A while back I flushed my cooling system, I thought I did everything correctly...opened the drain plug and drained the rad. Well after I filled it back up I noticed that it makes a bubbleing sound for about 30 seconds or so after start up. It also runs a little warmer then it used to. I've came to the conclusion that I have air traped in the system since a fellow 3.8 t-bird owner also stated that his car made the same sound, and it was traped air. Also my car seems to be useing coolent, I don't know where it's going. I thought It might be a blown HG but there's no signs (clean oil, no smoke, doesn''t overheat,just runs kinda warm) so the dissapering coolent kinda has me stumped. I think it is liked to the traped air some how. Anyone know where the coolent is going or how to get the air out of the cooling system??

There is a bolt that states, remove before you fill the rad to get the air out and its next to the tstat. after fillig replace the bolt and thats it.
