If the cooling fans aren't working properly that can cause the overheating

If you need the A/C it means that the ambient temp is high.  If that is true then your fans have a Fan Module that tells them how much air the radiator needs to keep the engine from overheating.

If either of the fans are malfunctioning or the fan module isn't working right the car will overheat.  The Ford test for this is to hook your car to their computer and force the fans to top speed, if they don't do that the both fans need to be replaced.  The Ford computer also tells the Tech if the fan module is giving the right commands.

 

Do you smell coolant when you shut the car off, are you losing coolant? Your water pump or radiator could also be having problems.

If the radiator was replaced it is possible that something was overlooked when it was reassembled.

If everything was done right then you're going to have to find a shop that can test your fan and the module.

check other sites on this forum   overheating   overheated   stranded I think is another one all talk about similar issues... if a dealer replaced your fans they may have missed the obvious,  your fans and condenser may have been fine, the fan relay module has been a problem... question them, they'll probably give you the run around
