My fan clutch was stuck so I went and bought one from the Zone. I used the haynes manual. Well I was doing what they said, Hold the pulley bolt while using the special service tool, loosen the fan clutch nut. Well It didn't work and I tried forever. Any ideas on how to get this off?

all you need to do it put a big wrench( a big cresent fits them good) on the fan clutch, put a cheater pipe on it so it clears the fan and give it a whack with a hammer to break it free. I have done a few of those and thats all it has ever taken to get one off.

I went to autozone and got the sst and even put a breaker bar on it and still couldn't get it. I tried to hammer it but nothing. Plus the pulley wouldn't stay still enough.

Sorry for the long delay, I was away.

 

The manauls just shows the direction of the bolts.

 

But as you notice at the top of the service manual page I posted, you'll need the special wrench.

      Acceptably cheap tires?

      By Atlas · Posted

      Which one, the AT or AS?   Starfire is made by Cooper/Goodyear but at $85/tire I'd think I'd need to level-set my expectations that they may not even be round 😉 But you're saying they're decent?   I'm already into this thing $1506 in parts, fluids, etc. Totaled all my receipts today. $250 of that was replacing an EGR and MAP sensor that were probably fine, but I'm not going to return the parts since they've been installed. I'm cheap, but not that cheap. I use it, I keep it!   I may or may not make money if I sell the truck at this point, but, that wasn't really the point. And if I billed my time, I'd be hosed for real. My thought on the tires is I "might" put 1,000 miles on before selling it. I just don't want to put absolute junk on it, that doesn't do anyone any good. If the Solus solidly isn't junk, I'll definitely consider them.

      Is your l8t engine bay super dusty?

      By rjgvt · Posted

      I leave mine as is. I'm always a trip away from riding on unpaved roads. Dealer can clean it when they prep it after I trade it in for another new truck.

      I have these on two vehicles and love them. Pepper is one of them 😉

      4WD. Far as I know it came stock with P's and not LT's. Definitely planning to put P's on it, but stock is a 109 XL load rating so I should probably stick within that guideline.   No rebates on anything I can see at the moment. Discount Tire is offering $50 off, but Pep Boys is very competitive on price, and also carries all the off-brand stuff. Les Schwab always wants an arm/leg, but they do good work.   It still has the original spare. Goodyear Wrangler RT/S, thing looks like a tractor tire LOL!! How times have changed.

      2020 Sierra 2500 windows rolling down

      By JohnRoy · Posted

      2020 Sierra 2500 HD (base model) gas engine 4wd.    All 4 windows roll down on their own. Happens somewhat randomly after stop and engine off - when engine turned off, when walking away from vehicle before or after locks activated. Pulled the window fuse F14 Instrument Panel Fuse Block Right; the driver's side still activates from driver's side door panel; passenger and back seat windows activate from local switches on their doors but not from driver's side group of switches. Power mirrors don't activate with fuse removed either (same fuse for both circuits). Problem not solved.    How can they even activate with fuse removed but they are all still opening and can control from each door?  When they open on their own, I can shut them from the switch in each door, but they don't stay closed.    Seems to be activated somehow with key fob; something bumping the key fob in my pocket or just handling - removed key fob and took it far enough away and now the windows stay closed. Replaced key fob batty just in case, no change.    Sounds like some kind of wiring short or maybe electronics. Dealer will first replace electronic control module without checking anything else and I anticipate problem will still exist since their troubleshooting skills are limited to "do whatever the computer says".  In any case, keyfob seems to be activating the circuitry.    Surely I'm not the only one with this issue, but I can't find anything related on the site. What do yall think?   JohnRoy
