92 Ford Taurus 3.8 V6 overheating problem

I have a 92 Taurus that seems to be overheating. The Temp gauge will get up near the high end Hot. It seems to be intermitent. Sometimes it runs cool and sometimes hot. I have tried replacing the thermostat and running some radiator cleaner through the system. The coolant that I drained had lots of rusty orange in it. I had the head gaskets replaced about 2 years ago. The car has about 89000 miles on it.

Are these symtoms from a blocked radiator. What are my options? Is it hard to take the radiator out on this car and have it flow tested?
Can these radiators be rodded out?

I am not loosing any water. No oil in the water or water in the oil.
The fan runs when it gets hot.

Is the radiator fan operating on when it should? Under what circumstances does it overheat?

The fan seems to work fine. I wonder if the radiator is plugged.
Has anyone replace one of these? Would backflushing help?

Try cleaning the outside of the rad with a high pressure wand at a car wash.
Spray in between the condenser and the rad. Just wash the rad really good and see what happens.

The fan comes on when it should. I thought the problem happened only when I was in stop and go traffic but it happens when I am driving at about 35 mph also.

i gotten a 93 3.0 taurus, no you dont have a plastic impeller in the water pump like another poster suggested so you can fogret that.. if you have rusty water in the radiator then you probably have water in the system and not coolant... At that time that would make it run hot as the plain water boils over at 212 F whereas the 50/50 mix of coolant to water will go about
260 deg. before it boils over.. if you are interested in a new radiator they cost about $115 at www.radiators.com and alot of local places that sell wholesale radiators. But at the same time they are not worth figuratively trying to fix the plastic radiators.. they wanted $75 to work on mine.. a few dollars more and you get a new one... with a 92 taurus its about time for new hoses both upper and lower radiator hoses.... Next its four bolts to get the old radiator out and the two connections from the auto/trans cooler lines to the radiator and how about a new rad. cap just in case it blows its pressure before the 16 lbs. that it is suppose to hold,, mine would blow it at 4 lbs. of pressure ( Notwithstanding found this out with a test)....

no the 92 taurus dont have plastic ipmellers in the water pumps.. its all metal....
