Hello, I have tried to research this to no conclusive avail. I'm working on a 2004 Ram with the 4.7. I just got this motor back together after the famous head gasket failure. I am trying to find out where to clock the "jiggle" valve on the thermostat. I don't remember how the factory one was. The new one is at 1:30 , that's with the notch on the rubber gasket matching the receiver in the plastic housing. I've read they need to be at 12 and 6:00 position, I"m not really sure it even matters. I just remember a few years ago with a cheap thermostat it ran 200 to 210 even after bleeding, not long after that the head gasket started leaking and steaming from the exhaust. I don't want to go through all that again. Anybody have any input? And I did try to search this here also. Thanks..
