If i get in my car in the morning and go without warming it up it goes right to 195 then it goes down to 155ish again back and forth with the flexuating...Park, idle, temp goes to 195 and stays...nice scolding hot heat..get out upper and lower hose are both squeezable..no pressure building up?? No leaks, no blown head gaskets no cracks nothing?!?! DRIVING ME NUTS. Any suggestions would be appreciated
get another thermostat, new does not mean its good. get a high quality t stat.

I place these in boiling water and then remove heat see what temp it closes. repeat several times...must close at the spec temp..
