it probably just needs more fluid in it . and it sucked a hose closed . What i do it fill the recovery tank pretty full , go drive around with a jug of coolant or water or mixed . wait fort he car to start getting hot like 240. Stop leave it running and open the radiotor cap slowly and also on a level surface . You should see and hear in your recovery tank bubbling like crazy and the level going down .But more than likely it needs coolant.

You have air trapped in the system. With the car cool, take the radiator cap off, start the car up and let the car start to warm up add more coolant as the level drops in the radiator.
Once the system is full, replace the radiator cap and continue to let the car get all the way warmed up then open the air bleeder valve to get the remainder of the air out.
I just went through this 2 months ago.

DO NOT open the radiator cap when the engine is hot.

Coolant in the system is above atmospheric pressure, which raises the boiling point of the coolant.

If the coolant is beyond the point at which it would boil at atmospheric pressure, removing the cap would reduce the pressure to atmospheric, but the coolant would still be so hot it would instantly boil (evidenced by steam)

If the coolant is only slightly above atmospheric boiling temp, it's not a huge deal. The further above it goes, the more dangerous removing the rad cap becomes. It's just bad practice to suggest to someone who may not understand completely.

A few things come to mind.
new water pump, new t-stat = no heat. In your first post u say its running hot. In your last post u say its at 195. Do u consider 195 to be running cold, hot, normal?
Even if u have blocked rad one of your heater hoses should be hot, water going into the heater core. It is possible to get a defective water pump. It is possible that a blockage could occur in the rad after doing a water pump depending on the condition of cooling system before hand. Maybe a lump of crud found its way into the rad.
After it's been running for 30 minutes how does lower rad hose feel compared to upper rad hose? Hang in ther and we will get u to an answer. Cool
