Overheating

My 996 runs hotter than I believe it should.  The needle is about 1/4 of an inch passed the 180.  I have a new water pump and thermostat.  I have cleaned both radiators if debris.  I have relieved that pressure with the release valve.  The overheating light came on once after a run while backing into my garage.  Any suggestions.

Are both of  your fans coming on?  Manually turn on your AC and check if the fans are running low speed on both sides.  Are your fans running on high speed when it heats up?

Please check the fans as mentioned above. Possibly the resistor if the are not working which is easy to replace with a cheap diy fix.

You may have an air pocket in the system from changing the water pump and thermostat.

There are multiple functions of the temp gauge light, so to say it came on it could be low coolant level.  Check your owners manual for the various conditions that set off the temp gauge light.  If the rad fans are operational, then like JFP said, you could have an air pocket.  Make sure your coolant level in the expansion tank is full, then manually lift the wire bail thing on the expansion tank and drive several heat/cool cycles to bleed out any air.  Turn on the heater full blast as well.  That will cycle coolant through the heater core as well.
