My air condition belt broke in my 2001 Tahoe how can I tell if Compressor or Pulley is bad without belt?

if the ac belt doesn't involve anything other than the ac just leave it off for now and replace it at your leisure

You can also remove the a/c compressor and install a bypass pulley in its place. You can still use the standard belt this way, just run it to the bypass pulley instead of the a/c compressor. RockAuto has them at the link.

• Located front of engine, close to crank pulley
• press the helpful button and follow me on Fixya for more tips
• Insert the square tip of a 1/2-inch socket wrench into the square hole in the center of the serpentine belt's adjustment pulley. The adjustment pulley is the smallest pulley the belt wraps around.
• Pull the adjustment pulley toward the engine with the socket wrench to release the tension on the serpentine belt, then pull the belt off the air conditioning compressor's pulley.
• Remove the bolts which secure the air conditioning compressor to its mounting brackets with an open-end wrench, then position the compressor to the side of the engine compartment. Do not disturb the hoses that attach to the compressor.
• Pull the electrical connection off the crankshaft sensor.
• Remove the two bolts that secure the crankshaft sensor against the engine with an open-end wrench, then slide the sensor out of the engine.
• Slide the new crankshaft sensor into the engine, then install and tighten the sensor's two securing bolts with an open-end wrench.
• Press the electrical connection onto the crankshaft sensor.
• Position the air conditioning compressor against its mounting brackets, then install and tighten the compressor's bolts with an open-end wrench.
• Pull the serpentine belt's adjustment pulley toward the engine with the socket wrench, then position the belt onto the air compressor's pulley. write up found @ehow

How to Replace the Crankshaft Sensor in Ford 150 eHow

Usually pretty hard to find to get the right one. There might be one that fits your Stratus if a model was produced that had your same engine but without air conditioning. But keep in mind that that other model may have the other belt-driven accessories in a different location on the engine than yours. So the belt may or may not fit.

An alternative is to buy an "A/C Delete Pulley and Bracket" and install that in place of your compressor. It's just a free wheeling pulley set-up, then you can use the same belt without having to find a replacement size. Some company makes them, they probably have an application for the Stratus.

Odds are you can't. The ac compressor is mounted in the belt routing so it would need the pulley to keep the belt tight.
You can get a used compressor from a salvage yard and mount it in place of your old part if necessary. It will allow the belt to run even if it has no freon in the system.
There are a few vehicles that a replacement dummy pulley was designed for, but I am not aware of one for your vehicle. Usually if you try to run the belt without the compressor pulley, it will rub against something or not allow the belt to run in the right direction.

Use the same belt as the ac compressor will not work unless you turn it on. Disconnect the wire to the ac pulley clutch and the pulley just becomes an idler and you can get the standard belt anywhere.

Not really. I am not aware of that model being sold without ac.
So there would not be a belt and idler pulley used in place of the compressor.
The easiest way to fix it is to get a used compressor and put it on. You don't have to charge the ac for the pulley to work.

Lift the vehicle by using of jack.
Remove the engine support bracket.
Remove the power steering belt.Remove the air conditioning compressor belt.Remove the alternator belt
Remove the coolant pump pulley.
Remove the crankshaft pulley.
Remove the timing belt cover.
Move the timing belt tensioner pulley toward the coolant pump and temporarily secure it
.Remove the timing belt
Remove the camshaft from the camshaft sprocket
Remove the crankshaft sprocket and flange.
Remove the timing belt idler.
Remove the timing belt tensioner.

re install in reverse order. chances are the rod is bent but without breaking down the cylinder the only way to determine is to but a new belt on and see what happens. good luck.

It sounds like your air conditioning compressor or air conditioning clutches have gone bad the solution is to have rebuilt (or buy a rebuilt)air conditioning compressor. Do not attempt to work on thr compressor yourself unless you are certified in air conditioning, gas in system can kill you if you breeth it in.

just try to turn the pully if its stiff there is a fault
