Did the the closed to open cooling system swap. In the process I eliminated the regulator valve thing adjacent the heater core. But now she doesn't want to warm up. Any advice guys? Thanks all in advance!!

First of all, what did you replace?

Radiator, thermostat, hoses, overflow Reservoir. Thermostat was swapped out with a matching thermostat. 195 degrees.

I believe the regulator valve thing is the heater control valve, and is controlled by vacuum. It let's hot coolant enter the heater core, when you move the heater control slider to cool, it shuts the valve off to keep hot coolant from circulating in the heater core and cooking you and your passengers. If you eliminated this, how did your route your hoses?

Coolant level has stayed the same since swap. It has not fluctuated. Coolant does not seem to be moving in or out of the bottle.

What I was interested is the coolant level of the system. If a cooling system is too low on fluid, it will not move coolant through the heater core.

The next thing to do is grab the hoses when the engine is fully warm and see if the hoses are hot

Then I would say your lack of heat is due to a blend door problem. Make sure the temp control cable is attached and working properly. The lever for the blend door is located on the passenger side HVAC housing just beyond the console
