This is the 2nd vette I've owned (earlier one was a '69) - had it for 8 years and never, never had a problem with the car! What the heck is going on? Have owned this vette for 4 years -bought from a reliable dealer. But....now...car heating up to 240 (in 10 min) again. Billowing steam out through all vents. And on top of that..I just put in a new heater core 10 months ago. I'll call my old boyfriend who worked on the '69 before I go back to the people who sold me this whatever you want to call it! Tried replacing sensor for fan on car...that wasn't it. Thermostat good. Geez! I love my vette....someone tell me why I have to replace this again!! Am I going have to do this every 10 months???? I don't think so!

I agree that you may have a blown head gasket. However, it's odd that increased pressure in the cooling system is not blowing the rubber radiator hoses. Are the radiator hoses covered with braided stainless steel or something similar? Usually a hose will blow before the heater core is damaged.
If you have rubber radiator/heater hoses and you're definitely getting steam from the defroster outlets, you may actually have just gotten a bad replacement heater core. It's a bummer for sure, but such things happen. Replace the core but check the car very carefully for any other problem that might be causing the cooling system to pressurize.

Truly sounds like you have a blown head gasket or cracked head. If it's heating up like that. The leak or crack allows the combustion chamers in the engine (usually just one) to pressurize the cooling system. This will push steam out of the radiator cap and also damage the heater core. Put your hand over the hole on the radiator where the cap goes when you first start it. If you feel some pressure, you know for sure. There's nothing you can do except to tear the engine down and fix it. Now this could also be a sticky thermostat so I'd replace the thermostat first. Good luck.

been there done that! Been around mechanics all my life . When this hap-ed to me i didn't have a clue. And was amazed when i found out the problem,had never heard of it. You can have a bad ground in your electronics. When this happens the systems ground into the fluids of your vehicle,interns deteraits the aluminum welds in the radiator and heater coil of your car. Amazing hu? Talk to Any radiator shop about this,thy will know,and can test your fluids for eclectic currants. Ten points?

Check for vibration or stress on the solder holding the pipes leading into the heater core.
