99 chrysler lhs a/c comressor pulley frozen

The motor is the 3.5 HO. The ac compressor pulley is locked tight, and I'd like to just remove the belt and go without AC, but there's another pulley below it and I can't see what it connected to. Is it the water pump or anything as important, or can I safely take the belt off.

    The lower pulley is the tension pulley. You can remove the AC belt and it will not affect the engine operation. This belt turns only the AC compressor and no other function engine parts. I was able to unplug my ac compressor to keep it from engaging the clutch allowing it to turn freely. If your ac pulley won't turn at all, then you have no other option but to remove or cut off the belt. It would be much easier just to cut it off and buy a new one when you are ready to replace it. I purchased one recently for $4.99. Good luck!

I had the same problem coming back from Hilton Head Island over July 4th weekend. I had been experiencing a grinding noise for sometime coming from the a/c compressor pulley. Aside from the noise, the a/c had been blowing strong, and cold with out any problems. Unfortunately I neglected it for too long, and it locked up after a terrible squeal, followed by a little smoke (belt burning). I cut off the belt, and was on my way. Granted it was a bit hot, but I was sure glad I was able to get home! I have found replacement a/c compressors w/clutch online from $200-$350 depending on condition (rebuilt vs new). I strongly recommend attending to the problem at the first sign of any noise.

Belt replacement mazda3 2006

i do hope this helps its for the serpentine belt
First, jack up the caricon1.png, use jack stands, yadda yadda etc.

Remove the lower splash shield.

Youll see a skid plate looking thing on the ac compressor, remove that with a 12mm socket.

Now you have to remove the AC compressor. There are four stud/bolt things holding it on. Also 12mm.

Once the bolts are out the AC compressor is basically held up by the belt and the AC lines. Work the AC belt off of the pulley and then secure the ACcompressor out of the way. Dont let it hang by the AC lines.

Go back up to the top of the engine and remove the engine cover, it just pulls right off.

Youll see the serpentine belt and the tensioner pulley (basically the pulley at the front of the motor and right on top).

Note the routing of the belt for reinstallation.

Put a socket on the tensioner pulley (either 12 or 14mm) and push towards the firewall.

Youll see the belt loosen.

Now slip the belt off of the tensioner pulley.

You can release the tension on the pulley slowly now.

Work the serp belt off of the rest of the pullies.

Installation is basically the reverse of removal, but it can be tricky to route the belt on since its new and rigid. It helps to have a friend push on the tensioner while you route the belt. I managed to do it by myself, but I have long arms. It also took me several tries and much swearing!

Now putting the AC belt back on can be tricky due to the fact that it is a stretch belt, and will be very tight.

I slipped the belt on the crank pulley and then pulled the AC compressor up as high as I could. Then I could slip the belt on. Little note here, because the belt was so tight the compressor wouldnt slip back into position. I used my floor jack on the bottom of the compressor and very slowly pushed on it with the jack.

Then line up the AC compressor, resecure the bolts/nuts etc.

Reinstall splash shield.

Bypassing the a/c pump with a shorter belt

If it isn't a Serpentine belt then you can get the main motor belt for a motor without AC and put that on. Now, you may have to remove the AC compressor completely if the routing is blocked by that AC pulley. Normally this is not needed though unless your AC clutch has frozen. You can disable the AC by just turning it off or disconnecting the power wire from the compressor in the engine compartment.

How to bypass the ac with a shoter belt

There is a easy way to re-route the belt after the A/C is removed on any 4.6L Due to the idler and tensioner. When the a/c is not running the pulley spins freely anyway. On 99 and older panthers you can get a shorter belt to bypass the power steering for a little extra power, but need install A/C COMPRESSOR BYPASS PULLEY, or you could buy a a/c compressor delete kit comes with a bracket and idler pulley, that would make things easier, you can use a stock belt with that kit.

Check this for 99' and older belt routing...


Also, check this diagram (click over pic for zoom)...


The tensioner would still work, just not very well. So you would need to by a tight belt to compensate. As far as measuring the new belt size, you will need to use a tape measure, or some string and then measure the length. The best option is an a/c delete 'kit'

Green line represents a revised belt routing in order to *bypass* the A/C compressor. With this method, the tensioner WILL work but VERY limited - you must purchase a tight belt.

Note this is only applicable for the '93-'99 belt routing

Hope helps (remember to rate and comment this answer).

I need to replace the a/c compressor belt on a chrysler 2000 LHS, how do I loosen the tension pulley to remove the first belt?

Hi, I believe there is a tensioner that is situated below the alternator and have to loosen up gradualy and then you belt will come off the crank/water pump/alternator and then remove the a/c compressor belt, and also if you don't need to run your a/c or you dont want to chang the compressor you don't need that belt, your vehicule will run fine, that belt run only you a/c compressor Mike

When ac or defrost on clutch engages and motor has a serious load that effects idle... and ac stop blowing cold air

sounds like the compressor is beginning to lock up (with engine OFF)remove the belt off the pulley on the compressor,then switch on the ignition and turn on the A/C switch so the pulley is engaged then turn the pulley by hand and see how tight it turns,there should be some drag,but not so much as not to be able to turn it w/o force

How to change the belt on 1996 pontiac boneville

on the 3.8 liter v6, the pulley on the a/c compressor can be replaced if it is locked up (frozen) on the compressor. the question is what is actually locked up? if the a/c compressor is locked up but the a/c compressor pulley turns, then you need to disconnect the wire harness connecter that is on the a/c compressor pulley/clutch so you can run the defrost on the climate control. many GM cars will run the a/c when you switch the climate control to defrost especially in the winter so the a/c system stays lubed and does not lock up the a/c compressor from lack of use. you can then relace the belt without replacing the compressor pulley/clutch assembly. if the compressor pulley/clutch assembly is locked up, it will need to be replaced. i do not believe there is a way to route the belt bypassing the a/c compressor. you dont want the water pump turning in the wrong direction if you reroute the belt wrong or the engine will overheat. i hope this helps!

Fan Blower working, just not getting any cold air

The tensioner pulley is not turning??? Have you been burning up belts left and right?? Is the belt tight against the tensioner pulley?? You need to check to make sure that pulley is operating correctly. Are you getting good charge out of your altenator?? Is it hard to turn do to lack of power steering?? Have you thrown the belt multiple times?? If that pulley is not spinning there is only to causes for this. Either the pulley is froze, or there is no tension against the pulley. If the pulley is frozen you should be burning up belts often. The tensioner pulley spring is broke and not holding the proper tension. The belt might still be rotating, but the belt will not be rotating the other accessories attached like it should be. My chrysler van has a dual belt set up and yes if the tension pulley is not moving then you will be lacking the rotation need to make the ac compressor operate properly.
