MasterA few things -
First check the temperature of the cooling system under the hood. If the hoses at the heater core are not hot - it could be a thermostat sticking open. If one hose is hot and the other isn't - it could be a restricted heater core. If all is hot, then you could have a problem inside the vehicle with the doors that open and close the hot and cold air flow.Flag ThisLike0 -

RookieHelp I have '96 4.6 The engine and heat seem to take a long time to heat up and the heat works intermitantly. When the heat starts working the temp of the engine will finally go up to normal. also I was watching the reservoir and the just as the coolant was over flowing it started going down in big glugs, large air bubbles came up and, the coolant level dropped, and reseroir looked empy. At that point everything seemed normal on my dash guages. HELP

Have you done any repairs to your cooling system very recently?
If so, you could have an air pocket in your cooling system that needs bled.
If not, i'm not entirely sure - a good diagnosis on site is in order.
