Fleece Performance Coolant Bypass Kit - 07.5-12 RAM Cummins 6.7L

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
