How do you replace the thermostat located on a 2002 Chevy Impala?
pain in the ass, trustme..
every other car I've owned has taken me 5 minutes to change thermostat
a thermostat costs $5.00
usually located where the top radiator hose connects to engine
for the Chevy impala several parts are on top of thermostat
throttle body, intake hose, even the fuel regulater gets in the way.
take it to a mechanic...
on the 3.8 its easy to get to just 2 10mm bolts
