Fleece Performance Coolant Bypass Kit 07.5-12 Ram 6.7L Cummins
Description
Heat is the number one killer for most engines. This is especially true with the Ram 6.7L Cummins. The rear cylinders of the 6.7L Cummins suffer from a lack of coolant flow resulting in higher coolant temperatures. This can cause major problems such as excessive coolant pressure that can eventually blow out the external and internal freeze plugs in the block and head. The answer to this issue, the Fleece Coolant Bypass Kit.The Fleece Coolant Bypass Kit adds a secondary thermostat that works based on temperature instead of pressure like other brands. This solves the problem before pressure becomes an issue by ensuring consistent temperatures across all six cylinders. A unique feature that sets this kit apart is the front coolant bypass thermostat housing that incorporates a built in AN fitting instead of a coolant spacer block like other brands. This kit comes complete with black braided hose and AN O-ring fittings to ensure a leak free seal. This is one of the most important additions you make to improve the reliability and longevity your 6.7L Cummins

"Was pretty simple to put on. Had the help of a diesel mechanic. The only problem I ran into was fitting the part with the extra thermostat in between the firewall and the block. Other than that it was pretty easy."
Pretty intense install
"I have not installed this on my truck due to the fact it’s pretty intense if you plan on doing it with the engine in the truck. My truck is an 08 and has a big thick bracket thats attached to the back of the engine block and connects to the top of the transmission. I’m a little unsure about removing this bracket. When my truck needs a rebuild someday I will install this kit but it’s pretty intense to install."
Q&A
- Does this kit work with a fully deleted truck?
- That kit will work on the Cummins regardless if there is an EGR present or not.
