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.
quotes.
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 )
- Raise and safely support the vehicle.
- Remove the right front wheel.
- Remove the splash shield.
- Remove the drive belt.
- Hold the pulley with the holder handle (A) and holder attachment (B).
- 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)
- Install the drive belt.
- Install the splash shield.
- 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)
