Re: Strange over heating issue
My 2000 deville has been over heating. I have changed the radiator, water pump, cap & thermostat. Now it only overheats when I am driving it. I can let it idle in the driveway for half an hour and it never goes past half way. Is there anything that you can think of that would cause this?
I would also like to know how much of a flow I should be getting from the purge line.
Thanks in advance for all your help.

idling puts no load/strain on the engine -
so it doesn't take much to cool it -

blocked airflow -
if the AC condenser is dirty -
it could be restricting airflow -
at speeds below 30 -
the electric cooling fans deliver the airflow -
be sure they are working properly -
if neither the condenser or cooling fans are the problem -
do a BLOCK TEST -
to - HOPEFULLY - rule out a failed head gasket -
I would also like to know
how much of a flow I should be getting from the purge line.
should just be a constant - gentle flow -
