hey guys. I had my radiator, along with a bunch of other things replaced a few months ago and now that the cold weather is here I come to find out that the heat barely works. car doesn't over heat though. when I remote start the car it just blows out cold air. once I start driving I get a little hot air, but only to an extent. I cannot turn the heat past fan speed 3 other wise it constantly blows out cold air. does anyone know what would cause this? I'm assuming it's an air pocket. any help is greatly appreciated

 

Sounds like you're on to the correct issue. Bleed the system to get rid of the air and you should be good to go.

 

I just fix this problem on my G coupe (NY, NY)

PROCESS TOOK ABOUT 1hr
-Open the radiator cap, stick a funnel in there make sure its a tight fit ( i used electric tape and wrap the mouth/neck of the funnel.
-Start the G up.
-The coolant in the radiator will drop add coolant to the funnel about 1/2 full.
-There s a bleeder valve for the coolant where the fire wall is located side on the battery (passenger).
You will need a phillips screw driver.
Now loosen the bleeder valve about 3/4 NOT ALL THE WAY. You shoud see and hear air as well as coolant/bubbles coming out.
-turn on the heat all the way on high to 90 degrees. Let the air blow on the face. It will blow cold air.
You will see the coolant you added in the funnel drop, just keep adding coolant. Soon the the air blowing will turn hot.
TIP:
I had my bro rev up to 2000 rpm on park. and I added coolant to the funnel to speed up the process.
My G was on a flat/level surface didnt had to jack it up. When you let go of the gas pedal drop the RPM slowly or you will make a mess, coolant will splash where the funnel is

-When hot air blows continuous without having to rev up your good to go.
JUST remember to to tight back the bleeder valve and close the red cap.

Hope this help good luck!!!!!
