Question about 2004 Nissan Altima
Possibly/most likely, a restriction of some type to core or in core, more than likely corrosion internally. Cheapest & best thing to try is complete cooling system flush, & reverse flush, to move that out of there if it will come. If that fails, I would circulate C.L.R. through heater core to help remove any calcium etc deposits.
