HI Experts,
recently my alternator gone defective, it was replaced by mechanic and he removed the radiator . after he finished the work, i noticed the heater was not blowing hot air. mechanic pretty much rev up the engine and it started to blow out hot air,.
its been couple of days now, i am not getting hot air on idle.
when i rev up the engine and while driving, i am getting hot air. on idle , it throws cold air.
i been reading online and many people suggested they bleed out the air from radiator.
i try this process http://maxima.theowensfamily.com/tsb/NTB03-072.pdf , Lisle@ Spill Free Funnel.
but it just does not bleed any bubbles.

can someone please suggest what other method should i do .
i am holding 2004 nissan maxima.
thanks

 

No heat at idle is a classic symptom of low coolant level. The process in the link you posted should have worked, but evidently it didn't. It should have.

Try bleeding the air again but with this modified process. Raise only the driver's side wheel, kind of like you are changing the tire. See if you can get the bumper to be 12 inches higher than normal. Remove the radiator cap and start the car. Let the engine run until the thermostat opens and you have coolant flow in the radiator. Let the engine run for another 5 minutes to allow any trapped air to escape.

Be careful around the radiator filler neck because the air can also blow out some coolant and it will be hot.

Add coolant as necessary to keep the radiator tank maybe half filled during this time. When the 5 minutes is up, turn off the engine. Lower the car and fill the radiator all the way up and put the radiator cap on. Make sure that the overflow tank is full to the hot level.

After the engine has cooled, check the coolant level in the overflow tank. It should be down lower that it was. Fill to the cold level if necessary.
