Most likely air in the system. If the system is not properly bled, air will be trapped in the lowest point of the coolant system and can get trapped in the heater core. You need to run the engine with the radiator cap off till all the air is pushed out of the cooling system.
Most likely you have air trapped in your engine, particularly in the heater loop. You need to properly bleed the air out of your radiator cooling system. The hot and cold blasts of air coming from first hot water followed by air.
Read up on how to bleed air out of your radiator system. Some systems are very difficult to bleed.
If after doing a good bleed of the radiator system the problem returns, you may have a bad head gasket or other leak in your cooling system which is injecting air into the cooling system (radiator/water cooling system).
Automotive cooling system has no bleeder valve. Removing trapped air (bleeding) from the system is done by loosening the upper radiator hose with the engine running, and letting some coolant to ooze out. If the coolant coming out already has no bubbles with it, then you already expelled out the trapped air. Simply running the system with out the radiator cap will also do the trick.
I you believe the air trapped on your cooling system, just do this hints.
Run your engine for awhile ( about 3-5 minutes) . then turn off your engine, open your radiator cap ( please wait foe awhile if it is too hot). Top up the coolant on your radiator. Repeat above step. It will be OK! now.
If there is no indication of overheating, the check coolant light is probably triggered by a sensor indicating low coolant level. It's also possible that there is air trapped in the cooling system from when the water pump was replaced. Trapped air could cause the sensor to throw the trouble light. Bleed the air from the cooling system and see if the light goes out. You may have to clear the light after bleeding the system.
Look for bleeder valves somewhere on the top of the cooling system. If you see any use them to remove trapped air. Start the engine and slowly turn the screw to remove trapped air. If there are no bleeder screws then remove the radiator cap from a cool engine. Make sure the radiator is full. Start the engine and watch for escaping air bubbles. Keep the radiator full at all times. When the engine reaches close to full operating temperature and you see no more air bubbles escaping put the cap back on. You may have to do this one more time if you experience any more trapped air in the system. Just make sure to look closely for bleeder valves. They will look like tire valves with a cap.
if the cooling system is not clogged and the water pump is ok then there may be air trapped in system, bleed air from system if need be. if air is trapped in system you will not get any heat. start car let it run take cap off of coolant tank then find bleeder for the coolant system, open bleed screw and air may be trapped in system.make sure coolant is at a proper level. do not forget coolant tank cap when done.
sounds like your fan is not turning on, check that first. if there is air in your system you have a leak. you cant bleed the cooling system, you have to first recover the freon, preasurize it to see if you have a leak, if no leak vacuum the lines then add freon.
