Bill,
The bypass port that Bobby made reference to is directly below where the thermostat
resides in the housing.......This port is uncovered while the engine is warming up to
operating temp and allows the coolant to bypass the radiator........When the thermostat
opens the bottom part of the thermostat closes off this port and forces all the coolant
through the radiator.......If you are not using the thermostat then this port must be plugged.....
Different methods have been used by the group but most have threaded this port for
a 1/2 inch pipe plug........This port being open without using a thermostat will cause temps
to run high.........FWIW

-------------- Original message from "Bill Bradburry" <bbradburry@bellsouth.net>: --------------
I didn’t really modify the thermostat housing…I replaced it. I fabricated a plate out of ½” aluminum, drilled two holes in it to accommodate two 1 ¼” aluminum tubes which are JB welded in place and bolted it in place of the thermostat housing.
The thermostat housing is a pretty complicated looking outfit for the Renesis. I have considered using it. Does anyone know what the purposes of all the outlet tubes are?
Thanks,
Bill B

Bill,
When you modified the thermostat housing did you plug the bypass?
