My fan clutch finally crapped-out, so I need to replace it but can't get the nut loose. I know what the process is, but my nut has been working itself tight for 101,000 miles. Any helpful hints anyone else has on getting that sucker loose? Thanks |

Make sure that you're turning it the right way!
If your truck has a single serp. belt, they fan is removed by turning the nut CCW (when looking from the front). This got me when I removed my fan since I assumed that it was reverse threaded. If you are turning it in the right direction, try some PB Blaster, and maybe a strap wrench to hold the pulley.
Good luck - |

I just did this this weekend so maybe I can help:
Use the proper wrench size on the fan clutch nut (1 1/4") and then use a pair of large channel-locks on the visible stub of water pump pulley mount (it may help to take off the three bolts securing the water pump pulley) and then just heave opposite each other and it will come right off. Mine too had been on for 108K!
I tried shocking it off first, while the belts were still on, by hitting the wrench with a no-bounce, but it didn't work for me.
Also - sounds silly, but make sure you're going the right direction. The 3.9 v-belt engines have it come off clockwise and the 4.0 serpentine engines come off counter-clockwise.
Good Luck

hello all, with regard to this topic... I have a '98 SE and I must say that I've brought into the dealer more then 4 times already while still under warranty. all 4 times they say they've fixed it, however after a day of getting it back the fan kicks in more than it should my brother has a '95 and his has never had this issue. any suggestions as to why this is happening? |

Warren,
maybe the fan is viscous clutch is doing what it's supposed to when it supposed to and you have a termperature problem instead? Have they replaced the fan-clutch? If so, I would doubt you'd get two bad ones in a row, so would start checking engine temps and looking at what cooling system maintenance has been done/not done.

Thanks all for the advice. I was able to get the nut loose after letting it soak overnight with Liquid Wrench. I did find the nut to be 36mm instead of 1-1/4", but was able to accomodate with a large adjustable crescent wrench. A strap wrench holding the pulley wheel worked quite well, actually. |

thanks for the response Bill, you know I don't know if they checked to see if my temps are in the norm, all they would say is that they replaced the fan should be fine now... you know dealers as long as they get their money they don't really care after that.

hi guys, I'm a bit green in this dept. but if the thermostat is replacable/fixable, where is it located? and how do you take it apart for repair?

The way to fix a thermostat is to buy a new one. They fail when their wax pellet looses it's elasticity and thermal expansion/contraction ability, and are not repairable.
Where the top radiator hose goes into the engine, the thermostat is located where that housing bolts to the intake manifold. Drain the coolant down below the level of the thermostat, remove the cooling hose at the thermostat housing, remove the two bolts, and remove the housing+thermostat (if it doesn't fall out on it's own). Pay attention to which way it's inserted in the engine. Takes a new gasket on reassembly, and make sure the little jiggle pin is atop. |

thanks Jon, one more question... where can I buy the parts? are they available at Pep Boys, Kragen or do I have to get it through the Dealer? |

Well...
NAPA sells the thermostat; it's a Beck-Arnley part, but it's been a while since I replaced mine, so I can't remember the part #... 143-074 or something? It was about $7.99. They didn't have the gasket. I got mine from my dealer for about $1.39. And you can always mail order everything from places like Rovers North, Atlantic British, roverconnection.com, and XK's Unlimited (they're cheapest). |

i would recommend not getting the cheaper paper gasket and try and get the metal/rubber gasket that comes with the truck. or if the one you have is in good shape use it again. i had a paper one fail that is the only reason for me saying this. |
