Re: Heater Issues
The temperature gauge should slowly increase until it hits the "R" in normal, and then stay there.
After that, it could be a few possibilities. There is a bleeder bolt to remove air from system(remove bolt, fill to top,squeeze upper hose,fill to top), Fan malfunction, clogged system + heater core that needs flushed, thermostat needs replaced or was installed incorrectly.
Good luck with it, hope dats some help-
