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

SOURCE: believe ac compressor pully is locked up not sure where located a

front of engine down low on passenger side (access from under the car), there is no AC delete option so the compressor should be there and not bypassed, what is the question about the AC? it doesn't work?

SOURCE: on a 2001 saab 93 turbo can can you bypass the ac

You can bypass both the AC compressor and the middle serpentine idler pulley with a 6PK1790. The middle pulley is bypassed by running the belt straight line from the upper rear serpentine idler straight to the power steering pulley, then over the water pump (the smooth pulley powered by the back side of the belt) and down to the engine drive pulley (harmonic balancer), bypassing the AC compressor) This works fine. On 9.5 models, the same basic idea, but a slightly different sized belt.

There is a pulley that fits where the compressor is mounted. This means that the compressor would have to be removed and the a/c hoses would have to be sealed.

2001 chevy venture what size is belt that bypasses a.c. compressor the exact measurements


There is no belt to bypass the AC cataloged, when the AC is not ordered on the car (AC delete) or the compressor is removed for some reason then you must use what is called an AC delete pulley, it bolts in place of the AC compressor and you use the same belt. The pulley is cheap and either the dealer or most good auto parts stores like NAPA (or others) can order it for you, in the aftermarket the pulley's are made by a company called DORMAN

Tried to replace my ac pully with a bypass pully removed all the bolts and I still can't get it budge to remove it.. I say for an hour trying but no luck help?


If you are installing a bypass pulley it will eliminate the A/C compressor thus eliminating your A/C. With that being said, you need to evacuate the system. (If there is anything in it), Remove the whole A/C compressor from the car and then install the bypass pulley where the compressor would mount to the engine. If you are trying to remove the pulley on the A/C compressor to replace it then you will need a special tool (A/C Clutch Pulley Puller) that is usually available at most auto parts store on the "Loan a Tool" programs.

The ac compressor is seized .I need to replace belt but I need to bypass the ac pulley.Do i need to buy a bypass pulley?


If the pulley on the compressor will not turn freely, then yes if a bypass pulley exists you would need to use it in place of the compressor.
If the compressor pulley turns but the compressor is locked up, just unplug the compressor clutch.

Belt broke on 2000 chrylser convertible ac compressor froze i need diagram to show how to bypass it


I don't think you can bypass the compressor.
Chrysler would have to build a model without ac and as far as I know they all have ac.
When they do have an engine without ac they usually have an idler pulley to take the place of the compressor.
Re-routing the belt runs the risk of turning the alternator or water pump in the wrong direction.

How to install a/c bypass pulley on 1988 buick park avenue


Most ac bypass pulleys simply bolt on where the ac compressor was. when you remove the compressor save the bolts. AC bypass pulleys are car specific. Each one is made to fit a specific engine. there is no such thing as a universal so make sure that you have the correct one.
