Thanks Rob & Terry for your input on my last "hub" question.

Rob......update on the rad/coolant/temp issue.....so, before work on the cooling system (old coolant, old leaking water pump, puking rad coolant after shutdown, temp gauge always fogging up and no thermostat whatsoever, the temp gauge never read over 140 F.)
Now, after professionally flushing the rad, adding in a 160 F thermostat and a new 3 pulley water pump and adding new coolant at about 60/40 coolant to water ratio regardless how the jeep is driven, the temp gauge rarely fogs up, the rad never pukes coolant anymore, however, the temp gauge now always just gets a hair past 180 F (never any higher)...why? and what may be the issue?....bad thermostat?.....bad temp gauge? or bad sender?....just after shutdown the rad coolant temp at the rad cap always reads about 155-160 F.
Is the thermostat not opening?

Thanks,
