My fan shroud covers the entire radiator and my fan blades are completely covered by the shroud.

Another thing to check out would be the clutch fan if it's been replaced before.
There is 3 different clutches available, standard, heavy duty and severe duty(trucks).
Cars with big blocks use the heavy duty ones. If it has the standard duty one, this can cause it to run hot. Some people have used the one for trucks, but it is alittle noisier than the heavy duty one. It's one more thing to check out.
Good luck!

How can I tell if the fan clutch is bad?

Two things... thermostat? What temperature is it? Could it be stuck open or closed? And, what condition are the hoses in? They might collapse when it gets hot.

Any luck yet ?

Grab a hold of the fan blades, engine off of course and try to spin the fan, should spin but should have resistance. Also try to move a blade front to back, look for worn out bearings in the clutch assembly. Open the hood when the engine is cold. Start it up and you should hear the fan 'roar' for a second or two. If it's engaging properly when the engine gets hot you should also be able to hear a change in the amount of noise from the fan. Let the engine idle and get hot, should hear when the clutch engages.

If it spins easily by hand or you don't hear it engage it needs to be replaced. Hayden 2747 HD clutch is the best choice.

What type of fan? Is it a stock 7 blade fan? Carpoor brought up a good point. The lower hose can collapse when hot if it doesn't have a spring inside to keep it in shape. If the the thermostat was stuck closed the engine temp should continue to climb from the time you start it until it's way overheated. That doesn't mean the thermostat couldn't be bad, not opening and closing as it should. Stuck open, that won't cause a problem, except the engine might never come up to temp. It's a myth that stuck open or no thermostat doesn't allow the coolant to stay in the engine long enough to cool it. It just doesn't work that way. The more cool water you can force through the engine the more it will cool. They make high volume water pumps for engines that have a cooling problem, more cool water, lower temps.

Good info. I appreciate the help. I have been working alot and have not had time to dig into it anymore. I will in a week after several business trips this next week. The motor warms at a normal rate when air is warm or cold. Temp usually stays around 200-220 even at stops unless you get caught at a long light then it climbs. I check the fan clutch, replace thermostat (just incase), and check for the spring. I know the hoses are in good shape.

Ok, I do have the springs in the upper and lower radiator hoses. I also do have the stock 7 blade fan. It does spin freely but has some resistance. It will turn about two blade widths. I do however have some play in the clutch if I try to move the fan in a motion from the radiator to the motor.

May be time to just go ahead and replace the clutch if there is play in the bearings. The Hayden 2747 clutch can be picked up at most auto parts stores. A rad flush may help also. Since you're in Tx, you don't need to use much antifreeze, mostly distilled water. Good luck.

Thanks, I'll see what I can find.
