I hate hot engines !!!

Verify you have at least 30* ignition timing at 2700 RPM.. this is a min. not a target

verify your crank pulley is larger than water pump pulley by a min of 15 %

V you have a working 180* T-stat and it is not being bypassed (rad cool until t-stat opens on start up)

I place fan sensor in rad to turn on fans if temp above 180* (this allows fans to cycle)

I have a manual fans on - dash switch so can turn on in traffic .... period

air / fuel ratio a little fat helps cool engine. lean mix runs hotter check what you have

you never specified when or how it was overheating... IE. only in traffic but cools at freeway speed or only when on the freeway or stop n go starts overheating and won't recover once she starts to get hot or ??????? GOOD LUCK be patient
