12v water bypass kit – Improve coolant flow to Cyl #6

Improves coolant flow to  the rear cylinder  # 6 reducing the chances of piston scuffing due to higher temperatures caused by choke point/ less flow in  the standard cooling system.

This kit also eliminates the possibility of blowing the rear welsh plug, this can occur if the engine has pump and performance upgrades producing more heat and higher RPM.

Installation of this kit involves removing the rear freeze/welsh plug from the block and bolting the included plate with o-ring over it  and then running a 5/8 ID coolant hose to the heater core return line.

Install the rear plate & o-ring , then using heater hose, plumb the hose into the heater core return line (the hose that leads down towards the oil filter).

On some trucks, you may need to grind the bottom of plate to allow it to clear the bell housing.
