Freeze Coolant Bypass Kit for 2003-2007 Dodge Ram 5.9L 2007.5-2018 Cummins 6.7L

Item Features:
1The rear cylinders on the 5.9/6.7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures.
2.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.
3.Our coolant bypass kit adds a secondary thermostat, that unlike other brands, works based on temperature instead of excessive pressure.
4.This solves the problem before the pressure becomes an issue by ensuring consistent temperatures across all six cylinders.

Installation steps:
1. Drain the coolant from the radiator. Pull the antifreeze plug out of the rear engine.
Clean the surface of the plug hole with a scouring pad.
2. Assemble the braided hose to the thermostat housing. Dab the O-ring lightly.
Line up the housing with the rear hole, push it in and bolt it on.
3. Use a wrench to assemble the thermostat riser to the other end of the hose.
Rest the non-O-ring side of the block against the front thermostat.
4. Set stock thermostats on top and secure them with 3 bolts.
5. Adjust hose position to fit engine.
6. Install 2 hose retaining brackets or clips to secure the hose.
