So the other day the low coolant light came on and shut off 15 sec later. Got home coolant was a little low put more in it. Then driving again today the light would come on and off randomly and i noticed my Temp would go up to 185 then drop back down to 180 where it usually is. It did this a couple times too. Would this indicate air in the system? I personly replaced the lim gasket and thermostat probably 8 months ago. There is also no coolant around elbows or on the ground either.
