to take air outta system do as follows.....
when car is cold not ran all night, open radiator cap on radiator. slowly fill up radiator with collant&water (50/50) as needed till full.
then let car run with heat on high blast for 5-10 minutes. repace cap and should be good to go!
be careful as collant will get hot quick!
