Car over heats and idles

Asked by Sep 16, 2016 at 06:10 PM about the 2003 Chevrolet Impala Base

Question type: Maintenance & Repair

I have a 3400 2003 chevy Impala and it overheats within
5-10 minutes. I have changed the thermostat, water
pump, hoses, radiator is only a year old, belt is new along
with the idle pulley has coolant flushed it and bled it.
Again itll overheat within 5-10 minutes and it idles high in
park and neutral in drive and reverse it idles fine dont
know what it is. The carpet on the passenger floor is wet a
little bit.

Have you noticed any white smoke/steam exiting the exhaust tail pipe, or does oil look milky or coolant look milky, does your radiator sound like its boiling (actually exhaust)?
