After a month of being sick I am ready to install this new thermostat. In my last post on this I was told to orient the steam vent to the top of the thermostat housing but it won't go any further than the 11 or 1 o'clock position and the brass vent is locked and has no movement, this doesn't seem right. Is this the "clicking" in place motorcraft is talking about. Want to get this right, I am so sick of doing every job on this thing 2 or 3 times. Thanks for any and all input.
