Fluctuations temp gauge and heat.

[LPKAUTZ]

Been having problems with fluctuating temperature gauge and heat coming out of
Outlets. The gauge goes from normal to almost over heat, then goes down to normal again. Have replaced thermostat and heat sender along with water pump. No change in actions of heat gauge and temp of air at vents.
ANY HELP would be appreciated.

Welcome to the forum. Make sure all the air is bled out of the cooling system.

Any hints on bleeding the air out? Have tried several things,
With no results.
