Hi there. From the description you have given, your vehicle’s heater not working is not the only problem that needs to be addressed. Chances are the sealer could have plugged the heater core. A cooling system flush could correct the inoperative heater but could also start the gasket’s leaking again. It could be that the engine’s thermostat is stuck open not allowing the engine to get to operating temperature.

I recommend having your vehicle’s not putting out warm heat be diagnosed and repaired by a certified technician, such as one from YourMechanic.
