What Max says here is true.    I suggest if your A is overheating you  
refer to the wealth of information at Barney Gaylords site:

Personally,  first check your actually temperature with a  
thermometer.  You can easily open your radiator since it is not a  
sealed system.  (use a rag, it is still hot!) Most gauges are  
incorrect.  I run a blanking plate with themostat, (essential for hot  
weather, harder to warm up in cold) and I supplement cooling with an  
electric fan (I still have my fan blades. there is nothing wrong with  
using both).   In really hot weather the electric works well.

I also have my original radiator which has never been soldered shut  
by a radiator shop.
