The Fleece Performance coolant bypass for the 2007.5-2012 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.

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.

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

Nice watch at a very good price.
Color: Gold Silver Stainless Steel/Black Dial-2870
Favorite watch in my collection. I wear it every day, and at the price point, if breaks in six months I will buy another just like it.

Best cheap time piece there is
Color: Gold Silver Stainless Steel/Blue Dial-2870
I’ve been a chef for years and having a great watch that keeps time as well as it looks classy is a tough ask when you’re exposing said watch to high heat over the range, extreme lows putting away vendor orders in the walk in fridge or freezer (sometimes up to an hour or 2 at a time), getting popped with hot oil and sauces, and doing dishes when our dishwasher is a no show. I do take this off to make seasoned flour for fried chicken or seafood, but it can easily be kept clean and it keeps time EXTREMELY well. I get several compliments on it from other chefs and even the guests at our restaurants both in downtown Charleston and the resort at Kiawah Island. Just don’t bang the face of the watch into a steel prep table (it will chip or scratch). But it is possible to replace the face at a local jeweler, and at any desired quality or price bracket. I own this watch in several colors and have used them for 2 years now. I’ve been very happy with OLEVS all around.

Affordable, comfortable, and practical watch
Color: Gold Silver Stainless Steel/Green Dial-2870, Color: Gold Silver Stainless Steel/Green Dial-2870
This watch is very good for its price range, of course this isn’t a Seiko, but what do you expect for under $50. I’m extremely excited about this watch and just finished removing some links for it to fit. That’s the worst part removing the links which is very difficult even with the tool that was supplied. Now, we’ll see how long the watch will last and hold up after everyday being worn. It’s a good looking and comfortable watch that’s inexpensive.
