiest, but cleaning advice is easily found online and it's worth the hassle to have a durable lasting toy around

Perfect for small senior dogs!
Size: Extra Small (Pack of 1), Color: Pink
So I actually bought this for my senior Bolonka. She has a neurological disorder that does not allow her to have hard bones or treats, plus I am trying to protect her teeth for as long as I can. This is a GREAT toy. I like to fill up the middle with yogurt or peanut butter and things she can lick instead of bite into. This is the PERFECT size for her. She likes to play with it even without a treat on the inside. She just carries it around the house , as its not heavy at all, and throws it around, it is too cute! It is not loud at all, the only noise that comes out is if shes got a ton of saliva and her teeth rub against it. I just pulled it off the packaging, washed it, and it was ready to go. It will last forever with my baby because she doesn't chew hard so I am unsure about the durability for bigger pups or dogs who are heavy chewers. I am so glad I got this for her and I would HIGHLY recommend it!
