overheating.. fan clutch?? waterpump??

[tanFx4]

(this has happend a couple times) my truck over heats at low speeds.. if i drive 65 + ect will be around 210 (100 deg weather) i was driving 10mph and it ect got to 236.. as soon as i got to a faster speed it would cool down.. by the time i pulled into the drive way the ect was 222.. so popped the hood and the fan was spining in a very slow motion.. barely moving!! also.. at idel my ac wouldnt work and at low speeds it was slightly cool.. 65+ ac seems normal.. i let the truck sit for a couple days and i decided to start it and let it warm up.. it was blowing cool air at idle and i looked at the fan n it was moving fast.. the ect got to 196 at idle but mostly stayed around 192.. i didnt drive it.. any ideas??

Sure sounds like you need a fan clutch.

have your truck scanned if you get P0528 you need a new fan clutch. you might not get a cel to have the code. I had similar symptoms and replaced the fan clutch and it fixed the problem.

I check for codes n I got P0480 (cts says 'cooling fan 1 control circuit malfunction) n P0528 (cts says 'fan speed sensor circuit no signal)

Try plugging in your egr sensor and just letting it sit there on top of the motor. There have been reports that the fan would not work correctly unless the egr valve was plugged in. When I just had my egr unplugged I would randomly get the PO480 code. it's worth a shot though.

man thas not good for me to hear.. I have FCDP delete n they pull out the egr sensor n valve.. I have no place to plug mine in

You should still have the wire that the EGR plugs into, and that is all you have to do, is plug the EGR into the electrical connection that is there from the factory. Then you can either zip tie it up or let it lay on top of the motor, your choice. I don't have my truck with me right now or I would get a picture for you. But as long as you still have the physical egr valve you could plug it in and try because I don't think any brand of delete actually removes that wiring harness.

Don't have what?
The EGR valve or did someone chop your wiring harness to remove the plug?

Those are the exact codes I had a week ago, and it was a burnt fan clutch. I have still yet to hear the fan kick on though... As much as I toe, I've never heard it kick on...
