yes, i did buy it a month ago and have already put 2k into replacing everything to new. i figured it was either stuck open or not there, ive had to use that trick too. im going with the clutch for now because its alot cheaper than a radiator, and it seems to be the concensus. the only time it overheats is at idle or very low speeds, then back to normal.

 

Re-reading your post it does seem to be an airflow issue and that does point to the fan clutch.....You do have the factory shroud still in place?

Actually Just changed it out now and I'm letting the truck idle now. Everything was how it was factory, so the only thing I have to do now is hope it worked and change the tstat

 

so you got a new fan clutch? where did ya get it? and how much ya pay? if you dont mind me askin...

 

Didn't seem to overheat at idle but I'll give a test later on the hill where it always does it. I know everyone said to go oem but I got this one from advance auto for 29 bucks on special so I figured I'd give it a shot for so cheap. Seems to be ok built, it's a imperial brand.

 

for the future. if you need a new oem fan clutch... i know where to get em for 63$ shipped to yer door. its where i go mine.

 

Did you fix the problem? My truck runs just under half on the temp gauge, but since I rebuilt it and bored it 1mm over it's been overheating when I'm offroad, stop and go traffic, or extended idling. Once I get moving again it goes down to normal.

I just changed my thermostat but the dumbass at autozone told me it was the only one they had. Go back the next day and find out they have 4, and don't know which temp it is. I think it's the oem temp though. Also did the CTS recently, and finishing the "super cleaner" cooling system flush.

 

Might be worth checking out the fan clutch:

That is what cools the engine when moving slow enough that there is no air naturally flowing through the radiator.

 

Thats what I was thinking too. I checked it at operating temp today and I could slow it down with little and even spin it backwards while the engine is running. I'm going to take it off and try adding oil and see what happens.
