Re: Rad fan dosen't run after engine off !

OK, which is it?  My '82 Coupe's radiator fan is shut off when the ignition
is shut off.  Why drain the battery just to cool the radiator?  This would
make sense on a turbo if water is still circulated to the turbo.  Don't
some turbo models have a special water pump for this?  In any case the engine
will just sit and cook because the water pump is not circulating coolant.
