you need to use a long flat head screw driver and place it between two of the other studs and hold it while you loosen your nuts. do not remove them untill they have all been cracked loose. be careful you can get hurt.

How do i replace an idler pulley on a 02 xg350l

the 02 and the 05 are identical. There are TWO idler pullys ... one for the power steering, and the other for the AC compressor & alternator -- WHICH ONE? In any event, you'lll need to remove the right front wheel and the splash guard (10mm bolts) to access either of the pullys. Use 14mm wrench (or ratchet & socket) to loosen the appropriate pully (Pwr Steering has 14mm nut & two 14mm bolts), The other pully has one 14mm nut & one 14mm bolt.
Go to and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.

Need to replace just the belt for the ac on a 2000 doge caravan

there should by a small pully (called a tentioner) under the alternator pully, get a wrench that fits the nut in the middle and turn it counter clockwise this will loosen the belt to get it around the other pully. Ps. this is easier with two people, one to release tention and one to put the belt on.

Cooling Problem With My 97 S10 Blazer

Leave belt on, the fan clutch will loosen in the same direction that the fan turns while engine is running.There is a special wrench for these but, as a help to loosen it, with a heavy hammer and long chisel, place chisel blade near top of nut flat and strike firmly till it loosens in the direction the fan turns. This method is really not recommended as it is a shock load the water pump is not made for.Use care not to hit strait into shaft center. Before replacing fan blade, what caused fan to hit shroud?? Fix that so it don't happen again!Good luck! Freezing and thawing in Michigan!

1990 cadillac deville need help water pump removal???

Water pump is located on the side with all the belts. Find the water pump pully and LOOSEN the bolts that keep the pully on the shaft of the water pump. Once they are LOOSEN remove the belt. Then you can remove the pully bolts the rest of the way. Pully MIGHT be stuck on there, a couple of taps should loosen it enough to where you can pop it off by hand. Now if I recall this vechile correctly, there MIGHT be another pully that will hinder you. It's just easier to take it off right away. It's right above the water pump. I BELIVE it's an idler pully. Dosn't do anything but to help keep the belt on it's correct path. There should be one bolt in the middle of this pully, undo the bolt and pully will pop off. Make sure you REMEMBER how it was on. So that you put it back on the right way. Then, there are 2 or 3 different sized bolts that keep the water pump on. Remove the bolts, one at a time, and make sure you REMEMBER where they went. If you remember now, it will save time guessing later. Ok, once you are sure that ALL the bolts are removed, you can try to pop off the pump. If it dosn't come by hand, use a screw driver to pry a corner up and then do the rest by hand. Once it's off, it's time to clean the motor side of the pump. See, on these cars it's not a complete pump like it use to be, it's a half pump. Meaning, when you look at one side you can see the fins that move the water. Anyways, when you are at the parts store, pick up some emery cloth. It's sort of like sand paper. Well, once the pump is off, use a razor blade and scrape off the silcone that's on the block. Then use the emery cloth to make is nice and clean getting all of it off. Once that's complete, put the new gasket on the pump and reinstall. Put all the bolts in BEFORE tighting them down. And when you do tighten them, do it by hand! Using an air tool will break the bolt or strip the threads in the alunimium block and then it has to go to a mechanic. Once all the bolts are tight fill up the reservor to check for leaks. Also go back over the bolts one more time and make sure all are tight. Doing this now, will save you headace later. Then put the rest of the things back on in the order you took them off. That's it exepct for bleeding the cooling system. I assume you know how to do this, if not, let me know.

The big nut spins counter clock wise. you have to put your pulley bolts back on and make sure they are tight. leave belt on so that you have more resistance to pull against when tring to loosen the nut put a bar inbetween the pulley bolts so it won't slip off and then loosen that big nut looking thing and you should have it from there. to the same thing in reverse order to install it
