After starting my temp guage varies wildly up and down and cool air comes out of the heater vents no matter where the guage is. After a while the guage will settle down to it's normal position and hot air comes out the vent. Will a new thermostat fix it?

Hello Jerry, I am sure you made sure the radiator is full & no air is trapped in system. If it is full I dont think a thermosat will cure this problem. Sounds like air trapped in system. Make sure radiator & overflow jug is full to proper level.
Hope this helps,
