hey mate

im tryin to do this fan change, although when i was removing the nuts on the bolts the whole lot spun and i can't get to the head of the bolts on the back due to the water pump, i am unable to get the rattle gun on it to spin through it off. i have also tried the usual pliers and nut and other techniques, but dont want to ruin the thread and i dont wan't to cut out the bolts incase i cant remove them.

have you got any ideas on how to get the nuts off.

thanks for your time

@msefatt You may have to turn the fan, so that the bolts rotate to the top where you can get at them again.

@1aauto, Sorry i explained it wrong, the bolts are spinning and i can't reach the bolts head so when i spin the nut it spins the bolt also,i have tried my hardest to hold the bolt and undo the nut, it didnt work

@msefatt You would have to find a way to sneak a wrench or something in there to hole the nut from spinning so that you could loosen the bolt.

There 2 points you failed to mention, #1-if there is alot of dirt and looks like grease around the temp spring, it probably is starting to leak. #2- Not all water pumps have studs sticking out and usenuts to hold the fan on, some use bolts. On the ones using bolts I have found it easier after loosening the bolts remove the belt because if the pulley  get out of alignment from the holes in the waterpump shaft it is harder to see the holes for the bolts when installing, belt off makes easier

@surrynet Thanks for the additional tips!

Another tip I Learned years ago, when installing nuts on studs that hold fan on and not much room to spin the nuts on do this : take a flat shoe lace, tape it to one of the flat sides of the nut using small piece of tape. If the nut turns on clockwise, wrap the shoe lace around the nut clockwise like you would with a yo-yo. Hold nut against the stud with one finger and with the other hand gently pull the shoe lace like starting a weedeater, the nut will spin itself on, works every time.
