It's probably the heater core that's sprung a leak.
Head gasket could be bad
Your air conditioner may be faulty if it is not dripping water.
The wrong anti-freeze could cause the water to freeze in the engine. The wrong anti-freeze could cause abnormal corrosion in the radiator.
heater core has a pinhole leak! Only shows when under pressure .remove and replace not good to breath antifreeze vapers!
It depends on if you see the antifreeze leaking or it is just disappearing. If it is just disappearing then a bad head gasket or cracked head may be the problem. The smoking could actually be vaporized antifreeze. If that is the case don't run it until you can get it fixed.
that's just wrong mate.
A Chevy Cavalier can use standard, all-purpose antifreeze, so it's unlikely that the wrong kind was put in. However, if it is not diluted properly and the antifreeze is mixed with more than 50 percent water, the engine can overheat under some circumstances.
Lack of antifreeze or wrong mix of antifreeze and water.
Defective water pump.
because something is wrong with the vehicle
the heater core could be stopped up, or could be low of antifreeze, or the thermostat could be stuck open
Probably a blown head gasket. Get a technician to look at it. If it is, it will be a major ordeal.
