would try bleeding your engine. sounds like a airlock. follow both the upper and lower hoses to the engine. look at where they run in and there should be a bleeder valve that you open with a screwdriver. warm up the engine and slowly open the valve till all if any air comes out.

sounds like you did not refill the system properly. right above the thermostat housing is a single screw with copper washer. you need to take this screw out before re-filling cooling system. that screw allows air to escape from the engine while re-filling coolant. you have an air pocket in system.
this is because your vehical is heated by hot coolant flowing through a small radiator the blower motor blows air through this and out your vents and gives u heat but unless you drive your vehical the coolant will not build heat for quite a period of time there for your interior will not warm up as quick
My 2005 Nissan Sentra 1.8s with 55,000 mi. blows cold air from the heater. Coolant not circulating in engine. Lower hose stays cool to touch. Both heater hoses cold. Changed thermostat - didn't fix it. Coolant not leaking or dirty. None in oil - no oil in radiator. Changed worn water pump belt - pump spins freely with no noise or resistance. Cooling fans come on after warm-up. Temperature gauge stays in normal range then jumps to hot and back again. Coolant good to 10 below - didn't freeze here yet. No other problems or repairs to car. Afraid to drive and make worse. Help!

My 05 sentra with 79k miles heat will warm up and then get cold after a mile of driving, we have tried to get the air pocket out, the mechanic stated he thought it could be a blown head gasket, another mechanic said it was a bad heater core. Any advice would be appreciated.
i check coolant so that is not it
