temp gauge bouncing???

ok replaced thermostat and cleaned the lugs on all the gauges andeverything reads right around 210 degrees wile out playing driving and even on these hot days...my problem is on the ride to work past few days when it got a lil chilly, i turned the heat on and it went from 210 to almost pegged, then back to 210 then a lil under normal then back to damn near pegged, it just jumps everywhere, and cant seem to figure that out but as soon as i turn heat off it goes back to normal and stays steady.....any thoughts?

Sounds like air in the system.

If it is air in the system, how do you remove that?

jack up the front of the vehicle or place it on ramps and open the radiator cap. start the engine and let it run until the t-stat opens. any air that is in the system will now escape through the open cap. allow it to run until all the bubbles run out. add coolant as necessary.

Make sure to run the heater while burping so any air pockets in the heater core are purged as well.
