Overheating?

[Sunkenkarma]

Just picked up a 93 hatch, d15b7. Just drove it home from douglasville, no problems, pulled up in my driveway, it was steaming a bit, pulled off the radiator cap, blew steam pretty intense for about a minute. Guy said the head gasket was recently changed, I doubt it, Im thinking its the headgasket though. Its not the thermostat, new radiator, new hoses etc, runs/drives perfect besides overheating. What else could it be? Want to get working on it ASAP.

why would you open the radiator cap when its still hot and under pressure? thats why it blew steam

I did it to relieve pressure, the overflow tank looked like it was about to explode.

On a side note, couldnt see it late night, but this radiator cap does not have the spring at the bottom of it, trying a new one now.
