No, this is not normal, you have a problem. My similar problem turned 
out to be the thermoswitch which runs the fan. Basically then fan was 
only turning on intermittently even at very high temps, and it never ran 
at high speed.

When the car gets hot, check to see if the fan comes on and *stays* on.
The thermoswitch is located at the bottom of the radiator and will have 
two or three pins. If you short out 2 of the connectors in the wiring 
loom, it should run continuously.

There are plenty of other things that will cause overheating, but this 
is easy to check for, ancd solved it for me.

Hope this helps...
