Just in time for Summer! Our all-new Fleece Performance coolant bypass for the 2019-Present RAM with 6.7L Cummins! Our patent pending design 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 AN fittings
  • Mounting hardware

Warranty:

  • 1 Year Limited Parts Warranty

Average quality, not as premium as expected
Color: Beige
Before buying, I thought it would be a thick, glossy satin ribbon. After receiving it, I found the material is rather thin and the texture feels quite ordinary. When used for gift wrapping, it looks a bit cheap and doesn’t match the effect shown in the pictures.

Print quality is inconsistent
Color: Pink
Some labels come out okay, others look blurry or faded, especially with smaller fonts. For decorative ribbons, details matter, and this just isn’t reliable.

Edges fray easily after cutting
Color: Beige
After cutting the ribbon, the edges tend to fray quite easily. This makes it less attractive when tying bows or using it for decoration, and it requires extra handling, which is not very convenient.

Inconsistent printing quality
Color: Beige
Sometimes the printed text has unclear edges, especially with small fonts, which look a bit blurry. When used for delicate decorations, it doesn’t look very professional.
