SOURCE: Needing to remove ac compressor to install ac bypass pulley

There are a couple of ways to approach this. I just did one of these for a friend. The A/C pump seized while running. The serpentine belt broke. Crazy things can happen to other components when this occurs. In this case the broken ends of the belt, I think, whipped back around on itself on the crankshaft pulley and one of the other pulleys in the belt circuit and devastation occurred. 1) It snapped the power steering pump bracket in two. 2) It took out the alternator. 3) And not to be left out, GOODBYE cool blowin air conditioning. Time to decide what to do. He had to order the power steering bracket from a dealer (junk yards were cleaned out). He decided to replace the power steering pump with a remanufactured unit and new hoses (parts houses are much cheaper than dealer parts folks). You'll need a pulley remover that you can usually borrow (with a deposit) from some parts houses. He HAD to buy the alternato ya gotta have juice. I have been using the name, "parts houses" . (Can we use specific company names in this forum MR./MS. Editors ? I Feel I need to for the sake of all of us that come here for correct information.) THE ANSWER : DO you want to drop the bucks into fixing your A/C ? NO ? It can be involved and costly depending on how good of a do it yourselfer you are. New pumps are spendy. Then, if you use the older refridgerant you'll need a conversion kit and blah blah blah. YOU have opted for a bypass pulley. COOL ! Errrr...not actually. It's coming out. The bolts that hold the A/C pump to its bracket come out from BEHIND the bottom of the unit. They are long and won't clear the intake manifold,at least not easily. Take the bracket bolts out from the front. Take the hose from the pump to the dryer apart (at the dryer). Do you want to preserve the system for future repair? If so, cover that connection on the dryer to protect it from the world. With a sharp blade, cut the other hose coming off the pump right behind the grill. Or, try to take the fitting apart at the evaporator. Cutting it is easier. Plug the cut off end if ya want. Future repair thing. Rotate the pump forward so you can either take the bolts out,or remove the pump and bracket as a unit, with the lengths of hose attatched to the pump. This gets all that hose you no longer need out of the engine compartment. NOW THE BYPASS PULLEY. He found a pulley from NAPA. IT DOES NOT WORK ! YOU DO NOT NEED IT ! Nothing against NAPA. I have bought good parts from them before. Maybe their supplier does not know. The pulley is supposed to drop into the A/C bracket in the concave recess that the pump once occupied. IT WASN'T EVEN CLOSE. Chevy released THREE versions: Poor Boy-no power steering,no A/C. MIDMan-power steering,no A/C. Rich Guy-power steering,with A/C. SO....... If you have power steering, the A/C pump removal just put you into Midman status. Stop at your local chevy dealer, ask them to print you a belt routing diagram from the computer parts book. It shows all three versions. Go to your local,,,,,,,"PARTS HOUSE", tell them info...year,make,engine size, REMEMBER.. IT NO LONGER HAS AIR CONDITIONING. YOU'LL GET A SHORTER BELT !! IF, they sold you the bypass pulley.....GET YOUR MONEY BACK !!! Use the diagram you got. The belt is routed a little different since you lost the A/C pump and the idler pulley with it's bracket(that you can keep for future repair or trade in for to be made into beer cans) Also remember that without a belt on, the tensioner pulley is swung over to the end of it,s range of motion. When you get the belt routed correctly you have to put a wrench on the bolt on the pulley and turn hard to compress the spring. (COUNTERCLOCKWISE) The bolt is left hand thread so it won't come loose while ya reef on it to get the belt swung onto the ALTERNATOR LAST.<<<<<<GOOD LUCK !!! ADDED NOTE: Would that bypass pulley work on say...an "88" or "89" or "90" ? > I DO NOT KNOW. DID CHEVY change the size of the pump bracket after 87 ? We will be letting the good folks at NAPA know what we ran into and how we fixed it. We also will ask for a refund on the wrong part for the job. IT DOES NOT FIT AN 87! WE DO KNOW THIS..... IF the belt had just broke in half and safely dropped away, then all those parts wouldn't have been needed and the cost of the fix is FOR A SHORTER BELT and a little sweat to remove the A/C pump and bracket. The A/C NEVER WORKED ANYWAY

Buy a whole new clutch for about $200. You need a special puller to remove the old one if you intend to refurbish it. It's not worth the effort. Just remove the clips and knock the old one off with a hammer. Chuck it away and replace with a brand new clutch assembly.

2005 Murano started out making a high pitched whining sound when the AC was on. Now the sound is constant even when the AC is off. The faster i go the faster the progression of the whining. help .

The air conditioner compressor is driven by the engine. The compressor itself has a pully on it that is mounted to an electric clutch, When the Air condition is no on, the pulley still rotates on the shaft but the clutch is not engaged so the compressor does not turn. If the whole assembly is starting to wear then the bearings in the pulley will whine. Due to the the heat that builds up from this, the dealer or service tech will replace the whole compressor and the clutch, You are looking at a cost of near 2 thousand dollars.

There are several pulleys necessary for the A/C. The A/C clutch pulley on the AC compressor is one. If this is the one breaking, your compressor is not far behind. The resistance of the compressor is minimized by proper oil TYPE and proper quantity of oil and freon to keep the compressor bearings free. Now if you are talking about the tensioner pulley, both the AC clutch pulley and the tensioner can be too tight if the belt routing is wrong. On some engines the belt can be routed 2 ways. To save money, the belt could be looped to eliminate the AC, and another way to have a working AC. Could be the belt is installed wrong. There are different types of AC oils.

If you have a separate belt driving the ac compressor then leave the belt of. IF it has to go around the ac pulley then disconnect the power lead at the pulley clutch and again no problems as the ac pullet becomes an idler.

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.

DONE

Noisy AC compressor Jaguar X type 2.0D

Isn't there an old trick where soap on the belt can quiet things down ?

That might help you decide whether the belt needs replacement.
