Most likely there is air in the cooling system or it could be a bad thermostat.... Your temperature gauge could also be malfunctioning from a bad ground -- Happens allot! Try to purge your cooling system of air or bring it to a mechanic that gives free diagnostics and ask what is going on.

1)Check your fluid level. 2)make sure fans are coming on. Follow up with your answers. Does the gauge go do while driving, then up at still idle?
