It never really "overheated" (boiling over all over the ground) but the temp guage damn near pegged. Maybe a air pocket in the system?
It is the dreaded vapor lock...our cars are reknowned for it....it can be super tough to burp the air out of the system.....good luck, be patient...there are lots of tried methods that you can search for. I would try the easiest first by draining at the thermostat (and replacing if it's been awhile). Then I would move on to using a hose through the upper radiator line

I hate to be the bearer of bad news but if the problem comes back you probably have a bad head gasket. I have a 90 Legacy, after replacing the radiator, timing belt, and water pump, still had the problem. After replacing the head gasket the problem stopped.
I don't know about "probably". I have had the problem many times...resulting from split hoses, cracked radiators, failed tranny cooler problems and a cheap t-fitting that broke...all caused the dreaded vapor lock.....all solved by burping the system...sometimes it was easy, sometimes it was a hellacious bitch. Defintely work on burping the system several times via several methods before replacing the head gasket

How much does it cost / how hard to diy / a head gasket ? What else would be prudent to do at the same time ?
