The conclusive evidence for fan clutch is this:
if the engine temperature begins to drop while the car is moving, you've got a bad fan clutch. Is the radiator clogged with deposits?

Overheating when driving

Sounds like the water pump fins aren't doing their job. I suggest changing the water pump. Been there, done that. Bad pump.

My truck is a 1999 silverado z71 w/ the 5.3. its got almost 200k miles on it and has always been reliable. Last week I was hualing a jeep home on a trailer and it got hot while driving in 100 degree heat w...

What this sounds like is a bad fan clutch. The people who flushed your radiator wanted money. The fan clutch is attatched to the water pump and fan. You can borrow the wrenches you need from most auto parts stores. The fan clutch runs about $60 and you can get the one for systems with a tow package which will aide in keeping the truck cool during heavy towing operations. When you go to install the fan clutch to the pump, give it a couple turns and then start the engine. The turning of the engine will spin and lock the fan clutch right into place so you do not need the wrenches at that point. Just for removal. Let me know if you need anything else.

Replaced waterpump, still overheating lights comes on

Check to see if there is water in the oil...If there is water in the oil then it could have a head gasket problem..Did you ever replace the thermostat? If it is stuck then it would also cause overheating...Excessive exhaust backpressure because of a clogged catalytic converter could also cause overheating..Also check belt tension and condition. A loose belt that slips may prevent the water pump from circulating coolant fast enough and/or the fan from turning fast for proper cooling...Another thing it could be is a faulty Water pump -- Any wobble in the pump shaft or seepage would call for replacement. In some instances, a pump can cause an engine to overheat if the impeller vanes are badly eroded due to corrosion or if the impeller has come loose from the shaft. The wrong pump may also cause an engine to overheat. Some engines with serpentine drive belts require a special water pump that turns in the opposite direction of those used on the same engine with ordinary V-belts... Also check the Fan -- With mechanical fans, most overheating problems are caused by a faulty fan clutch, though a missing fan shroud can reduce the fan's cooling effectiveness by as much as 50% (depending on the fan's distance from the radiator) which may be enough to cause the engine to overheat in hot weather or when working hard.

Car is overheating and not blowing hot air.

if your not losing coolant its either a blockage or bad waterpump and more than likely its the water pump

2001 chevrolet pickup v6 overheating after changing waterpump

If you are not getting heat now, it's because you have an air lock in the system. sometimes it can be difficult to burp the system. try turning the heater on high in the defrost position. run your vehicle with the rad cap off and keep the engine running at about 1500 rpm. That should give the waterpump enough momentom to purge the air through the engine. check around the heater hose area and around the thermostat area for any bleeder screws ( sometimes these vehicles will have 2 or 3 for ease of purging the air). hope this helps and if you need any other info please don't hesitate to write.
