No engine stated, so any help will be wrong, !!!!!!
V6? we cant open hood and look, so we are blind as bats. here.

bad input nets bad output , just like a computer.

i dont think its LHT. left hand treads.
its either rusty,
or last guy used red loctite and needs 300F heat to get IT, soft.
or your not trying up to 150fl-lbs of reverse torque.
my damper is at 100/ft/lbs
and will take way more to break free (no locktite)
my guess 2 is this is a slush pump car, a A/T tranny?
and as such , you cant lock the M/t in 5th gear?
sure, and the FSM shows what to do , to get it off for A/Ts
some engines, have special tool.
and or a pulley locking device. (home made works, made many)
some guys just use impact gun and strip the treads out of the crank
and the new FSMs all say, (DONT DO THAT, exactly)
in a shop the dork that does that , just calls you and say, hey buddy
your crankshaft is wrecked, (dont let them touch your engine)

btw l, read the fsm.
and all words for the UNSAID actions you are taking.
here is one , just to scare you.
Reprogram the crankshaft position (CKP) pattern. Run the engine until the operating temperature reaches 176 degree. With the engine stopped clear the CKP pattern. Turn the ignition switch OFF. Turn the ignition switch ON and wait thirty seconds.
Check PULSAR F/B LEARN in the data list with the HDS. If not complete repeat the procedure. If complete, road test the vehicle on a level surface. Decelerate the engine speed of 5000 rpm to 3000 rpm. If equipped with automatic transaxle use two Drive positions. If equipped with manual transaxle use first gear.
see, may be the stuck bolt is a blessing,

here i will quote the pulley page for the 3.0L
just to show what a pain A/T cars are. (unsaid tranny )

  1. Raise and safely support the vehicle.
  2. Remove the right front wheel.
  3. Remove the splash shield.
  4. Remove the drive belt.
  5. Hold the pulley with the holder handle (A) and holder attachment (B).
  6. Remove the bolt with a heavy duty 19 mm socket (C) and breaker bar, then remove the crankshaft pulley.
7- clean the crankshaft pulleys (A), crankshaft (B), bolt (C), and washer (D). Lubricate with new engine oil as shown.
Install the crankshaft pulley, and tighten the bolt, as follows. Do not use an impact wrench.
  • Hold the pulley with the holder handle (A) and holder attachment (B), then tighten the bolt to 47 ft. lbs. (64 Nm) with a torque wrench and 19 mm socket (C)
  • Mark (D) the bolt head and crankshaft pulley as shown, then tighten the bolt an additional 60 ? (The mark on the bolt head should line up with the mark on the crankshaft pulley)

  1. Install the drive belt.
  2. Install the splash shield.
  3. Install the right front wheel.

note carefully this bolt is not set to a final torque,
it uses base plus angle.
id use a new bolt. (im savvy and hate buying new crank shafts)

SOURCE: replacing timing belt and/or water pump

i can answer part of that... have someone put pressure hard on the serpentine belt while you turn the bolt.... likewise if you have access to the timing belt tho i would be careful with that so the timing does not shift. after you get the bolt out you will need a puller for it too. carefull as well when you install the new one to match up the groove on the crankshaft with the pully or you'll never have the timing right.

Make sure you check timing and the belt. if it spun don't risk putting it back on. Hope you got a new key. TIMING is important so you don't stick a valve through the top of your piston

SOURCE: is the 3/4 inch bolt that is on the bottom pulley

Bolt on the pulley is NOT reverse thread, but you will need to apply heat with a torch kit (oxy/acetlyene), and an impact gun to get the bolt off. If you plan on doing a job like this, I would highly recommend a good repair manual to aid you during this reapir. Even I use repair manuals when ever I perform a big job like this, ya can't remember it all.

SOURCE: cant loosen bolt that holds on the timing belt.

1. Almost every bolt on the end of any shaft has left-handed threads. You turn it RIGHT to loosen.

2. I have used a chain wrench whenever I have replaced a water pump. It looks like a vise grip with a bicycle chain connected to it.

But if you use this, be sure to cushion the chain so as to prevent direct contact with precision surfaces. For this I have used rags or rubber hose sections.

Taurus crankshaft pulley

Yes you need a 'Harmonic Balance Puller' If you mean the centre bolt that holds the harmonic balancer to the crank. No not reveresed. Can be removed by placing a socket on bolt head and using a long handle placed against chassis. Touch the starter key to loosen.

Removing harmonic balancer

First, you have to loosen the crank pulley center bolt. Best way is with an impact gun-bolt is very tight. If you have to use a breaker bar to loosen the bolt, you will have to devise a way to hold the crankshaft from turning backward while loosening it. One method is to remove the starter and wedge a piece of wood against the flywheel, preventing it from turning, while you are loosening the center bolt.
From the beginning: raise and block the side of car that the front of engine is towards. Remove the wheel and the inner fender splash shield. Remove the belts. Remove negative battery terminal, remove starter. Wedge the flywheel so it won't turn backward. Loosen and remove the center bolt. Some harmonic balancers will slide right off the crankshaft now, some are on very tight, if you can't wiggle it, tap it, and get it to move, then buy an inexpensive harmonic balancer removal puller, just a few bucks, easy to use, will save balancer from trying to hammer it off. All you need is enough room to mount up the puller to the balancer, and get the balancer moving off the crank.
Some engine lay outs there isn't enough room: then you really have to get creative, either lowering engine enough to get to pulley, or raising engine out. But most engines are positioned where the crank pulley can come off easily, with enough room to get the puller on.
The pulley may have a woodruff key in a slot on the crankshaft, and a corresponding notch on the pulley, for proper positioning of the pulley to crank. Don't lose the woodruff key.

Need to replace the harmonic balancer in a 1994 isuzu rodeo. ( rwd, 3.2 ltr v.6 ). no success so far. is the main bolt reverse threaded? so far i have been attempting to turn it toward the passenger side,...

No, the bolt is not left handed. You do need to turn it counter-clockwise to loosen it. You're probably just spinning the engine when trying to loosen it. I use a 6" c-clamp and attach it behind the balancer in a way that the threaded shaft can lodge up against something so the engine can't turn. Then I use a 3 lb rubber mallet and hit the 1/2" drive rachet on the handle, or put a breaker bar on the end of it and work it loose that way. Once you get the bolt off, you will need to use a pulley puller to get the balancer off.

I have a 94 grand cherokee, the bearing went out on the upper idler pulley. my question is are these standard or reverse threads on the bolt holding the pulley on and any tips on breaking this bolt loose...

Your threads should be standard right hand. Don't worry about the pulley turning when you break the bolt loose. The bolt is isolated from the pulley by a bearing (the one that failed) so the two turn independent of one another.

Good luck.

Changing timing belt on 1987 toyota celica...i am having trouble removing the bolt on the pulley...what am i doing wrong??? Is it a reverse thread? is their a pin or lock washer?

That bolt is on very tight not reverse etc, just tight. Most shops use an air gun to remove it. If your engine turns clockwise (when you are facing pulley), sometimes you can use a solid breaker bar (not one with a flex will snap) and an impact socket braced against an immovable part of the chassis, install bb& socket then "bump" the ign key. The crank will turn but if braced properly, the bolt wont, but will loosen up. (take great care doing this...if bar & socket come loose they may fly up and injure you or some important engine part). I use this method a lot but you have to know it's not in any book!!!

Harmonic balancer

You'll have to remove the drive belt. Remove the lower pulley and large bolt in the center of the balancer. If the bolt is on really tight, remove a spark plug, move the piston to the bottom of the cylinder by turning the engine, stuff a bunch of rope in the spark plug hole, as much as you can. Now turn the engine counter-clockwise and the center bolt will break loose for you. Once the bolt has broken loose, rotate the engine clockwise again just enough to remove the rope. Remove the balancer bolt and get a balancer removal tool and pull the balancer off.
