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

Perfectly Fine and Inexpensive
This off-brand filter was $10 cheaper than the local auto store, nearly $20 cheaper than the dealership, and meets the original OEM requirements. My husband is an ASE certified master technician and does all of our car maintenance and repair work himself and purchasing this filter rather than getting the filter from the dealership or the local auto store saved us a good bit of money and it is the same quality. Just make sure that the OEM number is correct for your vehicle and you have nothing to worry about.

Easy to install
Very easy to install this engine filter and checking the compatibility with my car was super easy too. I took me about 5 minutes to look up, learn, and install this. Loved that I saved money by installing it myself instead of getting overcharged but the shop. Works for a 2017 Honda Fit.
