This was recommended to me and it worked. Just check if you have green or blue anti-freeze. This is for getting trapped air out. Mine was a combo of that and low fluid. After this, super hot heat again. Good luck
Regardless, it does sound like you have some air trapped in the system. What I would do is, when the engine is cold, top off the radiator, install the cap, and fill the reservoir to the "MAX" line. Jack the front end of the vehicle up as safely as you can; if you don't have a jack and jack stands, try finding a relatively steep hill and park with the nose facing upwards. Start the engine and set the front and rear heaters to the maximum hot positions. Run the engine between 2500-3000 RPM for at least 10-15 minutes, making sure there is good heat coming out of the vents before shutting it off. Shut the engine off and lower the vehicle (if applies) and check the level in the reservoir. Top off the reservoir, if necessary, and reinstall the reservoir cap. This process will usually work. If not, you may want to check the heater pump. This is a small electric pump that circulates the coolant through the heater cores. It mounts on a bracket bolted to the firewall on the driver's side of the engine, has two wires going to it and heater hoses connected to it.
