try bleeding the system

when car is cold,
1) take out the 10mm bolt in the water neck that connects to the upper rad hose
2) open the rad and fill with water until it starts to come out the hole in the water neck, put the bolt back and tighten
3) top off the rad and close it

the system takes alot of water...you don't need to use coolant unless you think there is a chance the water will freeze in there

still could have a HG issue, but keeping the water full will get you further between overheatings if you don't want to do the HG right away
