Antifreeze leak

[Lee]

My 2010 Aveo stopped throwing heat so I replaced the thermostat yesterday. Seemed like a simple enough fix. Now today it’s spewing antifreeze all over and smoking. I check the connections, the hoses, the bolts, everything is tight like it should be. Any ideas what’s going on? I had no problems with Antifreeze before I fixed the thermostat.

So can this be anything other than something wrong with the work you did? You need to first locate exactly where the leak is coming from and then fix whatever the issue is.

make sure you bolted everything tight when u replaced the thermostat. I had my coolant leak badly on my 06 aveo. Replaced my radiator only to find that my waterpump was badly corroded. Looked like i removed a tumor off my car.
