..and I would like to add that true overheating is 9 out of 10 times caused
by things other than a clogged radiator core.

 Ignition timing is #1 Assure: that TDC really is TDC. That the advance is
working and "total" advance is obtained. That all cylinders are firing. That
the water pump is functional. That the fan belt is properly adjusted. That
the radiator has adequate expansion capacity. That wheels turn freely.
Mixture too lean. Too much antifreeze to water ratio. And others.

 If your cars temp rises when crawling through traffic but drops quickly
once under way then it is working as good as it gets without adding capacity
or aux. fans. If it seems hot but does not steam or dump coolant then it is
OK.
